BRTD Tip Sensitive Copper Tip Bearing RTD with Electrically Isolated Tip is a resistance temperature detector specifically designed for bearing temperature or other rotating shaft temperatures. The copper tip probe is inserted directly into drilled holes (such as bearing housing, machine components) or the process. The copper tip design allows small changes in temperature to be detected quickly, helping to avoid major damage to the bearing or shaft. TempoTech bearing RTD comes with an electrically isolated tip, making it suitable for use in high-voltage motors and electrically heated bearings. The electrically isolated tip helps to prevent any signal interference caused by electric currents.

Application Note
BRTD Tip Sensitive Copper Tip Bearing RTD with Electrically Isolated Tip is essential for bearing temperature monitoring in various critical equipment, including rotors, generators, turbines, and transformers, to ensure efficient power generation and prevent overheating. They are also widely used in other rotating machinery such as pumps, dynamos, compressors, and drilling equipment, helping detect temperature variations that may signal potential failures. Additionally, these temperature sensors are employed in diverse applications like aircraft engines and auxiliary power units, diesel engines, turbochargers, gearboxes, conveyor systems, and locomotive bearings, providing real-time monitoring to enhance performance, prevent damage, and ensure reliable operation across these high-stakes systems.
