HT26 Diffused Silicon Pressure Sensor Piezoresistive Pressure
Sensor
Introduction of silicon pressure sensor:
HT26 is A high-sensitivity piezoresistive silicon chip is built in
as the pressure-sensing element. Pressure is transmitted via an oil
filling. The upstream separating diaphragm completely isolates the
pressure chip from the medium to be measured. it easy to install.
Product Features of silicon pressure sensor:
1.Utilizing advanced technology and 316L stainless steel housing,
along with materials such as titanium and Hastelloy for the
diaphragm
2.Employing thick-film circuits for temperature compensation and
zero-point
correction
3. Outstanding reliability, repeatability, and stability
4. Height of 7mm, customizable
Applications of silicon pressure sensor:
1. Suitable for measuring non-corrosive gas and liquid pressure
with 316Lstainless steel compatibility
2. Applied in various industrial process sites, including
petroleum, chemical, metallurgy, power, and hydrology
3. Used in marine and aviation industries
4. Suitable for hydraulic and pneumatic control systems
