KE153 Flame Sensor Signal Processor
The
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, AmFlameTM provides
remote PC monitoring of the flame sensor output and the condition of
the four relays. AmFlameTM will
also keep track of all program settings, changes, and can record sensor
output data for analysis.
