100mm 1.8k Nickel 3-Wire Immersion Probe with 2m Cable

The Schneider Electric STP100-100 Pipe Temperature Sensor is a rugged stainless-steel immersion probe designed for monitoring thermal conditions in water pipes, tanks, and hydronic distribution systems. Part of the reliable STP family, this sensor features a slender probe that inserts directly into the medium or through welded pockets to provide accurate temperature readings.

The temperature-sensitive nickel element converts heat into resistance values that controllers interpret for applications including chiller staging, boiler sequencing, and domestic hot-water regulation. With a potted, moisture-resistant body and sturdy cable gland, the sensor maintains reliable operation even in condensation-prone plant rooms and during wash-down procedures.

As a purely passive device requiring no auxiliary power supply, installation is simplified in congested mechanical spaces while eliminating common retrofit failure points. Each unit undergoes factory calibration against traceable references, supporting BMS commissioning reports and energy audit documentation requirements.

The 100 mm probe length is ideal for medium pipework applications, particularly suited for main distribution headers and primary plant manifolds where the stem must reach the centerline of larger bore pipes. This model is commonly selected for chiller and boiler return-line monitoring in commercial building systems.
