HT20V Diffused Silicon Pressure Sensor 10VDC Piezoresistive Differential Pressure Sensor Cell
HT20V 10VDC Differential Diffused Silicon Pressure Sensor for differential pressure test
Introduction of differential diffused silicon pressure sensor:
HT20V is a differential pressure sensoris a differential pressure sensitive device isolated by stainless steel double corrugated diaphragm. Precise measurements are achieved by isolating the diaphragm and filling the silicone oil to the silicon pressure sensitive element. The sensor adopts the international advanced silicon pressure chip with high stability and high precision, and adopts the sintered base designed by stress optimization. The production process of the sensor includes: patch, gold wire bonding, film welding, high vacuum oil injection, pressure circulation stress relief, high temperature aging, temperature compensation, etc. The shape, size and sealing method of the general products are consistent with the international mainstream products of the same kind, and the interchangeability is good. They are widely used for differential pressure and level measurement in 316L stainless steel compatible media.

2. During the assembly of the housing, ensure it is aligned vertically and apply even pressure to avoid jamming or damaging the compensation plate.
3. If the measured medium is not compatible with the core diaphragm and the housing material (316L), special instructions should be provided when placing the order.
4. Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage to the core due to diaphragm deformation or piercing.
5. Keep the pressure port of the gauge pressure core open to the atmosphere and prevent the entry of water, water vapor, or corrosive media into the core negative pressure chamber.
6. If there are any changes to the pin leads, follow the label on the actual core for reference.
