Product Description
HT SENSOR 19mm Silicon Piezoresistive Pressure Sensor
Advanced silicon piezoresistive pressure sensor designed for conventional pressure transmitters, featuring a 19mm form factor for precise level measurement applications.
Product Overview
The HT19F silicon piezoresistive pressure sensor utilizes a highly stable diffused silicon element to accurately measure liquid and gas pressures. Pressure transmission occurs through an isolation diaphragm and silicon oil to the silicon diaphragm, making it ideal for air compressors and refrigeration systems.
Key Features
- Advanced technology with 316L stainless steel housing

Ordering Guidelines
- 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 if measured medium is incompatible with core diaphragm or housing material (316L)
- Avoid pressing sensor diaphragm with hands or sharp objects to prevent damage
- Keep gauge pressure core port open to atmosphere and prevent entry of water, vapor, or corrosive media
- Reference actual core label for any pin lead changes
