-
Suitable to measure dynamic air gauge pressure;
- Small size, M5×0.5 mounting;
- Measurement range absolute 500kPa;
- Response time<0.1ms;
- Anti-shock>100g.
Pressure sensor AP500K, 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.
