Programmable multi input temperature transmitter

Model: T900


Service intended

T900 series temperature transmitters are designed to fit into a standard molded terminal heads used on RTD and thermocouple assemblies to provide a 4~20 mA transmission signals. It is a cost effective solution for all temperature measuring process. It is accurate, durable and reliable.


Numerous configurations for measurement in many deferent mediums are offered. Generally the transmitter produces a linear 4~20 mA output carried on a two-wire system. The transmitter is supplied factory
calibrated, but also has zero and span potentiometers for a field adjustment.
