ME520 - Converter of signals and conditioner of analog sensors for strain gauges, DIN rail format.

APPLICATIONS

  • Conditioning of any kind of analog signal coming from a sensor to fit with data acquisition systems or Programmable Logic Controller (PLC)
  • Electrical and physical measurement: strength, torque, pressure, displacement, acceleration, strain gauges…, on test bench or control of industrial process.

DESCRIPTION

The single channel measurement model ME520 provides very complete analog outputs for measurement, conditioning and conversion of signals such as strength, torque, pressure, displacement, acceleration sensors or strain gauges.
Three parameters can be adjusted with an easy procedure that allows output trimming depending on the sensor:
  • A potentiometer to trim gain
  • A potentiometer to trim zero
  • A push button to trim calibration
A wide range of options is available: isolated power supply and many other sensors adapted to ME520 or ME52C.
