HT24 Flush Diaphragm Pressure Sensor with Highly Stable Diffused Silicon Sensor Chip
Product Overview
The HT24 Silicon Piezoresistive Pressure Sensor features a flush diaphragm design with a highly stable diffused silicon chip. Pressure is transmitted to the sensitive chip through a stainless steel diaphragm and sealed silicon oil, ensuring the sensitive chip never directly contacts the measured medium. This flat diaphragm structure provides easy cleaning and high reliability, making it ideal for food, beverage, pharmaceutical, and hygiene applications.
Key Features
- Advanced technology with 316L stainless steel housing and premium diaphragm materials including titanium and Hastelloy
- Thick-film circuits for precise temperature compensation and zero-point correction
- Exceptional reliability, repeatability, and stability
- Flush diaphragm structure for easy cleaning and maintenance
Applications
- Measurement of non-corrosive gas and liquid pressure with 316L stainless steel compatibility
- Food and beverage processing industry
- Industrial process control systems
- Pharmaceutical manufacturing

Ordering Tips
- Ensure proper fit between core size and transmitter housing during assembly to achieve required airtightness
- During housing assembly, maintain vertical alignment and apply even pressure to avoid jamming or damaging the compensation plate
- Provide special instructions when ordering if the measured medium is not compatible with the core diaphragm and housing material (316L)
- Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage from deformation or piercing
- Keep the pressure port of gauge pressure cores open to atmosphere and prevent water, water vapor, or corrosive media from entering the negative pressure chamber
- Refer to the label on the actual core for pin lead configuration
