The HT-1000 Temperature Transmitter consists of a resistance temperature detector (RTD) and a transmitter circuit module. It adopts a two-wire system, meaning a single pair of wires serves both as the power supply and signal transmission line. Equipped with a non- linear correction circuit, the HT1000 can measure temperatures ranging from -50°C to +150 °C in various industrial media.It converts the temperature signal into a linear 4–20mA DC current output, which can be transmitted to display units, controllers, recorders, or DCS systems for centralized monitoring and control.
The HT-1000 is widely used in the rail transit industry and can be integrated with analog gauges, digital displays, recorders, regulators, and DCS systems to form comprehensive temperature measurement and control systems.
