HOT WATER AND STEAM BOILERS
FLAME MONITORING DEVICE F152
Flame monitoring device
Digital flame frequency evaluation in the range of 10 – 200 Hz
Approved for continuous operation
Plug-in module for top hat rail mounting
Two -channel system with electronic self-monitoring
LED based status display
Measurement output for intensity 0-20mA
No modifications needed for country-specific mains frequencies
SIL 3 DIN as per EN 61505-2
Purpose:
The F152 is housed in a plug-in module for top hat rail mounting and together with the scanner FFS07 / FFS08 forms a safety device for optical monitoring of burner flames without complicated selection tasks. The flame monitoring device F152 is designed as a two-channel system with electronic self-monitoring. Adaptation to country-specific mains frequencies is not necessary, as they are suppressed by sliding fade-out. It has digital flame frequency evaluation and LED status displays. In addition, the device is supplied with a measuring output for intensity in the range 0-20 mA.
The FFS07 and FFS08 scanners are equipped with sensors for IR or UV range according to customer requirements. The system is suitable for monitoring tasks without high selection requirements for single and multi-fuel burners in heating plants and process furnaces that are operated with oil, gas, biomass, dust or process gases.
The flame monitoring device F152 and the probes FFS07 and FFS08 are certified according to IEC61508 part 2 according to SIL 3 and comply with the standards DIN EN 298 for gas operation and DIN EN 746-2 for process plants. The requirements of the Pressure Equipment Directive (2014/68/EU) and Gas Appliances Directive (2009/142/EC) are also met. An Ex-I certificate for the FFS07 scanner is also available.
