4-20ma Smart Pt100 Pt1000 Head Mounted Temperature Transmitter With Rtd, Thermocouple Input
Quick Information
WNK65 and WNK621 are recommended in application requiring amplification of RTD or T/C signals to carry to a long distance or guard against heavy field electrical noise. The transmitter converts various input to an analog signal for direct interface with Indicators, recorders, controllers, PLC, DCS, systems can be used for a wide range of applications in process control, automatic machinery and hydraulic or pneumatic system.
