Vibration Instrumentation

Proximity

Our revolutionary Digital Proximity System (DPS) eliminates the need for dozens of different drivers and transmitters by a single, field-configurable package that can be set to work with probes and cables from a variety of manufacturers. The DPS consists of a probe, an extension cable, and a driver or transmitter. Download Brochure

Seismic vibration instrumentation is used to measure structural vibration on bearing housings, piping, machinery housings, and machine support structures.  It is particularly suitable for machinery with rolling-element bearings. These types of bearings will generally transmit both shaft-and bearing-related vibration to the outside of the machine where it can be detected by seismic measurements.

Switches

Electronic and mechanical vibration switches for overall vibration monitoring and trending without the necessity of complex systems. Models available with Hazardous Area Ratings and explosion-proof housing. Our state-of-the-art electronic switches are programmable to suit user needs.

Portable

Economical solutions in Meters and Shakers ideal for obtaining radial vibration casing measurements. Some rated intrinsically safe for hazardous areas.

Shakers

The Hardy Shaker ensures that the Seismic Sensors and Transmitters that you have installed are working properly and giving you the results you need.  Just like the pressure and flow instruments in your facility need calibration checks every year, so do your Seismic Sensors and Transmitters.  This system puts the calibration check of those Seismic Sensors and Transmitters within your control, and within your budget.

The most cost effective maintenance strategy is a predictive and proactive strategy, versus a preventative maintenance or run-to-failure strategy.  The entire premise of a predictive and proactive maintenance program is based on the reliability and integrity of the transducers providing the information in a timely way.  If the Seismic transducers are not working properly, you will not receive the value you are expecting in order to produce the return on investment that you have already made.  The Hardy Shaker is a necessary tool to ensure your proactive maintenance strategy is effective.

The Hardy Shaker comes in four models:  The HI-903 is our top of the line and offers onboard memory, multiple tests, automated Excel reports and new ruggedized case.  The HI-803 offers onboard memory, multiple tests, the ability to print results and the ability to download the saved data to an Excel file using the serial to USB interface cable.  The HI-913 provides the ability to conduct vibration sensor testing, the ability to change frequency without having to adjust amplitude, and a new ruggedized case.  The HI-813 provides the ability to conduct vibration sensor testing.  All Hardy Shakers are able to validate the entire vibration loop, from the transducer to the measurement system. All Hardy Shakers are traceable to NIST.
