4-20mA Industrial Stainless Steel 316L Piezoresistive Diffused Silicon Pressure Transmitter with PCB Board Pressure Sensor
HT19F silicon pressure sensor
Introduction:
HT19F pressure sensor uses the HT series silicon piezoresistive oil core developed by our company as the signal measuring element, and the signal processing circuit is located in the stainless steel housing. Convert the sensor signal to a standard output IIC signal. After strict testing and aging screening, the product has stable and reliable performance.

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.
