At HB Products, we've been harnessing the capacitive measurement principle: A robust technology developed in the 1940s, to engineer cutting-edge switches and level sensors for refrigeration systems ❄️
This principle forms the backbone of our sensor technology, which has evolved over 25+ years, initially focusing on Ammonia and now compatible with all refrigerants.
So, how does it work?
Imagine a capacitor formed within a vessel - the center rod is one electrode, and the vessel or reference tube is the other. When liquid displaces air or gas around the electrode, the change in dielectric constant alters the capacitance.
Our sensors expertly convert this capacitance into precise, reliable data – either as an analog 4-20 mA output or a digital ON/OFF signal. And yes, each piece of our technology is meticulously factory-calibrated for specific fluids.
