RDP Electrosense

  • In-line Amplifier
  • Compatible with any standard RDP LVDT (without integral electronics) and most LVDTs from any manufacturer
  • Produces a DC output voltage or current
  • Screw terminal connections
  • Simple controls for gain and zero adjustment
  • Input zero switch
  • Signal overload indicator

Details

The S7AC is a signal-conditioning unit for use with transducers requiring AC excitation and synchronous demodulation, producing a DC output voltage or current. Units may be master-slaved in systems where carrier frequency beating is a problem.

The unit is housed in a robust aluminium case with connections via glands, all sealed to IP65 specification. All controls are internal with coarse range switches and fine adjustment potentiometers for gain and zero setting. Other controls include a zero-input switch, over-range indicator and pins to which resisters can be fitted for half-bridge operation.

The unit is suitable for use with the complete range of RDP LVDT transducers.
