Wholesaler Beam Infrared Sensor With Good Quality Traffic Loop Coil On Sale

Wholesaler Beam Infrared Sensor 

Wholesaler Beam  Infrared Sensor application vary widely.  Note: The four-beam detector has two sets of optical systems. It is necessary to cover the upper and lower lenses of the receiver separately and adjust until the upper and lower photosensitive voltage values are the same. The two sets of optical systems of the older four-beam detectors are separately adjusted. It is difficult to adjust due to the corresponding relationship between the two optical systems of the transmitter and the receiver. Special attention to detail is required, and false alarms or protected dead zones can occur if not handled properly. There is a shading time adjustment knob on the receiver, and the general shading time of the probe is 50m/s.

When the probe is shipped from the factory, we will adjust the shading time of the probe to a standard position. Under normal circumstances, this position is a relatively comfortable state, considering the environmental conditions and the characteristics of the probe itself, so there is no special The reason is that there is no need to adjust the shading time. If you want to fortify, you need to adjust the shading time to adapt to changes in the environment. In general, the shading time is short and the sensitivity of the probe is fast, but it is also very sensitive to the like leaves and flying birds. The possibility of false alarms will increase. The shading time is long, the sensitivity of the probe is reduced, and the possibility of underreporting is increased. The engineer should adjust the shading time according to the actual needs of the fortification. Anti-theft host function of infrared sensor after the probe is set, it will be tamper-proof Connect the switch to the input circuit of the zone. After the connection is completed, cover the outer casing of the probe and tighten the fastening screw. It is required that the zone warning light is not flickering or lighting on the anti-theft host. There is no alarm indication output in the zone. Indicates that the entire zone is set properly. Otherwise, the line should be tested, the probe should be re-commissioned, and the status of the zone should be re-confirmed. Wholesaler Beam Infrared Sensor Hot sale.

The routine maintenance of wholesaler Beam infrared sensor, in the daily work of the detector, due to long-term outdoor, it is inevitable to receive dust microbes and snowflakes, frost and fog in the atmosphere. For a long time, a dusty hard shell was deposited on the outside of the detector. A thick layer of canola will grow in damp areas. Sometimes the bird will pull its waste to the detector. These things will hinder the emission and acceptance of infrared signals. Causes a false positive signal. Therefore, we pay special attention to the cleaning problem of infrared radiation. It is necessary to organize it regularly.
