THERMISTOR 4-20mA 2 wire loop powered transmitter
The ROI-XMA series is a versatile family of loop powered 4-20mA bridge transmitters. Versions can be provided for resistances, between 1K ohm and 10K ohm impedance. Signal range can be custom scaled to alternate spans within sensor range. Transmitter supply voltage may be from 7.5 to 36Vdc. Output circuit is reverse connection protected and filtered.
The ROI-XMA series is a versatile family of loop
powered 4-20mA thermistor temperature transmitters. Versions can be provided for
thermistor Base Resistance (Ro), between 1K and 100Kohm impedance (@ 25 Deg C). Signal range
can be custom scaled to alternate thermistor temperature spans within
sensor range. Transmitter supply voltage may be from 7.5 to 36Vdc.
Output circuit is reverse connection protected and filtered.

Use spare PLC 4-20mA inputs for temperature measurement, with the ROI-XMA thermistor
transmitter. ROI-XMA thermistor transmitters allow the simple
measurement of industry standard thermistors. Existing 10K ohm NTC
thermistors can be connected to modern control systems. The thermistor
is a simple way to add temperature measurement to a PLC. The
thermistor is ideally suited for limited temperature ranges can be
used to achieve higher precision than other
temperature sensors. Useful in HVAC systems, refrigeration systems,
chillers, environmental monitoring, computer room monitoring, dryer, and
other limited temperature range applications.
