The M12TX RTD transmitter is easily ranged and programmable by a computer. The configuration kit required for programming is M12TX-CONFIG. This unique transmitter is ideal for areas with space limitations where traditional head connections are too large to fit. The M12 thread design offers a secure industrial connection. The integrated connection allows the transmitter to be mounted directly on to the sensor.
