Product Description
HT19 Hengtong Absolute Gauge Piezoresistive Silicon Pressure Sensor for water and oil
Absolute Gauge Piezoresistive Pressure Transducer Oil Water Pressure Transducer Sensor
HT19 Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT19 functions as a silicon piezoresistive pressure sensor ,with a core consisting of a highly stable diffused silicon element,. It effectively measures the pressure of liquids and gases by transmitting the pressure of the tested medium to the silicon diaphragm through an isolation diaphragm and silicon oil.The sensor's versatility finds extensive use in air compressors and refrigeration systems
Product Features of silicon pressure sensor:
- 1.Utilizing advanced technology and 316L stainless steel housing, along with materials such as titanium and Hastelloy for the diaphragm
- 2.Employing thick-film circuits for temperature compensation and zero-point correction
- 3.outstanding reliability, repeatability, and stability
Applications of silicon pressure sensor:
- 1.Suitable for measuring non-corrosive gas and liquid pressure with 316L stainless steel compatibility
- 2.Applied in various industrial process sites, including petroleum, chemical, metallurgy, power, and hydrology
- 3.Used in marine and aviation industries
- 4.Suitable for hydraulic and pneumatic control systems
- 5.Utilized in process control applications
Electrical performance of silicon pressure sensor:
- 1.Power Supply: ≤2mA DC (Typical 1.5mA DC)
- 2.Input Impedance:3KΩ~6KΩ
- 3.Output Impedance:2.5KΩ~6KΩ
- 4.Electrical Connection:Gold-plated Kovar pins or 100mm high-temperature wires.

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.
