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 :

. MinGap1 voltage (V)

• Pole Profile voltage (V)

• Pole Profile or MinGap1 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 in-

stallation 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 con-

nected 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.
