Description of Equipment:
General - The LB 480 Series Scintillation Measurement Equipment is used as part of a measuring system for
monitoring industrial processes. The equipment is used for continuously measuring the level or weight per unit
area, in tanks or bins, of liquid, granular, viscous or encrustation-forming media and for measuring conveyor belt
charges as well as the density of liquids, suspensions, slurries and bulk solids. The measurement principle is
based on the absorption of gamma rays. The radiation source is not part of the measuring equipment and is not
included in the product Approval.
Construction - The LB 480 Series Scintillation Measurement Equipment consists of a scintillation detector with
associated electronics in an explosionproof/dust-ignitionproof enclosure with separate sensor and wiring
compartments. The sensor and wiring compartments are separated by NRTL listed cemented feedthroughs.
The sensor and housing (socket) are constructed of 304 or 316 stainless steel. The wiring compartment
contains four ½-inch NPT entries and contains a threaded cover. The socket attaches to the sensor by
cylindrical joint fastened with six bolts. The bolt holes terminate under the threaded cover inside the wiring
compartment) and therefore contain six threaded plugs to form a valid flamepath. The equipment is available
with an optional window which is cemented into the sensor.
Ratings - The equipment is rated for use in an ambient temperature of -40°C to +65°C (or +80°C). The
equipment operates at 100-240 Vac (12 VA) or 24 Vdc (12 W).
