Pressure Sensor
Key Words：Pressure Sensor
The pressure sensor is the most widely used sensor. Traditional pressure sensors are mainly mechanical structure devices, and use the deformation of elastic elements to indicate pressure. However, this structure is large in size and heavy in mass, and cannot provide electrical output. With the development of semiconductor technology, semiconductor pressure sensors have also emerged. Its characteristics are small size, light weight, high accuracy and good temperature characteristics. Especially with the development of MEMS technology, semiconductor sensors are developing towards miniaturization, with low power consumption and high reliability.

Pressure Sensor Parts
Key Words：Ceramic pressure sensor chip SMT OEM service


The function of the pressure sensor is usually to convert the measured non-electricity into an electrical output. It mainly consists of four parts: the sensitive component, the conversion component, the measurement circuit and the auxiliary power supply.

1. Sensitive element: In a load cell, the main function is to sense the change in the measurement value, and at the same time convert the measurement value into an intermediate variable that is easy to convert into electricity. For example, diaphragm pressure sensors, whose sensitive component is an elastic diaphragm, whose function is to convert the pressure signal into the deformation of the diaphragm in preparation for outputting the next electrical signal.

Pressure Transducer
Key Words：Compressor pressure transducer Hydraulic pressure transducer
Pressure transducer is the most commonly used sensor in industrial practice. It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships , machine tools, pipelines and many other industries. There are two types of pressure transmitters: electric and pneumatic. The electric unified output signal is DC signal such as 0~10mA, 4~20mA or 1~5V. The pneumatic unified output signal is a gas pressure of 20-100Pa. Pressure transmitters can be divided into force (torque) balance type, capacitive type, inductive type, strain type and frequency type according to different conversion principles. The following briefly introduces the principle, structure, Knowledge of use, maintenance and calibration.
