SEM1801XTC / 1802XTC Temperature Transmitter
Brand: Status InstrumentsThe SEM1801XTC/18022XTC Din rail temperature transmitter accepts thermocouple temperature sensors and converts the sensor output over a configured range to a standard industrial (4-20 mA) transmission signal.
Two versions are available; single or dual channel ATEX / IECEx approved for hazardous areas.
PC configuration allows the user to select TC type, Range, Filter, units, linearisation and Burnout direction, without requiring calibration equipment.
Additionally, the user may read live process data when connected to the PC (in the safe area), this allows for sensor offset, and output alignment calibration, where the user can enter values to match the actual process and therefore reducing system errors.
