Only by tasting sorrow and swallowing bitterness can a fragile heart learn to be strong. As long as you have unchanging dreams, there will be hope ahead. Passing through the years, walking day and night, this road has been bumpy and bumpy, leaving deep and shallow footsteps. Looking back at dusk, this bumpy road is a picture of life. Spring goes and autumn comes, and it will never fade.
Installation of mine damper opening and closing status sensor

Install the sensor head set on the edge of the door frame, then install the magnet assembly on the accessory, and fix it together on the edge of the damper and the sensor head Group correspondence.
Connection users can use the cables prepared in the junction box and the instrument itself to connect to the underground substation of the mine safety production comprehensive monitoring system.
Adjustment of the mine damper opening and closing status sensor

After the damper switch is installed, when the damper is in the opening state, the gap between the damper and the door frame is the alarm distance specified by the user. At this time, the user can Select the alarm distance within a certain range. It is determined by the initial position of the sensing head group and the magnet block group, so the user can flexibly install and use it according to the specific situation while ensuring the normal operation of the instrument.
A brief description of the air door opening and closing status sensor products

The mine air door opening and closing status sensor is used in conjunction with the comprehensive monitoring system for mine safety production. The sensor can also be connected to other monitoring systems. It can continuously detect the status of the air door switch set in the ventilation tunnel of the coal mine. When the damper is not tight due to various reasons, it can send a switching signal to the computer monitoring system, so that the ventilation manager can accurately know the opening and closing status of the underground damper.
Structure of mine damper opening and closing status sensor

The instrument consists of two parts: the sensing head group and the magnetic block (as shown in Figure 1). The sensing head group consists of a reed switch shell, a plug, It is composed of socket cable fixing plate, etc., and the magnetic block group is composed of magnet, shell, etc.
Principle of mine damper opening and closing status sensor

When the magnetic field intensity reaches a certain intensity, the dry reed switch will One set of contacts is disconnected from the original contact piece, and the other contact piece is attracted. When the reed switch is separated from the strong magnetic field, it returns to its original state. Using this principle, the sensor head set with the reed switch and the magnet block that generates a strong magnetic field are placed on the door frame and the edge of the door respectively. (The two are opposite) using the change of the position of the damper, the instrument can generate a switch signal, which is sent to the computer monitoring system through cables.
