Customised sensor solutions often cheaper than conversions

What does not fit is made suitable

In special machine construction or when converting, upgrading or retrofitting existing machines and systems, commercially available sensors often do not fit in the intended position. This can be remedied by a service from sensor specialist burster: in the MySensor department, all force, torque, displacement and pressure transducers from the portfolio can be customised or redesigned according to the user's specifications. It sounds expensive, but it is usually cheaper than converting the systems themselves for the use of standard sensors. The procedure also saves time and guarantees optimum measured values. The conversion begins with a feasibility analysis in which CAD data is evaluated. If necessary, the sensor experts inspect the device via video to find the best possible location for force or torque measurement and then agree on the procedure. After the analysis, a prototype is produced, tested and evaluated by the user and then manufactured in series. Aluminium or stainless steel are available as materials. They cover a wide range of application requirements and are suitable for special requirements in areas such as hygiene or medical technology. If required, strain gauges can also be integrated directly into customer parts to absorb forces.

Customised design more economical - how is that possible?

Customised designs are cost-intensive and therefore undesirable. However, it is often sufficient to adapt the sensor design in order to avoid a mechanical conversion of the machine. This saves time and money. Although the range of possibilities is wide: cabinet variations with a different inner or outer diameter, shoulders or flanges or recesses on the cabinet, modified (through) holes for countersunk screw heads are sufficient in some applications for the sensor to fit. Sometimes fully encapsulated sensor bodies are required to prevent the ingress of foreign particles during injection moulding (Fig. 2). One example can be found in motor vehicles, where a sensor with a particularly flat design is required for force measurement on the control pedal. But even more complicated applications can be quickly realised with MySensor. Determining the centre of gravity of a crane boom truck requires insensitivity to vibration and impact as well as integrated low-power electronics and maximum reliability thanks to a fully encapsulated, laser-welded design. The insensitivity to lateral loads is ensured by eight strain gauges. Another complex application example can be found in the measurement of intraocular pressure. Here, small forces have to be measured with low temperature drift, which was achieved by decoupling the sensor body of the "contact glass dynamometer".
