WARNING!
Laser radiation. This product contains a Class 3R laser.
Avoid direct eye exposure to the emitted laser radiation
at all times during installation, maintenance, and normal
operation.
Use of controls or adjustments or performance of procedures
other than those specified in this manual can result in hazardous
radiation exposure.
CAUTION!
Position the unit to avoid excessive heat, vibration, humidity,
and dust.
CAUTION!
Failure to service or maintain the product, fitting non-approved
parts, or carrying out non-approved alterations or servicing can
be dangerous and could affect the safety of the product. It may
also invalidate the terms and conditions of the product warranty
1.4 Intended Use
The 4750-PM is a continuous particulate monitoring instrument suitable
for measuring dust concentrations and monitoring filter performance in
medium to large stacks for industrial and combustion processes. The sensor
illuminates particles in the stack with laser light to detect and measure the
amount of back-scattered light. The measurement of back-scattered light is
amplified and processed by the onboard electronics.
The instrument can measure very low to high dust concentrations, making
it suitable for monitoring filter performance in chemical, metal, and
mineral plants, and for continuous emission monitoring in power plants
and combustion processes, including refinery boilers and metal-smelting
applications.
1.4.1 Limits of Use
To achieve optimum performance and safe operation the equipment must
be operated within the limits detailed in the TECHNICAL DATA section of
this manual. Operation outside these limits may result in damage to the
equipment or failure to achieve the performance specification.
Pollution Degree 2
This equipment is designed for operation in Pollution Degree 2 environments
(where only non-conductive pollution occurs, except that occasionally a
temporary conductivity caused by condensation is expected).
