Head mounting type temperature transmitter (RTD only)_R912 (with T990)
Type: R912
 
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.
 
Advantages
 
■ Two wire 4 - 20 mA current output signal
■ RTD input
■ Measuring range from -50 ~ 400 ℃
■ Fixed range
■ Excellent accuracy and long term stability
■ Low - cost
■ Miniature design
