Non-contact Coal Mine Underground Mining Water Level Gauge Mining Ultrasonic Level Gauge Level Sensor Details Micro-electric 1*5/0-5*3/7*5-3*6-2*8
Non-contact Coal Mine Underground Mining Water Level Gauge Mining Ultrasonic Level Gauge Level Sensor is a common device for measuring liquid level, and its uses are relatively wide. The mining ultrasonic level gauge has the characteristics of convenient installation and non-contact measurement, and is not affected by the viscosity and transparency of the liquid. At the same time, because the ultrasonic level gauge propagates through air, the measurement accuracy is affected by ambient temperature, ambient humidity, medium temperature, medium pressure, wind speed, etc.
The mining intrinsically safe ultrasonic level gauge has high measurement accuracy, easy installation and maintenance, and can simultaneously measure water level, water level difference, and flow rate, etc. It also has features such as a computer standard RS-485 interface, so it is increasingly widely used. The basic principle of ultrasonic level measurement is: the ultrasonic pulse signal emitted by the ultrasonic probe propagates in the gas, and is reflected when it encounters the interface between air and liquid. After receiving the echo signal, the round-trip propagation time of the ultrasonic wave is calculated, and the distance or liquid level height can be converted.
The main features of the mining intrinsically safe ultrasonic level gauge are:
1. Strong anti-interference, relatively small impact from the environment, can work stably in coal mines underground and measure and output accurately.
2. Strong safety and reliability. When non-contact measuring toxic, corrosive, pressurized, flammable, explosive, volatile, or leaking liquids, no valves, connecting pipes, or joints are used, there are no leak points, and it does not contact the liquid and gas in the tank, making it very safe. Even in the event of instrument damage or maintenance, there is absolutely no possibility of causing leakage, poisoning, or explosion.
3. Simple structure, small size, light weight, easy to install, maintain, and service.
4. High reliability and durability. There are no mechanical moving parts in the sensor and instrument, and they are strictly sealed and isolated from the outside, so they will not wear or corrode.
5. The power can be adjusted to adapt to different working environments.
