Xylem-McDonnell & Miller 157S-RBP-MD Low Water Cut-Off & Pump Controller W/Conductance Probes 176503

The Xylem-McDonnell & Miller 157S-RBP-MD Conductance Prbs, S.W.#176503, is a conductivity probe used in hydronic heating systems, specifically boilers and chillers. It gauges the electrical conductivity of the water passing through it, providing important details regarding the functionality and state of the system.  The probe most likely operates by sensing the electrical resistance of the water, however, the details are still unknown. Temperature, pollutants, and dissolved minerals are some of the variables that affect this number. It is likely that hydronic heating and cooling systems, especially boilers and chillers, use the Xylem-McDonnell & Miller. The word conductance implies that it is a measurement of a fluid's capacity to conduct electricity, which can be a sign of several different things, including temperature, mineral content, and water quality.
