HT26V Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT26V silicon pressure sensor is a kind of piezoresistive type, its core is the spread of the highly stable silicon crystal components.The pressure difference of the measured medium is transferred to the silicon diaphragm through a 316L isolation diaphragm and sealed silicone oil.Custom structures are made from a conventional diameter of 19mm and are highly customized, with stainless steel parts available as low as 7mm.5-10V constant voltage power supply, regular output.HT26V pressure sensor is equipped with o-rings, used for pressure seal, convenient installation.
