CRY441 is a miniature charge-type uniaxial acceleration sensor with a side-end output of 10-32 UNF. It is installed on an object by an M3-to-M5 bolt. It can be used for measuring tiny motions in laboratories and scientific research, and also for online monitoring of the vibration state of industrial equipment. CRY441 can be matched with armored shielded cables to measure vibration parameters such as acceleration, velocity, and displacement under strong interference conditions such as in industry and power.
