Pyrotech electronics offers microcontroller based digital temperature scanners [scn-200, 300 and 400]. These scanners accept rtd pt-100, thermo-couple, dc ma or dc volt input with up to 32 channels and are highly reliable. Common dead-band facility is available with relay output for alarm/trip. Alarm and trip setpoints are programmable.
Cold-junction compensation for thermocouple input and lead-resistance compensation for pt-100 sensor input are also provided.
The salient features of the scanner are auto-scan, hold mode and skip facility with zero and span calibration through software.
