Product Description

HT-IQ 50.4mm Big Diaphragm Silicon Piezoresistive Pressure Sensor

The HT-IQ is a flush diaphragm pressure sensor featuring 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 product's flat diaphragm structure offers easy cleaning and high reliability, making it ideal for food, beverage, pharmaceutical, and hygiene applications.

Product 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
Outstanding reliability, repeatability, and stability
Flush diaphragm structure for easy cleaning and maintenance

Applications

Measuring non-corrosive gas and liquid pressure with 316L stainless steel compatibility
Food and beverage processing industry
Industrial process control systems
Pharmaceutical manufacturing and processing

Selection Examples

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

If the measured medium is not compatible with the core diaphragm and housing material (316L), provide special instructions when ordering
Avoid pressing the sensor diaphragm with hands or sharp objects to prevent damage from deformation or piercing
Keep the pressure port of the gauge pressure core open to the atmosphere and prevent entry of water, water vapor, or corrosive media
Refer to the label on the actual core for any pin lead configuration changes
