You should consider APAQ-R130-TTC T thermocouple transmitters. Because they let you use T thermocouples with spare PLC 4-20mA inputs for temperature measurement.
T Thermocouple temperature transmitters
The APAQ-R130-TTC series is a versatile family of loop powered 4-20mA thermocouple temperature transmitters, because the signal range is scalable to alternate T thermocouple temperature spans within sensor range, and the supply voltage range is from 7.5 to 36Vdc. As well as the output circuit is reverse connection protected and filtered.
When you have spare PLC 4-20mA inputs, and need to add temperature measurement, use the APAQ-R130-TTC thermocouple transmitter. Because the APAQ-R130-TTC thermocouple transmitters allow the simple measurement of industry standard thermocouples. They use the standard 4-20mA signal. So, you can easily connect your existing T thermocouples to modern control systems. They are a simpler way to add temperature measurement to a PLC than other types. T thermocouples have higher precision than other thermocouples. Because T thermocouples are accurate at low temperatures, they are useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryer, and other limited temperature range applications.
When you need a 0-50C T thermocouple 4-20mA 2 wire loop powered temperature transmitter, use the APAQ-R130-TTC. In other words, T thermocouple 4-20mA transmitters are a simple way to add temperature measurement to a PLC.
