Durable GYH25 mining oxygen sensor oxygen sensor

Mine Oxygen Sensor Oxygen Sensor
Product Introduction:
This product is a new generation of intelligent oxygen sensor. It adopts standard signal output and can be used with various domestic power outages and monitoring systems. Continuously monitor oxygen levels in flammable work environments.
It has the characteristics of long communication distance, high contact output power, local display, sound and light alarm, infrared remote control adjustment, and easy installation and use.
1. Purpose
The oxygen sensor (hereinafter referred to as the sensor) is developed to meet the needs of coal mines in my country for monitoring underground oxygen concentration. It can continuously and automatically convert the underground oxygen concentration into a standard electrical signal and transmit it to the matching equipment, and has functions such as local display of biogas concentration value and over-limit sound and light alarm. After the sensor has been online inspected by the national explosion-proof inspection agency, it can be matched with various types of domestic monitoring systems, power outages, and wind power gas locking devices. It is suitable for fixed use in coal mining working faces, mechanical and electrical chambers, return air tunnels and other locations.

3. Main features
． The use of new single-chip microcomputers and highly integrated digital circuits makes the circuit structure simple, reliable in performance, and easy to maintain and debug.
． It realizes infrared remote control functions such as zero point, sensitivity, alarm point adjustment, etc., making adjustment convenient and simple.
3. The sensor power-off control function is added, and the power-off point can be set arbitrarily, realizing one machine with multiple uses.
． The use of a new switching power supply reduces the power consumption of the entire machine and increases the transmission distance of the instrument.
． Added fault self-diagnosis function for easy use and maintenance.
． A new high-strength shell structure is designed to enhance the instrument's impact resistance.
