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.


Elevate your monitoring systems with our range of RTD Temperature Transmitters.  Firstly, engineered to seamlessly convert input signals from Platinum, Copper, or Nickel RTD sensors into universally recognised 4-20mA or 0-10V DC outputs. These transmitters are not just devices.  They are the nerve centre of your temperature sensing equipment.  Because they adeptly transmit critical data to your controllers and instrumentation, where it can be correctly logged and managed.

Delve into Acromag‘s selection of EMC Compliant RTD Input Temperature Transmitters.  Each meticulously crafted to ensure impeccable performance in even the most demanding environments.
