Product Details
RTD PT100 4-20mA Head Mounted Temperature Transmitter with English Calibration Software
Instruction
WNK623 4~20mA two-wire integrated circuit board is specifically
designed for intelligent temperature transmitters. With the
highly-integrated circuit cored with microprocessor, it reliably
achieves PT100 thermal resistor signal acquisition, processing and
loop output, and also provides single bus digital interface and
dedicated configurator to achieve full digital debugging and
calibration. it particularly well-suited for producing and
manufacturing two-wire intelligent temperature transmitters.
