HT-IQT Silicon Piezoresistive Pressure Sensor
Introduction of silicon pressure sensor:
HT-IQT is a flush diaphragm pressure sensor with a highly stable
high temperature diffusion silicon chip. The sensitive chip does
not directly contact the measured medium. The pressure is
transferred to the sensitive chip through the stainless steel
diaphragm and the sealing silicone oil, and the resistance bridge
of the chip changes, resulting in a change in voltage, and the
voltage changes to the millivolt level. This product is high
temperature clamp structure, easy to clean will not produce
crystallization in the thread end, easy to clean, simple
installation, high reliability. Suitable for food, health and other
industries.

Electrical performance of silicon pressure sensor:- Power Supply: ≤2mA DC (Typical 1.5mA DC)
- Input Impedance : 2.5KΩ~6KΩ
- Output Impedance: 2.5KΩ~6KΩ
- Electrical Connection: Gold-plated Kovar pins or 100mm
high-temperature wires.
