Problems solved by technology

When the pressure sensor base is produced, it is usually fixed and sealed by sintering the glass insulating sleeve. When the vent tube is sintered, the glass solution will easily block the vent hole after the glass sleeve melts, which will affect the working accuracy of the pressure sensor.

Abstract

The invention discloses a pressure sensor base with good pressure resistance. The pressure sensor base is characterized by comprising a hexagonal plate, wherein a connecting column is fixedly connected with the center of the upper side of the hexagonal plate; an annular groove is formed in the upper side edge of the hexagonal plate; a sealing gasket is connected in match inside the annular groove;a first groove is formed in the center of the upper side of the column; and a vent hole, four first counterbores and an oil injection vertical hole are formed in the bottom of the first groove. The pressure sensor base has the advantages that an electrode channel is of a V-shaped structure, and when the pressure sensed by a pressure sensor exceeds working pressure, the direction of the pressure of an electrode can be changed inside an electrode channel, so that the pressure resistance of the pressure sensor base can be improved, an air inlet tube and the vent hole can be very well sealed, thevent hole is not blocked in the sintering process, and the finished product rate of the pressure sensor base can be increased.

Description

technical field [0001] The invention relates to the technical field of sensor bases, in particular to a pressure sensor base with good compressive strength. Background technique [0002] The structure of the pressure sensor is mainly composed of two parts, of which the base is one of its key components. The insulation resistance, withstand voltage, sealing, bonding performance, and pressure resistance of the sensor are all supported by the base. When the pressure sensor base is produced, it is usually fixed and sealed by sintering the glass insulating sleeve. When the vent tube is sintered, the glass solution will easily block the vent hole after the glass sleeve melts, which will affect the working accuracy of the pressure sensor. [0003] When the pressure sensor is working, it is generally used to measure the pressure. When the pressure reaches the set value of the sensor, an alarm signal is transmitted through the electrode. The pressure sensor generally has its working ...
