GQY-RS Mining Explosion-proof Level & Temperature Sensor

Mining Level Instruments

Product Overview

The instrument adopts a combined design of a magnetic position sensor and a temperature sensor, providing wide applicability. Equipped with a high-precision conversion circuit and a 4-digit LED display, it converts the measured level and temperature parameters into an RS485 output signal for system monitoring, regulation, and control, enabling broad application.

The instrument is designed and manufactured with a stainless-steel flameproof enclosure in strict accordance with GB/T 3836 standards. The explosion-proof marking is Ex db I Mb.
