ST500 temperature transmitter

The KFG sensor ST500 series PT100 resistance temperature transmitter is directly installed in the Pt100 platinum resistance junction box (forming a thermal resistance integrated temperature transmitter with platinum resistors of different structural forms) to convert the resistance signal of the thermal resistance Pt100 into a two-wire 4-20mA output.
The Pt100 temperature transmitter is used when the Pt100 platinum resistance signal needs to be transmitted over a long distance, there is a strong interference source present on site, or the signal needs to be connected to the DCS system. The platinum resistance temperature transmitter adopts a double-layer circuit board structure, with the lower layer being the signal conditioning circuit and the upper layer defining the sensor type and measurement range
The transmitter is assembled with imported British thermometer transmitter components, maintaining the same circuit, manufacturing process, structure, and performance as the original temperature transmitter.

There is a power polarity reverse connection protection circuit, which provides protection for the circuit when the output wiring is reversed (at this time, the circuit current is zero); Incorrect wiring of sensors, whether at high or low limits, will cause the transmitter output to saturate; The product has RFI/EMI protection, which is beneficial for improving the stability of measurement
