Product Description
Hengtong HT20 Mini Differential silicon Pressure Sensor Cell for Liquid Test
HT20 Differential Pressure Sensor
Introduction of differential silicon pressure sensor:
The HT20 differntial silicon pressure senor is a silicon piezoresistive differential pressure sensor with a core of highly stable diffused silicon element. The core is enclosed in a 316L stainless steel housing, and the pressure is transmitted through a stainless steel diaphragm and sealed silicon oil to the sensitive chip. The sensitive chip does not directly contact the measured medium, forming a fully solid-state structure for pressure measurement, enabling precise measurement of differential pressure. Therefore, this product can be applied in various scenarios that require differential pressure measurement, including harsh and corrosive environments

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.
