Notes on procurement and installation of pressure transmitter
In the introduction of related knowledge of pressure transmitter, we know that the pressure transducer is mainly a measuring instrument which changes the physical pressure parameters such as gas, liquid and so on into the standard electric signal through the pressure sensor.

Working principle and measuring method of common air conditioner temperature sensor
First of all, talk about an air temperature sensor - expansion sensor: according to the object expansion and contraction principle. According to the physical form is divided into solid expansion and expansion of the liquid two kinds of temperature sensor, a mercury thermometer is the mercury liquid thermal properties of temperature measurement

The difference between ultrasonic level gauge and radar level gauge
We see the acoustic wave frequency exceeds 20kHz called ultrasonic, ultrasonic is a kind of mechanical wave, which is a mechanical vibration propagation in elastic medium, it is characterized by high frequency and short wavelength, the diffraction phenomenon of small, also can become a good direction, ray and directional spread.
