Product Description

Principle of operation:

The TH-2020 γ-ray density gauge is a nuclear gauge that receives a narrow beam of radiation, through the process material, from the source holder. The amount of radiation that the detector senses is

in proportion to the amount of the materials mass. Since the radiation source and detector are always the same distance apart and the volume of process liquid is constant, the only possible change in mass is the density of the process. The lighter the density of material, the more radiation passes through to the detector. The heavier the density of material; the less radiation passes through to the detector.

Calibration of the TH-2020 associates the detector readings, known as counts, with the density of the material in engineering units. The output range of the TH-2020 is a 4-20mA current loop signal.
Typical applications:

The TH-2020 γ-ray density gauges accurately indicate:

Density of liquids or slurries through a pipe or vessel wall without contact to the material

Percent of solids in a carrier

Interface between liquids flowing in a pipe, when the liquids differ in density
