  • Brand Name: WS


Product description:
1. This product is a high sensitivity pressure sensor; Using diffusion silicon pressure sensor chip, using machinery method to form a huis bridge for the chip, the signal is amplified on a slice of epoxy PCB circuit boards with the same encapsulation method, and the interface circuit is integrated together, with advantages of small size, high precision, high reliability, high cost performance, etc. And it has provided digital temperature compensation of the whole temperature range and reduce noise. So as to ensure the accuracy of the sensor to apply cars' bad working environment and therefore it is widely used in Auto intake pressure test system.

2. Application field and characteristics
Auto intake pressure testing system
Air pressure measurement field

The piezoresistive type integrated silicon pressure sensor
