DESCRIPTION
Non-contact capacitive Air Gap Transmitter (AGT) for the measurement of the distance between its
underlying surface and a metallic target. Each transmitter consists of a Sensor (AGS), an Air Gap
Adapter (AGA) and a Conditioner (AGC).
Conditioner
The conditioner provides three signal outputs :
1
 MinGap voltage (V)
 Pole Profile voltage (V)
1
 Pole Profile or MinGap current (mA)
All outputs are galvanically isolated and the current output is factory set on Pole Profile. The digital
technology combined with active temperature compensation allow linearization adjusted with great
accuracy and resolution, with stable and repetitive behaviours. Industrial metal housing enables installation in harsh environments.
Sensor and Adapter
Designed for long life cycles, harsh environments and strong magnetic fields. The sensor shape is
suitable for its installation on the stator wall of generators and motors. The sensor is connected to
the air gap adapter via a flexible cable and a connector allowing routing through ventilation holes.
This cable is protected on its entire length by flexible polyamide tubes. The air gap adapter is connected to the conditioner via a flexible cable and a 4 poles connector. This cable is protected on its
entire length by a flexible metal conduit.
