Civil threaded stainless steel water pressure sensor

Product description

The piezoresistive elements of water pressure sensors made from silicon are very important because silicon is the main raw material of today's integrated circuits. The resistance of silicon is not only related to the stress-related resistance of the material itself, but also related to the stress-related geometric deformation, and can make its degree factor several hundred times larger than that of metal. The change in the resistance of N-type silicon is mainly due to the displacement of the three guide valleys, which causes the redistribution of carriers among the three guide valleys with different mobility, thus changing the mobility of electrons in the pump Pressure Sensor in different flow directions. In P-type silicon, on the other hand, the phenomenon becomes more complicated because changes in effective mass are associated with changes in the shape of the conductive valley and lead to changes in equivalent mass and hole conversion. Piezoresistively type pressure sensor is generally connected with Whiston bridge with lead wire, usually bridge in a state of balance (called zero), no external pressure on the sensitive core, when the pump pressure sensor is pressed down, the bridge will lose balance when the chip resistance changes, if the bridge plus constant current or constant voltage power supply, the sensor resistance changes through the bridge into pressure signal output; The bridge will output a voltage signal corresponding to the pressure. Specializing in the manufacture of common rail Pressure Transmitter, hydraulic pressure sensor, Water Pressure Sensor, CNG/LPG High Pressure Sensor, water purifier pressure transmitter, Urea Pressure Sensor, etc.
