Measuring eye with thin-film sensor and integrated amplifier

The press-in sensor has been developed for applications where deformations caused by external forces are to be measured in existing components. Due to the press-fit method, installation is simple and an existing component is given the properties of a force transducer.

The press-in sensor can be used in existing structures from a material thickness of 4 mm and a tensile strength of > 350 N/mm2. It issuitable for use in structures with a strain of 0,1‰ £ e £ 0,25‰. The press-in sensor contains an integrated programmable digital amplifier. After fitting the sensor, zero point and sensitivity are set using the tecsis handheld programming unit (EPE01). This makes a standardised mA or V signal available. Depending on the installation, an overall accuracy of < 2% F.S. scale range is achieved.

This press-in sensor uses an implanted thinfilm.
Thin film sensors, manufactured using advanced technologies, have all advantages of conventional film strain gauges, but without their considerable disadvantages (temperature response of the adhesive and creep). The force transducer meets EN 61326 for electromagnetic compatibility (EMC).
