6 Using the probes
6.1 Air-borne sound probe L60
Death or serious injury possible.
Incorrect operation, damage to the
device as well as damage to accessories can impair the explosion
protection.
(1) When using the ultrasonic probe L60 in Ex zone 0, it is
imperative that it is connected via the probe extension cable and the
housing is connected to the local potential equalization. Only the
grounding kit supplied by SONOTEC
®
should be used for this purpose.
(2) Prevent friction and impact sparks that could occur, for
example, when the probe is dropped.
For connecting the grounding kit: see ‚7.3 Using the grounding kit‘!
The L60 probe for air-borne ultrasound serves for general detection of
leakages in excess pressure and in vacuum range. The slot for probes is
provided with a notch which indicates the correct position for insertion.
Install the required probe in the specified position. You must feel the
connector click into place.
