PLT Series CAN Bus Integrated Level and Temperature Sensor
The PLT series CAN bus integrated level and temperature sensors measure liquid level, pressure, and temperature in pressurized and open tanks (up to 1.6 MPa). The sensor consists of two parts: the sensor unit and display, connected via CAN 2.0B. The explosion-proof version meets GB3836 standards (Exib II CT5Ga) and features an OLED display, supporting range adjustments and on-site calibration.
