These level transducer probes for super-market refrigeration systems provide continuous measurement of refrigerant levels. The probes warn of excessively high or low refrigerant levels, indicate trends in refrigerant usage, and aid troubleshooting. They are designed to be inserted directly into vertical and horizontal high-pressure refrigerant receivers, or to monitor refrigerant in suction accumulators. Suitable for R-22, -134a, -404A, -507, refrigerant oils, secondary coolants, and other approved fluids, they provide a computer-compatible, 0- to 5- or 1- to 6-vdc output signal.
