When selecting the right flame amplifier for industrial monitoring systems, understanding the key distinctions between different models is crucial for optimal performance and safety. The 3001 and 3016 amplifier variants each offer unique capabilities designed for specific industrial applications. Both serve essential functions in flame detection systems but differ significantly in their technical specifications, operational parameters, and ideal use cases. This comprehensive guide explores these distinctions to help industry professionals make informed decisions when implementing or upgrading flame monitoring systems.
What is the difference between flame amplifier types 3001 and 3016?
The fundamental distinctions between these two popular flame amplifier models lie in their technical specifications, operational parameters, and design philosophy. The 3001 model represents a versatile solution with longer safety switch-off times (1-6 seconds), making it suitable for applications where brief flame interruptions are expected. In contrast, the 3016 variant features significantly faster response times (200-650 milliseconds) for applications requiring immediate reaction to flame loss.
While both amplifiers function as 19″-slide-in modules within the flame monitoring and evaluation system 3000, they differ in several key aspects. The 3001 offers greater temperature tolerance, operating effectively between -20°C to +70°C, whereas the 3016 has a narrower range of 0°C to +60°C. This temperature distinction makes the 3001 more suitable for extreme environment applications.
Another significant difference is in their certification profiles. The 3001 (including variants 3001S/3001D) achieves SIL 3 certification when combined with specific flame scanners (2.0, 2.0GT, 2.0L or 2.0LA), while the 3016 maintains SIL 2 certification. This higher safety integrity level makes the 3001 preferable for applications with stringent safety requirements.

Both amplifiers maintain core similarities, including 24V DC power supply requirements, approximately 300mA current consumption, and fail-safe design with self-checking functionality. They also share the same flame intensity output capabilities (0/4 to 20mA) and cable length specifications.
How do flame amplifiers 3001 and 3016 work?
These sophisticated flame amplifier modules operate through advanced signal processing techniques that interpret data from connected flame scanners in the 3000 series. The fundamental operating principle for both models involves continuous monitoring of flame presence through detection of specific flame characteristics like ultraviolet radiation, infrared signatures, or flicker frequency patterns.
The 3001 amplifier employs a more deliberate signal processing approach, analyzing flame signals over longer intervals to ensure stability and reliability. Its internal architecture includes multiple sensitivity ranges that can be selected remotely, allowing for calibration to specific flame conditions. The self-checking mechanism activates once per second, verifying all critical safety functions to maintain operational integrity.
In contrast, the 3016 utilizes more aggressive signal processing algorithms optimized for speed. Its internal components are engineered for rapid state changes, allowing the system to react almost instantaneously to flame loss. The 3016 incorporates an additional failure alarm relay output that provides enhanced diagnostic capabilities compared to the 3001 model.
Both amplifiers communicate with burner control systems through standardized interfaces. They process the raw flame signals from scanners and convert them into actionable outputs: analog signals (0/4-20mA) indicating flame intensity and relay contacts that provide binary flame presence information. The relay outputs are designed with safety-critical applications in mind, featuring internal fusing (1A) to prevent hazardous conditions during fault scenarios.
The self-checking mechanism represents a critical safety feature in both models. This system continuously monitors internal components and circuitry, ensuring that any failure within the amplifier itself will be detected and trigger appropriate safety responses. This functionality is essential for maintaining SIL (Safety Integrity Level) certifications and ensuring reliable operation in hazardous environments.
Which applications are best suited for flame amplifier type 3001?
The 3001 flame amplifier excels in applications where operational stability and environmental resilience are paramount concerns. Power generation facilities, particularly those with multiple fuel capabilities, benefit from this model’s adaptability and longer safety switch-off times. The extended timing parameters (1-6 seconds) make it ideal for combustion processes where momentary flame instabilities are expected but don’t necessarily indicate dangerous conditions.
Waste incineration plants represent another optimal application for the 3001 model. These facilities often experience variable fuel quality and combustion characteristics, requiring flame monitoring systems that can accommodate brief interruptions without triggering unnecessary shutdowns. The 3001’s ability to maintain flame monitoring integrity across a wide temperature range (-20°C to +70°C) makes it particularly valuable in these challenging environments.
Specific industrial settings where the 3001 demonstrates superior performance include:
- Rotary kiln operations – Where rotating equipment may cause periodic flame signal variations

- Facilities experiencing frequent weather-related temperature fluctuations
The 3001 also offers excellent compatibility with a wide range of burner types, including those using multiple fuel sources or operating with low NOx configurations. Its selectable sensitivity ranges allow fine-tuning to specific flame characteristics, making it adaptable to various combustion technologies and fuel types including natural gas, oil, coal, and waste streams.
Which applications are best suited for flame amplifier type 3016?
The 3016 flame amplifier is engineered specifically for applications where rapid response to flame conditions is critical for safety and operational integrity. Gas turbine installations represent the primary application domain for this model, as these systems require immediate reaction to flame loss to prevent potentially hazardous conditions. The 3016’s quick safety switch-off time (200-650 milliseconds) provides crucial protection in these high-energy combustion environments.
H2S plants and Claus units in the petrochemical industry also benefit significantly from the 3016’s rapid response characteristics. These processes involve highly reactive and potentially dangerous substances where combustion must be tightly controlled. The additional failure alarm relay output in the 3016 provides enhanced diagnostic capabilities that are particularly valuable in these critical applications.
Industrial environments where the 3016 delivers superior performance include:
- Duct burner systems – Where rapid flame detection and response are essential
- High-pressure combustion processes – Requiring immediate system response to abnormal conditions
- Crackers in petrochemical facilities – Operating with precise timing requirements

The 3016 model performs optimally in controlled temperature environments, with its operating range of 0°C to +60°C being suitable for most indoor industrial settings. Its specialized design makes it particularly effective in applications where flame signals are expected to be consistent and stable, allowing the system to react decisively to genuine flame loss events without false alarms.
For industrial facilities prioritizing rapid safety response over accommodation of flame variability, the 3016 represents the optimal choice in flame amplification technology.
Are flame amplifier types 3001 and 3016 interchangeable?
While both amplifiers utilize the same 19″-slide-in module format and share basic connection interfaces, they are not directly interchangeable without careful system evaluation and potential adjustments. The significant differences in response timing characteristics represent the primary compatibility challenge. Replacing a 3016 (200-650ms response) with a 3001 (1-6s response) could introduce dangerous delays in safety system activation, while the reverse substitution might cause nuisance trips due to overly sensitive response times.
Wiring considerations present another important compatibility factor. Though both models use similar connection schemes, the 3016’s additional failure alarm relay output requires appropriate terminal connections that may not be present in systems originally designed for the 3001. Proper terminal mapping and potentially additional wiring would be necessary to fully utilize this diagnostic feature when upgrading from a 3001 to a 3016.
Mounting arrangements are generally compatible between models, but system integrators should verify physical clearances and cooling requirements, particularly when installing the 3001 in environments approaching its temperature limits. Both amplifiers require the same power supply specifications (24V DC), making power system compatibility less problematic.
When considering substitution between these models, several system adjustments may be required:
- Control system programming – Particularly timing parameters and alarm response protocols
- Flame scanner sensitivity settings – To accommodate different amplifier response characteristics
- Safety certification validation – Especially when moving from SIL 3 to SIL 2 capabilities
- Operating procedure updates – To reflect different troubleshooting approaches
- Functional safety assessments – To verify system integrity after component changes
We recommend consulting with flame safety specialists before attempting to substitute between these amplifier types to ensure all safety and operational considerations are properly addressed.
How do you troubleshoot common issues with flame amplifiers 3001 and 3016?
Effective troubleshooting begins with understanding the specific indicators provided by each amplifier model. For both the 3001 and 3016, the first diagnostic step involves checking the flame intensity output signal (0/4-20mA). This analog value provides crucial information about signal quality and can identify issues like weak flame detection or improper scanner positioning. Values consistently below 4mA often indicate flame detection problems requiring immediate attention.
For signal loss issues with the 3001 amplifier:
- Verify scanner alignment with flame envelope
- Check for contamination on scanner viewing window
- Confirm proper scanner-to-amplifier connections
- Test multiple sensitivity settings via remote selection inputs
- Verify power supply voltage stability (24V DC ±10%)
The 3016 amplifier requires slightly different troubleshooting approaches for signal problems:
- Examine failure alarm relay status for diagnostic information
- Verify operating temperature remains within 0°C to +60°C range
- Check scanner-to-flame distance (may require closer proximity than 3001)
- Test with shorter safety switch-off time settings to identify intermittent issues
- Inspect all connection terminals for secure contact
For false flame detection scenarios, both models require systematic investigation:
- Identify and eliminate potential sources of background radiation
- Check for optical crosstalk between adjacent flame scanners
- Verify proper grounding of all system components
- Inspect for moisture ingress in scanner connections
- Consider replacing the scanner if problems persist
Preventative maintenance practices differ slightly between models. The 3001 benefits from quarterly inspection of operating temperature conditions and annual verification of safety timing functions. The 3016 requires more frequent verification of the failure alarm functionality (recommended monthly) and careful monitoring of response time consistency.
For both amplifier types, maintaining comprehensive documentation of performance parameters, test results, and any adjustments is essential for regulatory compliance and effective long-term system management. When troubleshooting reveals persistent issues that cannot be resolved through standard procedures, consulting with specialized technical support is recommended to ensure continued safe operation.
