¡ß Head mounting type temperature transmitter ¡ß
¡Ü Model : R912 (with T990)
¡ß Service intended :
These transmitters are recommended be used in the situation where the application of RTD signals to carry to a long distance or to guard against the heavy electrical field noise. The transmitters convert RTD inputs to an analog signal for a direct interface with indicators, recorders, controllers, PLC, DCS systems, and these can be used for a wide range of applications in process control, automatic machinery and hydraulic or pneumatic system design.
¡Ü Advantages :
- Two wire 4 - 20 mA current output signal
- RTD input
