Sound and Vibration Instrument Hire and Calibration

Accelerometer Hire


 

Certified piezoelectric accelerometers and vibration monitoring equipment, supplied by the leading manufacturers and available for hire now.

 
Bruel & Kjaer 4370 accelerometer

All our accelerometers, vibration meters, etc., are delivered with current calibration certificates, traceable to UKAS. Our ISO 9001 laboratory is audited by British Standards and we are Sponsor Members of the Institute of Acoustics.

We are an independent organisation with over 40 years experience of sound and vibration solutions.

Hire is the cost effective solution with overnight access to the latest and best instrumentation.

There are two main types of accelerometer, the traditional piezoelectric [PE] charge accelerometer and the Line Drive type, sometimes called ICP, DeltaTron, Isotron, Constant Charge Line Drive [CCLD] or other trade names. The official name for these types is IEPE = Integrated Electronic Piezo-electric and because of the internal electronics the analysis equipment must include suitable power supplies - further information.

Accelerometer are fairly robust but the cables are easily damaged, so please take care.

We also have B&K UA 0599 accelerometer filters available.

To convert the sensitivities from g to ms-2 use the relationship : 1 g = 9.81 ms-2

Metra Accelerometers


Metra KS76 : Accelerometer Kits - IEPE Line Drive type £ 4 a day *

Metra KS76 Accelerometer Metra KS 76 are general purpose IEPE - Integrated Electronic Piezoelectric accelerometers, supplied with a range of accessories: also know as ICP or Integrated Circuit Piezoelectric - see the above notes.

Ideal for use with a B&K 2250 meter which has built-in engineering units and can be supplied with the FFT option for narrow band analysis - Metra KS 76 details



 

Vibration Measurement using a Sound Level Meter

Sound level meters can also be used to measure vibration if the microphone can be replaced with an accelerometer. To measure low frequency vibration the meter should have a Linear or Flat setting or include the appropriate filters

The B&K 2250 has built-in engineering (vibration) units and can be supplied with the FFT option for narrow band analysis.

If you already own a suitable meter, order a B&K JJ 2615 or a Nor 1447 preamplifier input adaptor and a B&K accelerometer to make vibration measurements using a Sound Level Meter.
