TAG level switches are designed to detect the presence of materials that accrue in the surroundings of the electrode’s position. Materials can be fluids, powders, granules and conductive or non-conductive, grains, powders, plastics, oils or water. The electrode may be installed in free air or closed vessels, including metallic or non-metallic pipes or reservoirs.
Some of the principals on which the TAG units function are changes of RF current and voltage, loss of energy and changes of dielectric constant versus air.
RF is transferred from the feeler through the mass of the material to the ground point of the sensing unit. This causes RF energy losses. The variations of RF current are converted to a DC signal that is sent to the control box to activate the dry contact relay. The set will continue to function even when the feeler is completely covered by material.
The function of the sensing unit is not hampered by material sticking to it or influenced by the relative humidity of the environment. After initial fitment of TAG, no further adjustment is required of these fit-and-forget devices.
