HT19V Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT19V uses highly stable diffusing silicon elements, making it a
reliable silicon piezoresistive pressure sensor.By using an
isolating diaphragm and silicone oil, the sensor can accurately
measure the pressure of liquids and gases, providing precise
results.The constant voltage power supply compensates for the
temperature drift of the product, which greatly reduces the impact
of temperature changes. Its wide application in air compressors and
refrigeration systems makes it a valuable asset in various
industries.
Product Features of silicon pressure sensor:
1. The thick film circuit is used for temperature compensation and
zero offset correction.
2. High reliability, good stability.
3. Constant voltage power supply, the standard output.
Applications of silicon pressure sensor:
1. Suitable for measuring the corrosive gas and liquid pressure,
compatible with 316 l stainless steel
2. Used in process control systems to monitor and control pressure.
3. Often used in refrigeration system and air compressor pressure
measurement.
Electrical performance of silicon pressure sensor:
1.Power Supply: ≤10VDC
2.Common Mode Voltage Output: 50% of the input (typical)
3.Input Impedance:4KΩ~20KΩ
4.Output Impedance:2.5KΩ~6KΩ
5.Electrical Connection:100mm high-temperature wire,ribbon cable

1. During assembly, attention should be paid to the coordination
between the core size and the transmitter housing to achieve the
required tightness.
2. When assembling the housing, ensure that it is vertically
aligned and apply pressure evenly to avoid damaging the
compensation plate.
3. If the measured medium is not compatible with the core diaphragm
and housing material (316L), special instructions should be
provided when placing the order.
4. Avoid pressing the sensor diaphragm with your hands or sharp
objects to avoid deformation or puncture of the diaphragm and
damage to the core.
5. Keep the pressure port of the gauge pressure core open to the
atmosphere to prevent water, water vapor or corrosive media into
the negative pressure chamber of the gauge pressure core.
6. If there are any change pin, please carry according to the
actual product label for reference.
