Head Mounting Type Temperature Transmitter (RTD Only) R912 (With T990)
Brand: Wise Control IncThese 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

- RTD input.
- Measuring range from -50 ~ 400 ℃.
- Fixed range.
- Excellent accuracy and long term stability.
- Low - cost.
- Miniature design.
