Smart 4-20mA Head Mounted Temperature Transmitter with Universal Input
Instruction
WNK621 4~20mA two-wire integrated circuit board is specifically designed for intelligent temperature transmitters. With microprocessor as the core of its highly-integrated circuit, it reliably achieves thermal resistance/thermocouple signal acquisition, processing and loop output, and also provides single bus digital interface and dedicated configurator to achieve full digital debugging and calibrating. it particularly well-suited for producing and manufacturing two-wire intelligent temperature transmitters.
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
- Single wire communication interface, dedicated configurator debugging
- Unique output migration, reverse function
- Highly integrated, Anti-jamming design and Hardware and Software watchdog
