Mini 0.5-4.5Vdc Output Silicon Pressure Sensor For Industrial Pressure Test

HT19-0.5-4.5V Pressure Sensor

Introduction of silicon pressure sensor:

HT19 is a silicon piezoresistive pressure sensor consisting of a highly stable diffused silicon element. It effectively measures the pressure of liquids and gases by transferring the pressure and isolating the measured medium through a silicon diaphragm and a silicone oil diaphragm. A standard 0.5-4.5VDC voltage is output through a sophisticated amplifier circuit. The versatility of the sensor is widely used in air compressors and refrigeration equipment.

Product Features of silicon pressure sensor:

• Utilizing advanced technology and 316L stainless steel housing, along with materials such as titanium and Hastelloy for the diaphragm .
• Employing thick-film circuits for temperature compensation and zero-point.
• outstanding reliability, repeatability, and stability.

Applications of silicon pressure sensor:

• Suitable for measuring non-corrosive gas and liquid pressure with 316L stainless steel compatibility.
• Applied in various industrial process sites, including petroleum, chemical, metallurgy, power, and hydrology
• Used in marine and aviation industries.
• Suitable for hydraulic and pneumatic control systems
• Utilized in process control applications.

1. Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the

required air tightness

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.
