Product Description
19mm Dia Pressure Sensor Core for Industry Transmitter Level Sensor
19mm Silicon Piezoresistive Pressure Sensor designed for industrial transmitters and level sensing applications.
Product Introduction
The HT19F is a silicon piezoresistive pressure sensor featuring a highly stable diffused silicon element core. It accurately measures liquid and gas pressure by transmitting the tested medium's pressure to the silicon diaphragm through an isolation diaphragm and silicon oil. This versatile sensor is widely used in air compressors and refrigeration systems.
Key Features
- Advanced technology with 316L stainless steel housing
- Premium diaphragm materials including titanium and Hastelloy
- Thick-film circuits for temperature compensation and zero-point correction
- Exceptional reliability, repeatability, and stability
Applications
- Measurement of non-corrosive gas and liquid pressure with 316L stainless steel compatibility
- Industrial process sites including petroleum, chemical, metallurgy, power, and hydrology
- Marine and aviation industries
- Hydraulic and pneumatic control systems
- Process control applications

Ordering Tips
- Ensure proper fit between core size and transmitter housing for required airtightness
- During housing assembly, maintain vertical alignment and apply even pressure to avoid damaging the compensation plate
- Provide special instructions when ordering if the measured medium is incompatible with 316L diaphragm material
- Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage
- Keep gauge pressure core ports open to atmosphere and prevent entry of water, vapor, or corrosive media
- Refer to actual core label for any pin lead changes
