5123172000 Schneider STP500-100 Pipe Temperature Sensor 100mm NTC 10k Thermistor Continuum Compatible 2m Cable

The Schneider Electric STP500-100 Pipe Temperature Sensor is a rugged stainless-steel immersion probe designed for monitoring thermal conditions in water pipes, tanks, and hydronic distribution systems. The slender probe inserts through welded pockets or directly into the medium, converting heat into resistance values for controller interpretation in chiller staging, boiler sequencing, and domestic hot-water regulation.

Featuring a potted, moisture-resistant body and sturdy cable gland, this sensor maintains dry electrical connections even in condensation-prone plant rooms. As a purely passive device requiring no auxiliary power, it simplifies wiring in congested mechanical spaces and eliminates common retrofit failure points. Each unit is factory-checked against traceable references, supporting BMS commissioning and energy audit documentation.

The 100 mm STP500 sensor is ideal for mainstream distribution pipework, pairing a responsive 10 kOhm thermistor with a stem length suitable for central headers. It is particularly valuable when upgrading Continuum sites with new plant equipment while maintaining existing controller input curves.
