AcSoft - Human Vibration

Human Vibration

Vibration affects us in a variety of ways, from annoyance when the underground train rattles the china, to damage caused by extended exposure to machinery in the workplace. In a sense, the measurement requirements are very similar to workplace and environmental noise, but human vibration measurement is still regarded by many as a black art.

To solve this problem, we now offer a comprehensive range of equipment for measuring hand/arm and whole-body vibration, so assessments are no more difficult than noise surveys.

Whole-Body Vibration

In this field, there are three types of measurement – occupational exposure, annoyance and building damage.

For all three applications, we offer the Svan 958, which is a triaxial instrument measuring in X,Y and Z simultaneously.

Frequency weightings are standard for BS6472 and ISO8041 requirements, and we offer complete kits including ‘whoopee cushion’ seat pads or high sensitivity

accelerometers with responses down to 1Hz.

Measurement parameters include PPV and VDV.

The 958 is an amazingly powerful instrument for a hand-held format, and you can also measure noise at the same time in the 4th channel.

Hand/Arm Vibration

Vibration white finger is becoming a serious problem in industries where power tools are used, such as mining and metal fabrication.

The EC Physical Agents Directive defines the limits for whole-body or hand/arm vibration,with tough measurement procedures.

Once again, the 958 is equipped with a specialised triaxial hand/arm transducer, with a choice of three mounting adapters.

Now it’s quick and easy to comply with the standards, and compare results with a built-in dose calculator

Transducer Kits

We offer a choice of transducer sets for either whole-body or hand/arm vibration measurements, from Dytran.

For hand/arm vibration, the SV50 includes the 3023M2 triaxial accelerometer, and comes with three different mounting adapters, according to your application.

For seat vibration, there’s the SV39A/L ‘Whoopee Cushion’, which has the advantage of a removable transducer, which makes field calibration possible.
