All-in-one revolution in strain measurement

A Sensor-Technik UK product story

It's rare to find a genuine innovation in strain measurement, but the new IVDMS from Sensor-Technik UK claims to be just that.

It's rare to find a genuine innovation in strain measurement, but the new IVDMS from Sensor-Technik UK claims to be just that.

Until now, measuring the strains in beams (such as on cranes) has been a complicated and fragile process, but this matchbox-sized unit simply has to be glued on and calibrated in software, and readings can be taken immediately.

On the face of the IVDMS is a small strain-gauge "chip" which is glued to the surface under investigation.

Around the edge of the unit is a seal, and two mounting bolts which between them provide IP65 protection for the sensors.

A CANbus link to a PC is then used to enable software setup of span and linearity and that's all there is to the procedure.

Existing metalwork does not need to be modified, as is so often the case in normal approaches, and there's no need to match up strain gauges and amplifiers from different manufacturers, with all the setup difficulties that involves.

In addition, the glued contact provides excellent accuracy.

The IVDMS has already been applied successfully in crane loading and fire engine access platform measurements, but is sure to have a wide range of applications as its potential becomes more widely known.
