Mini RTD Temperature Transmitter With M12 Connectors

Omega’s TX-M12-RTD Series RTD transmitters offer improved performance over conventional in-head transmitters yet are a fraction of their size and weight. Integral M12 connectors maintain IP67 protection and connection integrity while allowing for a quick and simple change of sensor. Two models are available with either 4 to 20 mA or 0 to 10 Vdc output. Default scaling for the full output is 0 to 100°C (32 to 212°F), other ranges can be scaled at time of purchase for an additional charge; or the optional USB programming module (USB-CONFIG-UNIT) will allow the end user to perform scaling.

The TX-M12-RTD transmitter is ideal for use with Omega’s 4-wire PR-21, PR-22 and PRS-M12 Series RTD probes, or any RTD probes with an M12 “A” coded pin style connector which connects directly to theTX-M12-RTD sensor input. Other 2-wire, 3-wire or 4-wire RTD probes, as well as slide wire resistance devices, can be easily connected to the TX-M12-RTD transmitter by using a field mountable M12-R-M-FM or M12-S-M-FM plug style connector. Please see the wiring diagrams below for 2-wire, 3-wire and 4-wire RTDs, as well as other slide wire resistance devices.

Don't forget to order an M12 extension cable to connect your transmitter to your process instrumentation.
