Description

MINIATURE TRIAXIAL PIEZOELECTRIC CHARGE ACCELEROMETER, WITH SLOTS, EXCL. CABLE
Designed for simultaneous high-level measurements in three mutually perpendicular directions.

Types 4326-A and 4326-A-001 are triaxial piezoelectric ThetaShear® patented accelerometers with three independent outputs for simultaneous high-level measurements in three mutually perpendicular directions. Each transducing element is individually calibrated.

USE SCENARIOS
General purpose, multi-axis vibration and shock measurements on low-mass structures and in confined spaces

To avoid triboelectrical noise originating in the connector and to provide maximum measurement reliability and confidence, special attention has been paid to the three connectors. Both accelerometers feature three separate, rugged 10 – 32 UNF connectors.

CHARACTERISTICSThis piezoelectric accelerometer may be treated as a charge source. Its sensitivity is expressed in terms of charge per unit acceleration (pC/g).

The ThetaShear design involves a slotted cylindrical stanchion holding a central seismic mass, flanked by two piezoelectric plates. This assembly is clamped rigidly by the cover. To ensure optimum accuracy and reliability, no bonding agent other than molecular adhesion is required to hold the assembly together. The ThetaShear design provides a combination of highest measurement stability, excellent sensitivity-to-weight ratio and low sensitivity to extraneous environmental effects.

A remarkable feature of the ThetaShear principle is the fact that the transverse resonance frequency will always be found outside the 10% frequency limit.
