Installation

The main amplifier (and RMA if applicable) is best mounted in an area that is clean, dry,

vibration free, non-hazardous, within the ambient temperature range, and non-corrosive

to the electronics or its enclosure. The door should be accessible for viewing and to

allow calibration of the main amplifier.

Note: Do not mount amplifiers in direct sunlight.

The probe should be mounted and onto a vibration free structure and using the

mounting flange. The gap between probe and target should be enough so that there is

no danger of the target damaging the probe. The probe environment must be within the

probe's ambient temperature range and non-corrosive to the probe's body. Refer to

Applications drawings on page 29.

Note: Installation and wiring must be in accordance with all governing regulations.

Where possible, use flexible conduit. The probe components should be interconnected

via flexible conduit. This allows for easier removal or adjustment of the probe and

mounting flange assembly.
