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 extension
cable 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 extension cable
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 consists of an integral flexible triaxial cable of 2 meters terminated by an adapter and a four pins connector. A three
core shielded extension cable allows the signal transmission to the AGC conditioning unit over a
length up to 12, 16, 19, 22 or 28 meters.
