Product Description
HT19V Piezoresistive Silicon Pressure Sensor
Introduction of silicon pressure sensor:
HT19V The sensing package utilizes silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element. A ceramic substrate is attached to the package that contains lasertrimmed resistors for temperature compensation and offset correction. An additional laser-trimmed resistor is included which can be used to adjust an external differential amplifier and provide span interchangeability to within ±1%.
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

| Ordering tips |
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.
