The ROI-10KXMA series are simple to use loop powered 4-20mA 10K NTC thermistor temperature transmitters. Available in a number of ranges (e.g. 0 to 50 Dec C range input and 4-20mA output). 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-10KXMA thermistor transmitter. The ROI-10KXMA thermistor transmitter allows 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.
