Product Details
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.
Features
- Two-wire work mode
- Pt100,Cu50,Cu100, Pt1000 Four thermal resistance full measurement range
- K, S, R, B, N, E, J, T Eight thermocouples full range measurement
- Cold end automatic compensation
- Thermal resistance three-wire measurement automatically eliminating the lead resistance
- Thermal resistance/ Thermocouple disconnection fault prompts and output processing;
- Independent setting for temperature transmission output range
- High accuracy, low temperature drift
