R912 TEMPERATURE TRANSMITTER ( WITH MTM )

Description

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
