Laser Classification
The Model LS9000 Non-contact Length and Speed
Gauge (Model LS9000) is classified as a IIIb laser device.
This category contains infrared and visible laser devices
with powers up to 500 mW. The optical gauge in the
system uses a 50 mW solid-state laser device operating
between 760 and 800 nm (near infrared region of the
spectrum).
A class IIIb product must have the following safety
features:
A 5-second delay after power-up before laser
radiation is emitted from the gauge.
An indicator light to inform personnel near the
gauge that laser radiation is being emitted.
A mechanical device to physically block the laser
beam from exiting the gauge.
An interlock circuit to shut off the laser when the
circuit is opened.
All hazards must be properly identified with warning labels.
These basic safety features are incorporated to promote safe operation of the
laser.
A class IIIb laser must also have a key switch to power the laser, ensuring that
only trained personnel can operate the instrument. Because the location of the
gauge can often make it difficult to access a key switch, the key switch needs
to be installed by the final user. It should be placed in a location that will be
readily accessible to the operators. For more information on installing the laser
key switch, see the Installing the System section of the Instruction Handbook.
The user of a laser device must comply with a different set of regulations.
Many countries and individual states have passed legislation regarding the use
of laser products.
