FL 152 Multi-channel measuring amplifier

FEATURES:

 

  • 16 input channels for processing of analogue strain gauge measuring signals, easy connection by multi-pin input port
  • integrated software for evaluation of stress and strain analysis experiments (FL 120, FL 130, FL 140) and experiments relating to forces in trusses (SE 130, SE 110.21, SE 110.22)

DESCRIPTION

Technical Specification

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 152 is 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).
