A 4-20mA PT1000 RTD PLC Sensor Transmitter

by Editor on September 21, 2007

The Robert Owen Inc. ROI-XMA 4-20mA sensor transmitter now enables PLC PT1000 RTD temperature measurement
Albertson NY, USA – Robert Owen Inc. temperature transmitters offer temperature ranges as wide as -200 to 500 Deg C or as small as 0 to 32 Deg C, depending on the make and model.

Now, in addition to the ROI-XMA-RTD working with standard PT100 platinum 100 ohm RTDs, which convert the RTD resistance to 4-20mA current loop format, making the measurement suitable for long distance transmission, the ROI-XMA-RTD works with PT1000 RTDs.

With ROI-XMA; you can use PT100 RTDs and PT1000 RTDs with standard industrial PLC’s and industrial I/O. The ROI-XMA series of loop powered RTD transmitters, convert a RTDs temperature related resistance change into a standard 4-20mA instrumentation signal.


Input 1000 Ohm RTD temperature sensor data, into your PLC; using standard 4-20mA, 0-20mA, 0-5Vdc, or 0-10Vdc input A-D channels. No need to replace working sensors, you can signal condition your sensors to make them compatible with most modern industrial control systems.

The ROI-XMA Features:

* Pluggable sensor Euro connectors
* Snap on mounting base for DIN rail or surface mounting
* Loop powered sensor transmitter, signal conditioner format

Useful for interfacing existing HVAC and refrigeration system RTD temperature sensors, with modern industrial control systems. Accessories such as signal isolators and trend recorders are available.
