Description
The Thrust Bearing PT100 RTD Sensor is an ultra-compact temperature sensor developed for accurate monitoring of thrust bearings, shafts, and other space-constrained industrial components. Featuring a PT100 Class A sensing element, 3-wire configuration, and a 3 mm diameter × 20 mm probe, it delivers precise temperature measurement while fitting into locations where standard bearing sensors are too large. Its miniature, low-mass construction enables rapid heat transfer to the sensing element, allowing faster detection of abnormal temperature rises that can indicate bearing wear or lubrication issues.
Manufactured with an SS316 stainless steel sheath and a durable Teflon/Teflon/SS armored cable, the sensor operates reliably over a temperature range of -50°C to +400°C. The compact design ensures secure installation without interfering with moving components, making it particularly suitable for critical rotating equipment where installation space is limited. The 3-wire PT100 configuration minimizes lead resistance errors and provides stable, high-accuracy measurements for industrial monitoring systems.

FAQs
1. What is a Thrust Bearing PT100 RTD Sensor?
A Thrust Bearing PT100 RTD Sensor is a compact Resistance Temperature Detector (RTD) designed to accurately monitor the temperature of thrust bearings, shafts, and other confined rotating components. It provides reliable temperature measurement for equipment protection and condition monitoring.
2. Why is a Miniature RTD Sensor used for Thrust Bearings?
Thrust bearing locations often have very limited installation space. A compact PT100 RTD Sensor provides accurate temperature measurement without interfering with surrounding mechanical components, making it ideal for confined bearing applications.
3. What is the difference between a Thrust Bearing RTD and a Standard Bearing RTD?
A Thrust Bearing RTD is designed with a much smaller probe for installation in confined thrust bearing locations, whereas a Standard Bearing RTD is intended for larger bearing housings with more available installation space. Both provide accurate bearing temperature monitoring but are optimized for different mounting requirements.
4. Do you also manufacture RTDs for larger Motors and Turbine Bearings?
Yes. Aavad manufactures a wide range of temperature sensors, including Bearing Temperature Detector (BTD) PT100 RTD Sensors, Turbine Bearing Temperature Sensors, and other industrial RTDs for motors, turbines, generators, pumps, compressors, and predictive maintenance applications.
