RTD Temperature Transmitters

With the assistance of our partner, Metromatics is able to offer a range of RTD Temperature Transmitters.  They are available in single or dual channel versions, two, three or four wired models, loop powered, high voltage isolated, voltage or 4-20ma outputs and some models are USB configured.

They accept a range of inputs from standard 100 ohm Pt RTD up to 900 ohm, ohm Ni, ohm Cu, linear resistance and other universal inputs.


RTD Temperature Transmitters are a device which is connected to the temperature sensor.  It converts Platinum, Copper, Nickel RTD or Resistance Sensor Input signals to 4-20mA or 0-10V DC.  It then transmits this information to interfacing controllers or other instrumentation.  Where it is logged and maintained.

Acromag have a range of EMC Compliant RTD Temperature Transmitters.  Click on the images to be taken to the Acromag page for more product specific information.

Metromatics sell and support this product range in Australia.  Finally, for more information, contact us.
