Rapid reaction pressure sensor applied to air-conditioning refrigeration equipment

Abstract

The invention discloses a rapid reaction pressure sensor applied to air-conditioning refrigeration equipment. The rapid reaction pressure sensor applied to the air-conditioning refrigeration equipmentcomprises a sensor shell. A rear seat body is fixedly arranged at one end of the sensor shell, a rubber gasket is glued between the sensor shell and the rear seat body, an insulating sleeve is fixedly arranged at one end, far away from the sensor shell, of the rear seat body, the interior of the sensor shell is hollow, and one end of the rear seat body is inserted into the interior of the sensorshell. A conductive sheet is mounted inside the sensor shell, and a sensor chip is fixedly mounted on one side, close to the conductive sheet, of the inside of the sensor shell. According to the rapidreaction pressure sensor applied to the air-conditioning refrigeration equipment, the sensor is small in size, good in dynamic characteristic, high in temperature resistance and capable of quickly reacting to pressure, the sensor shell and the sensor chip can be quickly assembled together through an arranged assembly device, uninterrupted and continuous assembly can be realized, and the production efficiency of the pressure sensor is improved.

Description

technical field [0001] The invention relates to the technical field of pressure sensors, in particular to a quick-response pressure sensor used in air-conditioning and refrigeration equipment. Background technique [0002] A pressure sensor is a device or device that can sense a pressure signal and convert the pressure signal into an available output electrical signal according to a certain rule; the pressure sensor is usually composed of a pressure sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors; pressure sensors are the most commonly used sensors in industrial practice, and are widely used in various industrial automatic control environments, involving water conservancy and hydropower , railway transportation, intelligent building, production automation, aerospace, military industry, petrochemical, oil well, el...
