Catalogue excerpts

Flat dimensions with four mounting screws Easy mounting with two screws Narrow dimensions with two mountings screws High-precision measurement of strains up to 1200 pm/m • For dynamic applications with external input for automatic zero-point adjustments • For indirect force and deformation measurements • Measuring very small strains in rigid structures • With integrated amplifier with ± 10 V or 4-20 mA Surface strain sensors monitor the strain between its two mounting screws and amplifies this mechanically. In this way the strain is concentrated in the measuring area and can therefore be measured using a resistive strain gauge bridge. The integrated low-noise amplifier raises the signal to an easily handled standard industrial output level. The solid steel body and sealed construction (IP67) guarantees trouble-free installation even under harsh environmental conditions. • Force measurement in machineries (e.g. presses, welding tongs, assembly machines) • Force measurement in presses and injection-molding machines • Monitoring of process parameters and maximum peak values

Zero reset / adjustment Reset Eingang Digital input for automatic zero-point adjustments: The reset input has an internal pull-up resistor. Hence an open reset input forces the sensor in measurement mode (Operate). To set the output to zero (Reset) the reset input must be tied to 0V. The following paramters should be respected in regard to the external zero-point adjustment: The following graph describes the characteristic during the zero point adjustment: Strain sensors for dynamic applications

The strain sensors should be mounted on machined surfaces N7 (N9 for X-103) with a flatness to within 0,1 mm (0,5 mm for X-103). Use the following parameter for tighten the socket screws: The accuracy includes the following parameters: 1. Linearity and hysteresis The linearity and hysteresis specifies the measuring error in reference to the ideal BFSL curve. The maximum measuring error is stated in reference to the full scale value. This means that an accuracy of 0.5 % FS at a strain sensor with a measuring range of 0...250 pm/m correspondents to a measuring error of only 1.25 pm/m. 2. Repeatability...
