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

Adjustable strain gauge measuring amplifier with analogue output

Our configurable measuring amplifiers are ideal for universal signal processing of strain gauge strain, weight and force sensors. Their advantage is that the zero point, tare and gain can be re-taught on site after the sensor has been installed (teach function). This allows you to utilise the maximum possible output signal in your application.

The measuring amplifiers are available in two versions:

Pure circuit board type MV8.0 – This variant can be installed directly in our sensors and provides a compact and efficient solution.

External housing type MV8.1 – This version can be connected to a variety of sensors and offers flexible application options.

  • For static and cyclical applications

Strain gauge measuring amplifier MV 1.0 / 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.
