H.B. Products are dedicated to provide optimal solution for level measurement and control of oil and refrigerant. Thus providing best possible operational safety to expensive refrigeration equipment like compressors, oil separators, condensers, high and low pressure receivers and evaporators etc. H.B. Products have 20 years of experience in development of electronic sensors for Ammonia and all other types of refrigerants including CO-2.

A capacitor is formed when a level – sensing electrode is installed in a vessel. The metal rod / electrode acts as one plate of the capacitor and the reference tube acts as the other plate. As the level rises, the air or gas normally surrounding the electrode is displaced by liquid having a different / higher dielectric constant. Capacitance instruments detect this change and convert it in to a proportional out-put signal, o to 100 % level.
