Description

The TST200 is a 1-Wire PT100 temperature transmitter specifically designed to connect PT100 temperature sensors to 1-Wire Master devices. The TST200 allows PT100 sensors to be added to 1-wire temperature monitoring systems over the full -200 to +850°C temperature range. The transmitter integrates a high-precision 24-bit analogue to digital converter along with advanced digital signal processing, providing accuracy and stable performance without drift over time.

The PT100, a Resistance Temperature Detector (RTD), is a widely utilised temperature sensor in industrial applications. It can be connected using 2, 3, or 4 wires, with the accuracy of the measurement increasing with the number of wires used, particularly over longer distances. The TST200 is equipped with two RJ11 connectors, simplifying the daisy-chaining of devices on a 1-Wire bus.
