3 Product Description
3.1 Principle of Operation
The SHLD 2 is used to position and protect a radioactive source near a process
vessel, pipe or on a conveyor belt/spiral conveyor. 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
such as level and density.
The source container shields the environment against gamma radiation and protects
the radioactive source against mechanical damage or chemical influences. In case of
large measuring ranges, such as high vessels, two or more source holders are used.
3.2 Components
The SHLD 2 houses a source capsule that provides gamma energy for radiation-
based mass-flow, point level, level, and density measurements. This compact,
lightweight source holder is available in low carbon steel with polyester powder
coating or an optional 316 stainless steel option. Additionally, the SHLD 2 has
lead shielding material and a rotary shutter.
