GWD160K Series Mining Explosion-Proof Temperature Transmitter
The GWD160K series mining explosion-proof temperature transmitter uses a high-precision platinum resistance sensor for accurate temperature measurement. It provides measurement, conversion, display, and control with a (4-20) mA output and two independent switches. The OLED display supports multiple units, and parameters can be set via the front panel and automatically saved, enhancing automation and control in mining equipment.
