MC2A / MC3 - Measuring amplifiers for inductive and strain gauge technology-based transducers

The measuring converter type MC2A completes inductive HBM transducers to a simple measuring arrangement. It has two main purposes:

  • The measuring converter provides a supply voltage for the inductive half bridge
  • The signal from the connected transducer is converted into a proportional DC signal.

A pair of precision resistors connected to the Wheatstone bridge completes the inductive half bridge arrangement. The generator provides a symmetrical bridge excitation voltage of 1.8V (effective value) with a carrier frequency of 5 kHz.

The measuring converter type MC3 is used with strain gages in a full bridge circuit or with strain gage transducers to construct an uncomplicated and economical measuring system.

Suitable indicating equipments for connection to this system include digital indicators for switchboard installation. The MC3 supplies the bridge supply voltage of the transducer, amplifies the transducer output signal and outputs a DC voltage signal of -5V... 0 ... +5V proportional to the measured value.

A limit switch with open collector output can be adjusted over the range of 0 ... +5V.

When equipped with an optional final stage, an output current of 4mA ... 20 mA is available.
