Brake pressure sensor
Overview
Braking is directly related to traffic safety. Since January 1, 1988, China has stipulated that all cars must use a dual-circuit braking system. In order to measure the air pressure change of the brake system, the response time of the brake system, and evaluate the performance of safety equipment such as ABS (Anti-lock Braking System) and ESP (Electronic Stability System) onboard, NE developed a brake pressure sensor that uses an OEM pressure sensor with a stainless steel isolation diaphragm as the signal measurement element, and has been automatically tested by a computer. The laser resistance trimming process is used for zero point and sensitivity temperature compensation in a wide temperature range. It has the advantages of strong anti-interference and impact resistance, and high measurement accuracy. The whole component is made of 304/316 stainless steel, and the structure is small and compact. It is an ideal pressure measurement sensor in the field of vehicle testing.
Main features:
- Easy to disassemble
- Adopt diaphragm isolation technology
- Integrated chip
- Strong anti-interference ability, anti-lightning strike
- Multiple protection measures: current limit protection, voltage limit protection, reverse connection protection
- High precision, low temperature drift, fast response speed, impact resistance
- Strong versatility: It can be adapted to mainstream models on the market and accept customization by adapting the through nut
