Triaxial accelerometer 943

IEPEsmallconstant-current

The IRD Model 943 is a 100 mV/g seismic accelerometer designed for use with portable analyzers and data collectors. The Model 943 design is based on the proven performance of the 942 accelerometer used in permanent vibration monitoring applications. The Model 943 can be stud-mounted, used with a magnet holder or used with extension probes to measure vibration. For walk-around data collection that combines permanently installed 942 accelerometers and hand-held measurements, the Model 943 has the advantage of not needing to switch cables, input ports or transducer sensitivities. The Model 943 incorporates the industry standard IEPE constant current interface. This is a low-output impedance, constant-current driven amplifier with a lownoise floor. The wide frequency and amplitude range of the Model 943 accommodate most vibration measurement applications for predictive maintenance. The small size of the Model 943 permits its use in remote and tight spaces. All Model 943 components are designed for use in harsh industrial environments.
