Siemens Building Technology 544-577-RK Repair Kit
Maintain precise temperature control in your hydronic and process systems with the Siemens 544-577-RK Immersion Temperature Sensor Repair Kit. Engineered for professional-grade reliability, this kit is specifically designed for rehabilitating Siemens 544-577 series sensors found in demanding HVAC and building automation applications. As a veteran-grade platinum 1K ohm RTD (375 alpha) solution, it provides high-stability resistance signaling that varies proportionally to fluid temperatures, ensuring accurate data for your controller’s PID loops.
This Siemens replacement part includes a high-accuracy 1000 Ohm sensing element and specialized components—including various support tubes for 2.5-inch, 4-inch, or 6-inch immersion wells. By replacing the internal sensing component rather than the entire well assembly, contractors can minimize downtime and avoid the labor-intensive process of draining lines. The 375 alpha curve is critical for maintaining the calibration of existing Siemens building technology infrastructure. Ensure you utilize thermal compound during installation for optimal heat transfer and response time. This kit is the standard choice for technicians focusing on HVAC sensor troubleshooting and long-term system performance.
Key Benefits- Precise Signal Accuracy: Features a high-quality 1K Ohm Platinum RTD with a .00375 temperature coefficient for stable, drift-free sensing.
- Versatile Compatibility: Includes support tubes to accommodate multiple insertion depths, specifically 2.5, 4, and 6-inch immersion wells.
- Streamlined Field Repair: Designed for rapid restoration of 544-577 series sensors without the need to breach the hydronic piping or replace the well.
- Industrial Durability: Built to withstand the temperature fluctuations common in chilled water and hot water heating loops.
- Which sensors can be repaired with this kit? It is designed to service any Siemens immersion temperature sensor with the 544-577 prefix.
- Does this include the thermowell? No, this is a repair kit for the internal sensing element and hardware; the stainless steel well must be already installed.
- What tools are required for installation? Technicians should have a flat-blade screwdriver, 1-1/4 inch wrench, and thermal grease (such as Dow Corning #340) for a proper fit.
