5123170010 Schneider STP500-50 Pipe Temperature Sensor 50mm NTC 10k Thermistor Continuum Compatible 2m Cable
The Schneider Electric STP500-50 is a rugged stainless-steel immersion temperature probe designed for monitoring thermal conditions in pipes, tanks, and hydronic distribution loops. This slender probe inserts through welded pockets or directly into the medium, converting heat into resistance values for controller interpretation in applications such as chiller staging, boiler sequencing, and domestic hot-water regulation.
