Analogue signal processing

Analogue signal processing

When used for industrial monitoring applications, sensors can record ambience conditions. Sensor signals are used within the process to continually track changes to the area being monitored. Both digital and analogue signals can occur.
Normally an electrical voltage or current value is produced which corresponds proportionally to the physical variables that are being monitored

Analogue signal processing is required when automation processes have to constantly maintain or reach defined conditions. This is particularly significant for process automation applications. Standardised electrical signals are typically used for process engineering. Analogue standardised currents / voltage 0(4)...20 mA/ 0...10 V have established themselves as
physical measurement and control variables.

Weidmüller meets the ever increasing challenges of automation and offers a product portfolio tailored to the requirements of handling sensor signals in analogue signal processing

The analogue signal processing products can be used universally in combination with other Weidmüller products and in combination among each other. Their electrical and mechanical design is such that they require only minimal wiring efforts.

Housing types and wire-connection methods matched to the respective application facilitate the universal use in process and industrial automation applications.

The product line includes the following functions:

  • Isolating transformers,  supply isolators and signal converters for DC standard signals
  • Temperature measuring transducers for resistance thermometers and thermocouples,
  • frequency converters,
  • potentiometer-measuring-transducers,
  • bridge measuring transducers (strain gauges)
  • trip amplifiers and modules for monitoring electrical and non-electrical process variables
  • AD/DA converters
  • displays
  • calibration devices

The products mentioned are available as pure signal converters / isolation transducers, 2-way/3-way isolators, supply isolators,  passive isolators or as trip amplifiers.
