Product Description
Mini 0.5–4.5VDC Output Silicon Pressure Sensor for Industrial Pressure Testing — Model HT19
The HT19 is a silicon piezoresistive pressure sensor built around a highly stable diffused silicon element. It measures the pressure of liquids and gases by transferring pressure through a silicon diaphragm and a silicone oil diaphragm, effectively isolating the measured medium. A standard 0.5–4.5VDC voltage output is delivered via a sophisticated amplifier circuit. Its versatility makes it widely used in air compressors and refrigeration equipment.
- Utilizes advanced technology with a 316L stainless steel housing, plus titanium and Hastelloy options for the diaphragm.
- Employs thick-film circuits for temperature compensation and zero-point adjustment.
- Delivers outstanding reliability, repeatability, and long-term stability.
- Suitable for measuring non-corrosive gas and liquid pressure compatible with 316L stainless steel.
- Applied across industrial process sites including petroleum, chemical, metallurgy, power, and hydrology.
- Used in marine and aviation industries.
- Ideal for hydraulic and pneumatic control systems.
- Utilized in process control applications.

- Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the required air tightness.
- During housing assembly, ensure it is aligned vertically and apply even pressure to avoid jamming or damaging the compensation plate.
- 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.
- Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage to the core due to diaphragm deformation or piercing.
- 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.
- If there are any changes to the pin leads, follow the label on the actual core for reference.
