Parker Hannifin: liquid level probes

Transducer-type liquid level probes for halocarbon refrigerants are designed for use on supermarket racks. They support monitoring, performance and charge management, and troubleshooting via a central microprocessor-based control panel, the manufacturer says. The capacitance-based probes interpret liquid level in a receiver, accumulator, or similar pressure vessel as a selectable dc voltage range of either 0 to 5 or 1 to 6 V when powered by an 11- to 47- vdc regulated remote source.
