SEM330 methane transmitter designed by our company uses an explosion-proof ExdIMb sensor, which has strong safety, fast response speed, and strong anti-interference ability. It has passed our unique compensation algorithm and multi-stage standard gas. Calibration also has the characteristics of long life, high precision, high repeatability and high stability. It is suitable for underground pipe corridors, underground parking lots, public toilets, garages, workshops, chemical plants, greenhouse farms and other occasions where real-time monitoring of methane concentration is required.
The equipment adopts wide-voltage 10-30V DC power supply, 485 signal output, standard Modbus-RTU communication protocol, ModBus address can be set, baud rate can be changed, and the maximum communication distance is 2000 meters.
