10.- SIGNAL CONDITIONERS.

Control board. Horizontal position in instruments serie LDP-124

Vertical position in instruments serie LDP-144

The control board contains the Analog/Digital con- verter, the Signal Conditioner and other compo- nents.

The function of the Signal Conditioner is amplifier and make the linearisation of the signal received from the sensor and there is one Signal Conditioner for every model of RTD or Thermocouple sensor. The trimmers for Span and Zero are also located on the Signal Conditioner. Use these trimmers only for calibration procedure.
