Product Description
19mm 10VDC powered pressure sensor for air and liquid test
HT19V Silicon Piezoresistive Pressure Sensor
Introduction:
HT19V employs a highly stable diffused silicon element, making it a reliable silicon piezoresistive pressure sensor. By utilizing an isolation diaphragm and silicon oil, the sensor accurately measures the pressure of liquids and gases,offering precise results. Its extensive applications in air compressors and refrigeration systems make it a valuable asset in various industries.
Product Features:
- Utilizes thick-film circuitry for temperature compensation and zero offset correction.
- High reliability and excellent stability .
- Constant voltage power supply, standard output
Applications:
- Suitable for measuring non-corrosive gas and liquid pressure with 316L stainless steel compatibility
- Used in process control systems for monitoring and controlling pressure.
- Commonly used in refrigeration systems and air compressors for pressure measurement.
Electrical 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.
