Models covered
YMC 271A01(S) Standard Sensor uses natural quartz as the sensing element, giving good temperature characteristics, long-term stability, a shear-mode structure and an effective strain-isolation base. Bottom and top female M5 threads (10-32 optional) allow it to be used as a laboratory standard sensor for precise back-to-back comparison calibration of vibration transducers, and for vibration sensor precision calibration, testing and inspection. YMC 271A02 is the high-frequency standard sensor.
Typical applications
- Back-to-back comparison calibration of vibration transducers
- Laboratory reference standard
- Sensor precision calibration, testing and inspection
