Strain Transducer X-109-7

especially suitable for static applications

For accurate weight measurements

The Strain Sensors are particularly suitable for static measurements, such as those found in the monitoring of structures or in weight measurement. Thanks to the digital input, the zero point adjustment can be taught in conveniently via the control unit in a captive manner.

Strain Transducers are predestined for use in the following applications:

  • Weight measurement via strains in load-bearing elements enable flexible retrofitting of existing systems
  • Determination of mechanical loads for component analyses and component design
  • Limit value monitoring and monitoring of mechanical loads to avoid critical overloads in plants and structures

X-Sensors Strain Transducers reliably measure even small strains on the surface of flat structures. Despite the simple screw-on mounting, the measured values are comparable to glued-on strain gauges, while avoiding their disadvantages. Thanks to the integrated, extremely low-noise and highly stable signal Amplifier, the Sensors are simple and universally applicable.


  • For static applications
  • With external reset or tare control input for zero point adjustment, zero point correction is stored captive
  • Suitable for level, weight and structure monitoring
  • Reliable measurement of smallest strains on rigid structures
  • Integrated measuring amplifier, optionally with ± 10 V or 4-20 mA as robust output signal

Measurement principle

How it works

The Strain Sensor X-109-7 detects the strain between the two screw-on surfaces and amplifies it mechanically. This concentrates the strain on the measuring point, where it can be easily detected with a resistive measuring bridge. The integrated bridge Amplifier takes care of signal conditioning and provides a uniform, robust output signal. The solid steel housing and the tight design (IP54) guarantee problem-free operation, even under difficult environmental conditions.

Zero point tare

The zero point adjustment on these Strain Sensors is done by a digital zero point adjustment mechanism. The zero point setting is permanently stored, i.e. the zero point correction is available again even after switching off. Thus, a permanently available installation tare is available. Therefore, these Strain Sensors are suitable for all static applications. The number of taring operations is limited to 100,000.

Zero adjustment is triggered via an external reset or tare control input. The mechanism is available with “Active Low” and “Active High” logic.
