Radioactive Source measuring Radioactive Y-ray level gauges

Product Description
Principle of operation:
The TH-2011 γ-ray Level Gauge is a continuous level nuclear gauge.The gauge receives a shaped or collimated beam of radiation from the source holder through the process material.The material in the vessel acts as a shield that prevents a portion of the detector from exposure to the radiation field.As the process material level decreases, the detector senses more radiation.As the process material level increases, the detector senses less radiation.Calibration of the level gauge associates the detector readings, known as counts, with the level of the material in engineering units.The output range of the gauge is a 4-20mA current loop signal, in proportion to the level of the process.
Typical applications:
The level gauges accurately indicate the level of liquids or bulk materials in vessels, eactors, or tanks.
In order to achieve a level indication over the desired length, it may be necessary to use more than one detector.
The accuracy of quality control systems that use TH-2011γ-ray level gauges is profitable to a wide range of industry operations.A number of applications that use a level gauge are:
1.Pulp and Paper:
1.Liquors
2.Bleach plant chemicals
3.Coating chemical storage
4.Lime mud
5.Wastewater treatment tanks
2.Chemical:
1.Low pressure/low vapor chemical storage
2.Settlers
3.Surge tanks
3.Food and beverage:
1.Food slurries
2.Pastes
3.Syrups
4.Dough level
Intermediate batch storage
4.Water and wastewater:
1.Settling/aeration tanks
2.Clarifiers
3.Sludge holding tanks
4.Wet wells
The TH-2011 γ-ray level gauges especially used as a non-contact, level measurement transmitter for containers (mixers, reactors, hoppers, silos, tanks) e.G.With the material and liquids which has the characteristic of high temperature, pressure, viscosity, corrosion and severe toxicity.
TH-2011 can detect the interface between liquids(solids) in a vessel, when the liquids(solids) differ in height.
