trodeks’s TX-M12-RTD Series RTD transmitters offerimproved performance over conventional in-headtransmitters yet are a fraction of their size and weight.Integral M12 connectors maintain IP67 protection andconnection integrity while allowing for a quick andsimple change of sensor. Two models are availablewith either 4 to 20 mA or 0 to 10 Vdc output. Defaultscaling for the full output is 0 to 100°C (32 to 212°F),other ranges can be scaled at time of purchase for anadditional charge; or the optional USB programmingmodule (USB-CONFIG-UNIT) will allow the end user toperform scaling.

The TX-M12-RTD transmitter is ideal for use withtrodeks’s 4-wire PR-21, PR-22 and PRS-M12 Series RTD probes, or anyRTD probes with an M12 “A” coded pin style connectorwhich connects directly to theTX-M12-RTD sensorinput. 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 styleconnector. 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.
