Measuring amplifier

Measuring amplifier

Signal conditioning is an important component of our measurement system. We use either measuring amplifiers integrated in the sensors or located externally in their own housing for this purpose. Measurement amplifiers are used to transform sensitive strain gauge bridge signals into standardised analog or digital output levels. Wireless radio transmission of measurement data is also possible.


Integrated strain gauge measuring amplifiers

Signal conditioning is realised via a measurement amplifier board integrated in the sensor. The measuring amplifier is encased in the sensor, providing it with permanent protection. The following output variants are available: analog current and voltage signals, switching outputs or an RS485 interface. Optionally, customers can adjust the zero point and gain via an I²C interface.

  • Encased design (IP67 protection)
  • Optionally available with test output

Strain gauge measuring amplifier MV 1.0 / current output

Measuring amplifier with current output

As an alternative to encapsulation with the sensor, the board in the case of this measurement amplifier is installed in an external housing. The standardised current output signal is 4 – 20mA. Other signal levels are also possible on request. The zero point and gain can be adjusted via potentiometers accessible to customers.

  • 1 channel version
  • Die cast aluminium case
  • Encased design (IP67 protection)
  • Optionally available with test output

Strain gauge measuring amplifier MV 2.0 / voltage output

Measuring amplifier with voltage output

The board in the case of this measuring amplifier is installed in an external housing. The standardised voltage output signal is 0 – 10V. Other signal levels are also possible on request. The zero point and gain can be adjusted via potentiometers accessible to customers.

  • Die cast aluminium case
  • Encased design (IP67 protection)

Radio wireless transmission system with analog output

Radio wireless transmission system

This system offers the option for wireless transmission of measurement data from strain gauge sensors. The modules involved are a radio transmitter connected by cable to the sensor and a radio receiver. The standardised current output signal of the receiver is 4 – 20mA. Other signal levels are also possible on request.

Radio wireless transmission system with USB output

Radio wireless transmission system

This system offers the option for wireless transmission of measurement data from strain gauge sensors. It consists of a radio transmitter connected by cable to the sensor and a USB radio receiver. The receiver is directly connected to a PC. Evaluation of measurement data is realised with software specially developed by us. They enable the graphic depiction of measurement data and archiving of data in Excel.
