Pressure sensor is an important part of pressure detection system, by all sorts of pressure sensitive element will be measured pressure signal is converted into easy to measure the electrical signals as output, to display instrument shows pressure value, or for the use of control and alarm.
A wide range of pressure sensors, piezoresistive pressure sensor, strain type pressure sensor, piezoelectric pressure sensor, capacitive pressure sensors, pressure magnetic type pressure sensors, resonant pressure sensor and differential transformer type pressure sensor, optical fiber pressure sensor, etc.
Pressure sensor is used in industrial production * to a wide range of a sensor that is mainly used in water conservancy and hydropower, railway transportation, intelligent buildings, production control, aerospace, military industry, petrochemical, oil, electric power, ships, machine tools, pipe, and many other industries.
Pressure sensor in the main use of piezoelectric materials include quartz, sodium potassium tartrate and ammonium dihydrogen phosphate.
The quartz (
Is a kind of natural crystal, the piezoelectric effect is found in the crystal, within certain limits of temperature, the piezoelectric properties have always existed, but after the temperature exceeds the range, the piezoelectric properties completely disappear,
The high temperature is called the Curie point)
Due to the changes as the change of stress field of tiny (
Also say, piezoelectric coefficient is low)
, so is gradually replaced by other piezoelectric crystal quartz.
And sodium potassium tartrate has great sensitivity and piezoelectric piezoelectric coefficient, but it can only be at room temperature and low humidity environment to the application.
Ammonium dihydrogen phosphate belongs to artificial crystal, able to bear high temperature and high humidity, so has been widely used.
In addition to the above products, the company also supplies have pt100 temperature sensor
, temperature transmitter, and other products, our company has * have practical technology, professional operation team, to create on the premise that the user experience for your service, the service of the supreme good to beauty is our endless pursuit.
