ST Series Temperature Transmitter

ST series transmitter is specially designed for temperature measurement.The transmitter converts the measured temperature into an electrical signal. The electrical signal enters the A/D converter through the isolated module of the transmitter. After multi-level compensation and calibration of the data by the microprocessor, the corresponding analog or digital signal is output and displayed on the LCD module. The FSK modulation signal of the HART protocol is superimposed on the 4-20mA current loop through the modulation and demodulation module.
