The Schneider Electric 5123182000 STP500-400 is engineered as a precision measurement instrument for hydronic control systems. This passive thermistor element delivers accurate temperature sensing while enabling maintenance without system drainage.
Featuring a stainless steel stem that inserts into water streams through separate closed pockets, this element allows replacement during maintenance without draining circuits. The sealed transition protects against moisture, while the factory-fitted gland prevents condensation and environmental contaminants.
As a passive device, it requires no power supply, firmware updates, or battery replacements—operating exclusively through the controller's measuring circuit excitation. Each unit undergoes traceable temperature calibration and includes documentation suitable for commissioning records and energy audits.
The 400mm stem length addresses specific application requirements: legacy pockets originally designed for oversized instruments, and large vessels with thick insulation cladding that shorter probes cannot penetrate effectively.

| Mounting | Immersion through separate closed pocket (pocket ordered separately) |
| Stem Material | Stainless steel, corrosion resistant |
| Cable | 2 m PVC-sheathed flying lead with 20 mm (0.79 in.) fitting and gland |
| Housing | Sealed plant-room construction, IP-rated against condensation |
| Response | Curve matched to host controller input |
| Approvals | CE, RoHS, REACH; Schneider Green Premium documentation |
The 400mm version excels in bulk storage tanks and deep-section mains where insulation thickness often exceeds standard probe lengths. This ensures accurate temperature measurement by penetrating through insulation envelopes to reach the actual fluid stream.
By resolving true fluid temperature despite thick insulation, this element maintains control loop integrity and system efficiency in demanding industrial applications.
