for use with Accelerometers


 

With its small size and rugged electrical connector, this transducer is designed for use in laboratory testing, modal studies and vibration testing for engine and turbine monitoring, mining engineering, and many other test/measurement and industrial environments.  Its low output, combined with the ability to drive high load capacitance, permits long runs of low-cost cable without degradation of data.

The Model ACL3 features high natural frequency, a wide frequency range, and a flat sensitivity vs. temperature response over the entire temperature range.  Since the unit has low internal damping, there is also very low phase shift over the operating frequency range.

The seismic element is mechanically isolated from the mounting base, so the ACL3 exhibits low strain sensitivity.  All materials are nonmagnetic, which results in a very low magnetic-field susceptibility.  These feature, together with a sealed enclosure of welded 316 Stainless Steel, ensure accurate, reliable data under the toughest conditions.

A 1/4-28 UNF mounting hole is provided for easy installation.
