Diffused silicon oil filled sensor Diaphragm differential pressure sensor
Introduction:
HT20V is a differential pressure sensor utilizing a highly stable diffused silicon element as its core. Encased in a durable 316L stainless steel housing, the sensor operates with exceptional reliability. Pressure transmission occurs through a stainless steel diaphragm and a sealed silicon oil, ensuring precise measurements by the sensitive chip. The sensitive chip remains isolated from direct contact with the measured medium, establishing a fully solid-state structure for accurate differential pressure measurement. Consequently, this versatile product is suitable for diverse applications that demand reliable and precise differential pressure measurement.

|
1. Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the
required airtightness
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.
