Application

This force measuring chain was developed for applications where high precision is required at a very economical price. The sensor‘s strain gauge technology allows both static (constant) and dynamically changing forces to be measured. The compact design allows the sensor to be integrated into designs where room is very tight. These properties, together with the sensor’s dust protection, make the measuring chain suitable for a wide spectrum of applications, such as

• Industrial manufacture
• Manufacture of customized machinery
• Geological investigations
• Motor vehicle engineering
• Commercial agriculture
• Bridge building

Description

The body of the sensor is a flat, cylindrical disk, into which a domed force application knob is integrated. It is important that the force is applied axially to the center of the sensor. The domed form, however, minimizes the effect of a force that is not exactly axial.

A full-bridge strain gauge is used as the measuring element inside the sensor, by means of which the force to be measured is converted into a proportional electrical voltage.

The in-line amplifier increases this voltage from 0 up to 10 V. The surface against which the sensor rests is important for the quality of the measurement. It should be ground. It must be sufficiently hard and thick and not deform under load.
