HT19 Piezoresistive Silicon Pressure Sensor

Introduction of 15mm silicon pressure sensor:

HT19 piezoresistive silicon pressure sensor. Its main components are silicon sensing elements with high stability.The sensing package uses silicone oil to transfer pressure from a 316L stainless steel diaphragm to the sensing element.The piezoresistive effect of diffused silicon was used to measure the air-liquid pressure.It is the most commonly used silicon sensor to measure pressure and the price is also cheaper than other types.

Electrical performance of 15mm silicon pressure sensor:

• Supply:1.5mADC
• Input impedance:3KΩ~6KΩ
• Output impedance:2.5KΩ~6KΩ
• Insulation resistance:≥100MΩ/50VDC
• Insulation voltage:500VAC between the housing and electrical connection will not cause damage
• Medium compatible: liquid, gas compatible with 316L stainless steel

Performance Specification of silicon Pressure sensor:

Note :Above parameter under condition:Supply: 1.5mA Temperature: 25℃

Dimension

1. In the assembly, attention should be paid to the coordination of the core size and the transmitter housing to achieve the required air tightness.
2. During the assembly of the shell, ensure that it is vertically aligned and apply pressure evenly to avoid getting stuck or damaging the compensation plate.
3. If the medium under test 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 is any change in the pin, please refer to the actual shipping label.
