Multi-channel measuring amplifier (FL 152)

16 input channels for processing of analogue strain gauge measuring signals, easy connection by multi-pin input port



  • Stresses and strains occurring in components are determined in experimental stress and strain analysis by measuring strain.
  • In industry, strain is often recorded by strain gauges.
  • Since strain gauges deliver only small analogue measuring signals, the signals must be amplified in measuring amplifiers.
  • Then they are converted into digital pulses and displayed as measured strain.
  • These strains may also be evaluated and processed on computer.
  • FL 152is a multi-channel measuring amplifier which supplies the strain gauge bridge circuits with power and processes the received measuring signals.
  • The measuring amplifier includes 16 input channels.
  • The strain gauge measuring points are connected to associated balance potentiometers by a 68-pin multiport.
  • The multi-channel measuring amplifier is operated via touchscreen or via PC using the supplied software.
  • The measured values can be read on the touchscreen and in the software and can be saved and processed on a computer (using an application such as MS Excel).
