The SEM104P is a temperature transmitter designed to accept a standard platinum resistance sensor (Pt1002 or 3 wire) to BS EN60751 , BS1904 or DIN43760 and convert the temperature to industrial (4 to 20) mA. It is housed in a purpose designed DIN standard connecting block enclosure. The transmitters are available in 6 standard factory calibrated ranges, but the transmitter can be user re-ranged to operate over most temperature ranges encountered in both industrial and building management applications. Non standard ranges can be supplied to special order. The enclosure provides trim potentiometer access, allowing fine re-calibration adjustments to be made at both ends of the scale.
