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.

1. In the assembly, attention should be paid to the coordination of the core size and the transmitter housing to achieve the necessary tightness.
2. During the assembly of the shell, ensure that it is vertically aligned and apply pressure evenly to avoid getting stuck or damaging the compensation plate.
3. If the medium under test is not compatible with the core diaphragm and housing material (316L), special instructions should be provided when placing the order.
4. Avoid pressing the sensor diaphragm with your hands or sharp objects to avoid deformation or puncture of the diaphragm and damage to the core.
5. Keep the pressure port of the gauge pressure core open to the atmosphere to prevent water, water vapor or corrosive media into the negative pressure chamber of the gauge pressure core.
6. If there is any change in the pin, please refer to the label you actually carry.
7. Customizable, please contact the business manager to negotiate.
