Overview

The single axis piezoelectric accelerometer QS605 consists of a triangular shear accelerometer, a charge converter, and an integral amplifier. Compared with the dynamic coil sensor, it has the advantages of small size, light weight, high reliability, wide frequency band, and can be installed in any direction. Especially, the displacement of the measurable vibration is much larger than that of the dynamic coil sensor, reaching about 10mm (depending on the sensitivity, the lower the sensitivity, the larger the displacement). It has a large output signal, good anti-interference performance, does not require an external power supply, and can be used in harsh environments such as smoke, oil and gas, and water and gas.

Uniaxial piezoelectric accelerometer QS605

Based on the piezoelectric effect of piezoelectric crystals. When certain crystals are deformed by force in a certain direction, polarization phenomena occur inside them, and opposite sign charges are generated on their two surfaces; When the external force is removed and returns to a non charged state, this phenomenon is called the "piezoelectric effect", and crystals with the "piezoelectric effect" are called piezoelectric crystals. Commonly used piezoelectric crystals include quartz, piezoelectric ceramics, etc
