Understanding Stator RTDs and Their Functioning

Why Platinum and Other Materials Matter in RTD Design

Stator RTDs are a type of temperature sensor that measure temperatures based on the temperature coefficient of their material. Typically made of platinum, these sensors offer a linear relationship between resistance and temperature, resulting in high accuracy in temperature readings. Copper and Nickel are other optional element materials. The lead wire style is PTFE.

The Science Behind RTD Accuracy: Temperature and Resistance

The principle behind RTDs is that as the temperature increases, so does the resistance of the RTD element, allowing for precise temperature measurement.

Unmatched Advantages of Temp-Pro’s Stator RTDs Custom Configurations for Every Application

Certified Quality and Proven Reliability 

Stator Slot RTDs are specially designed sensors intended for use within the slots between the stator windings of motors and generators. They are a popular solution among OEMs. We prioritize product quality, manufacturing all components to meet or exceed OEM specifications and tolerances.

Temp-Pro RTDs are available in multiple configurations, such as Single Element stator winding RTDs, Dual Element stator winding RTDs and Dual Independent Element stator winding RTDs. Other options for our RTDs include rear exit, side exit, custom holes and sizes.

Installation and Maintenance of Stator RTDs

Placing RTDs for Maximum Temperature Monitoring Accuracy

By placing sensors along the length of the stator slot, these RTDs deliver continuous average temperature readings over a wide area. This unique design allows for precise and accurateTemp-Pro Stator RTD Illustration monitoring, ensuring that no To achieve optimal performance, it is recommended to position our Stator Slot RTDs securely near the hottest point in the stator windings. Ideally, two sensors per phase of the motor should be used for comprehensive temperature monitoring. localized hot-spots go unnoticed.

Semi-Conductive Materials: Enhancing Protection and Performance

These sensors can be embedded in NEMA G-11, made out of a Semi-Conductive Material or feature a Semi-Conductive coating applied to the outside of the G11 laminate enclosure, ensuring reliable and accurate temperature readings. The Semi-Conductive material provides the same mechanical protection with the added benefit of corona dissipation.

Prevent Overheating and Extend Equipment Lifespan

While generator core failures are rare, their potential impact is catastrophic. In most cases, generator cores are monitored online using our embedded RTDs placed between top and bottom stator bars at specific locations in particular core slots. This ensures continuous assessment of equipment condition and enables early detection of hot spots.

Proactive Maintenance: Early Detection of Hot Spots

Paddle Stator RTDs, also called Air or Gas RTDs, measure incoming or outgoing air temperatures in motors and generators.
