19mm Diffused Silicon Pressure Sensor Piezoresistive Pressure
Sensor
Introduction of silicon pressure sensor:
HT19 piezoresistive silicon pressure sensor, the main component is
a high stability diffuse silicon sensing element. The sensing
package utilizes silicone oil to transfer pressure from a 316L
stainless steel diaphragm to the sensing element. Piezoresistive
pressure sensor adopts international advanced silicon pressure chip
with high stability and high precision, adopts sintering base with
optimized stress design, and is produced by SMT, gold wire bonding,
diaphragm welding, high vacuum oiling, pressure cycle stress
relief, high temperature aging, temperature compensation and other
processes. With more than 30 years of development, production
experience and technological innovation, the products have
excellent stability and performance, and are widely recognized by
users.
Product Features of silicon pressure sensor:
• Rugged, isolated stainless steel package
• Small size
• Reliable semiconductor technology
• Calibrated and temperature compensated
• Absolute and gage pressures
• Vacuum compatible, isolated sensors
• Low cost
