Product Description
The HT19 is a high-stability silicon piezoresistive pressure sensor built around a diffused silicon element. It measures the pressure of liquids and gases by transmitting pressure through a silicon diaphragm and a silicone oil diaphragm, effectively isolating the measured medium. A precision amplifier circuit delivers a standard 0.5–4.5VDC output. Its versatility makes it widely suitable for air compressors, refrigeration equipment, agricultural irrigation systems, and level measurement applications.
- Advanced manufacturing technology with a 316L stainless steel housing; diaphragm options include titanium and Hastelloy for demanding media.
- Thick-film circuits provide reliable temperature compensation and zero-point stability.
- Outstanding reliability, repeatability, and long-term stability.
- Compact, integrated design suited to OEM and industrial integration.
- Measurement of non-corrosive gas and liquid pressure compatible with 316L stainless steel.
- Industrial process sites including petroleum, chemical, metallurgy, power, and hydrology.
- Marine and aviation industries.
- Hydraulic and pneumatic control systems.
- Process control and automation applications.
- Agricultural irrigation and liquid level monitoring systems.

| 1. Pay attention to the fit between the core size and the transmitter housing during assembly to achieve the required air tightness. |
| 2. During housing assembly, ensure vertical alignment 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 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. |
