Leak detector overview

The leak detector identifies aerosol cans that are leaking propellant as they are carried

along a conveyor belt at high speed. The leak detector consists of an air extraction

arch, air filter/regulator, sample cell, sensor head and either a Venturi or 3-phase

blower.

Figure 1-3 Monitoring aerosol cans for leaks on a conveyer

A.

Air extraction arch — draws the air from around the aerosol can into the

sample handling system

B.

Air filter — for the removal of air particles and leaked contents of the

aerosol cans

C.

Sample cell — laser light is directed through the air extracted from around
the cans and back into the sensor head.

D.

Sensor head — contains the lasers and laser light detector. It is ATEX

Category 3 rated for a Zone 2 explosive environment.

E.

Conveyor belt — transporting the aerosol cans

Aerosol cans (not shown) are moving along the conveyor belt.

The control console (not shown) is located outside the explosive environment and is

not ATEX rated.
