-
Suitable to measure dynamic air gauge pressure during side collision car crash tests;
- Small size, easy to mount;
- Measurement range 50kPa, over load 150%;
- Response time<0.1ms;
- Anti-shock>100g.
Pressure sensor DP50K, based on piezo resistance effect, zero at ambient, includes a full bridge circuit. There is resistance changed by measuring different air pressure, then the voltage signal can be converted according to the resistance difference. The reasonable MEMS process makes the sensor good linearity performance and stability. The sensor includes wear-resisting cable with default length 8m. The LEMO connector and Dallas ID are optional.
