COMECO’s current loop transmitter TRN converts the signal from a temperature sensor into standard current or voltage signal that can be safely sent over long distances to remote indicators, data loggers, or controllers. In addition to the most common thermoresistance and thermocouple sensors, TRN may convert linear analog input signals (current or voltage). The transmitter is based on high-tech integral circuits and has fixed input range. Two-wire- and three-wire-output variants are offered. Both are available in case for mounting inside sensor protection head, in watertight box with high protection class, in case for mounting on a DIN rail, and in case prepared for mounting in Ex housings. TRN can withstand considerable electromagnetic disturbances and is a perfect low-cost solution for general-purpose applications.
