®
The SHLG
source holders are used to position and protect a radioactive source
near a process vessel or pipe. Radiation from the source is directed through the
process by an integral collimator. A radiation detector placed opposite the source
holder measures radiation fluctuations caused by process condition changes. The
detector correlates radiation levels to process conditions.
The radiation beam for the SHLG
push/pull shutter. In the ON position, the source tube assembly is pushed down
against the gasket stop with the handle. The source is in the OFF or shielded
position when the source tube assembly is in the extended position.
These source holders are one component of a continuous or point level, density,
or weight measuring system. The SHLG
devices secured in a fixed position near a vessel or pipe and are responsible for
directing radiation through the process material.

The SHLG
source holders are constructed from stainless steel or carbon steel
with polyester powder coating and perform the following:
•
Houses a radiation-emitting source capsule.
•
Protects the radioactive source.
•
Provides a means for shielding and locking out the radiation beam.
•
Directs radiation safely through the process.
•
Shields all areas in which radiation is not intended.
