Level sensors are widely used in the automatic control of hydropower stations. A large number of systems in Daxia Hydropower Station need to use level sensors to realize monitoring, control and other functions. For a long time, the detection and calibration of the level sensor has been a troublesome problem; the function of the level sensor is to detect the oil level of the leaking oil tank. When it fails and needs to be replaced, personnel can only go to the site to install it to determine whether the sensor can be used. , the installation space is narrow, time-consuming and labor-intensive, once there is a problem with the installed sensor, a lot of time will be wasted; and because of the location of the leaking oil tank, it is difficult to determine whether there is an error in the sensor value through actual on-site measurement.

However, the detection device of the ordinary level sensor only detects the one-way state of the level sensor, and can only detect the state of horizontal displacement. The sensing range of some level sensors is fan-shaped, and the one-way monitoring device cannot be used very well. The explanation shows the damage degree of the level sensor, and the detection result is relatively simple, so we propose an automatic level sensor detection device.
