HT13 Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT13 silicon pressure sensor is the latest design of oil-filled diffused silicon pressure sensor, with high pressure impact 100,000 times is not bad, and anti-interference/erosion/freezing/impact, high accuracy and stability. All stainless steel with inductive pressure film. The pressure response is faster and more sensitive. Specially designed small diameter pressure sensor,For a high quality pressure controller, the most important thing is the sensor. Adopt 316 stainless steel, high precision CNC, import seal.

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