Product Description

HT19F Industrial Diffusion Silicon Pressure Sensor

The HT19F silicon piezoresistive pressure sensor features a highly stable diffused silicon element core that accurately measures liquid and gas pressure. Pressure is transmitted through an isolation diaphragm and silicon oil to the silicon diaphragm, making it ideal for air compressors and refrigeration systems.

Product 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 compatible with 316L stainless steel
Industrial process sites: petroleum, chemical, metallurgy, power, and hydrology
Marine and aviation industries
Hydraulic and pneumatic control systems
Process control applications

Selection Examples

Ordering Guidelines

1. Ensure proper fit between core size and transmitter housing for required airtightness

2. Maintain vertical alignment and apply even pressure during housing assembly

3. Specify special requirements if measured medium is incompatible with 316L materials

4. Avoid contact with sensor diaphragm using hands or sharp objects

5. Keep gauge pressure port open to atmosphere and prevent contamination

6. Refer to actual core label for pin lead configurations
