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.
