Works with hydrostatic level sensor measuring principle: When the measured liquid level transmitter into a certain depth in, the pressure on the liquid level sensor welcome formula: Ρ = ρ.gH + Po formula: P : welcome level transmitter pressure on ρ: Measuring liquid density g: the local acceleration of gravity Po: atm H on the surface: the transmitter into the depth of the liquid at the same time, the pressure of the liquid steel is introduced into the sensor through the air guide positive pressure chamber, the negative pressure chamber and the atmospheric pressure Po and then the liquid level sensor is connected to the back of the sensor offset Po, the pressure measured by the sensor as: ρ.gH, obviously, by taking the pressure P measured liquid level sensor, get level depth. Ultrasonic level sensor performance characteristics of ultrasonic level sensor is a common inspection equipment, which has been widely applied in many industries industry, electronics, machinery, electric power, shipbuilding, chemicals and so on. We use the time for ultrasonic level sensor performance ultrasonic level sensor must be mastered, which users use is very important. Here one hundred as a technological Xiaobian for everyone to introduce specific performance characteristics of ultrasonic level sensor liquid level sensor manufacturers, hoping to help to you. (1) operating frequency. The operating frequency is the resonance frequency of the piezoelectric wafer. When the resonance frequency of the AC voltage applied to its both ends is equal to the frequency and the wafer level sensor network, the maximum energy output, the highest sensitivity. (2) operating temperature. Due to the Curie point of the piezoelectric material is generally relatively high, especially when the use of diagnostic ultrasound probe power is small, so relatively low operating temperature, can work long hours without causing failure. Medical ultrasound transducer temperature is relatively high, requiring a separate cooling device. (3) sensitivity. Depends mainly on manufacturing wafer itself. Electromechanical coupling coefficient, high sensitivity; conversely high quality liquid level sensor, low sensitivity. Ultrasonic transducer, a composite vibrator is flexibly fixed to the base. The vibrator is a composite resonators and, by a metal plate and a piezoelectric ceramic bimorph element consisting of a combination of vibrator. The resonator is conical, in order to efficiently radiate the ultrasonic waves generated by the vibration, and ultrasonic waves can be effectively gathered in a central portion of the vibrator. Outdoor uses ultrasonic sensors must have a good seal to prevent dew, rain and dust. The piezoelectric ceramic is fixed to the inside top of the metal box body. Base is fixed at the open end of the box body and covered with resin. On ultrasonic sensors for industrial robots, the requirements to achieve an accuracy of 1mm, and has a strong ultrasonic radiation.
