The 4–20mA RTD PT100 SBW Temperature Sensor Transmitter Module is a high-precision temperature measurement and signal conversion module designed for industrial and automation applications. It converts the resistance signal from a PT100 RTD sensor (Single Bridge Wire – SBW) into a standard 4–20mA current output, ensuring reliable and noise-immune long-distance transmission.

With a measurement range of 0 to 100°C, this module is ideal for environments where accurate temperature monitoring, stability, and compatibility with PLCs, controllers, and industrial instruments are required.
