KE153 Signal Processor is an optional supplement to AMETEK’s SPECTRATM BC10 and GT10 Flame Sensors. Used in conjunction with these flame sensors, the KE153 takes the 4-20 mA sensor output and provides signal gain, four (4) relay outputs, frequency discrimination, continuous system self-check, Modbus communication, a front panel display, and redundant power input for the sensor.
The KE153's frequency discrimination feature allows it to filter out background radiation from hot, glowing boiler walls and also the radiation interference from neighboring burners. This discrimination capability ensures that when a flame is extinguished, the relay trips immediately because there are no background radiation effects, i.e. no false positives and no false trips.
All of the functionality of the KE153 Signal Processor is easily programmable on the unit or using AMETEK’s optional AmFlameTM PC interface software. In addition to remote programming, AmFlameTMTM will also keep track of all program settings, changes, and can record sensor output data for analysis.
FEATURES AND BENEFITS
- Multiple Outputs—interface to BMS or controller with relay contacts, analog signal,and via RS485 digital Modbus
- Discrimination—provides frequency discrimination for reliable burner management
- Redundant Power Supply—dual 24 VDC power inputs to Signal
- Processor provide backup power to flame sensor
- Local or Remote Programming—provides flexible and convenient monitoring & control
- Front Panel Display—bar graph indicates sensor output signal and LEDs provide relay status
- FM Approval-meets FM requirements for Flame Standard (FM7610) and Class I Div. 2 electrical safety (FM3611)
