Stator Slot Resistance Temperature Detector (RTD): A Game-Changer for Industrial Applications

Stator Slot Resistance Temperature Detector (RTD): A Game-Changer for Industrial Applications

Kamet delivers industrial-quality RTD sensors specifically designed for use in the slots between the stator windings of motors and generators. Our Stator Slot RTD sensor has sensors along most of its length, providing continuous average temperature readings across a wide area. This design allows for very accurate average temperature monitoring and ensures no localized hot-spots are missed.

Benefits of Stator Slot RTD Sensors

Kamet's Stator Slot RTD's are already key components in the hydroelectric industry, wind turbines, and other generators. However, accurate and consistent measurement of thermal shifts in stator windings is highly relevant throughout all industries where electric motors are in use. As such, Kamet strives to bring these listed benefits of Stator Slot RTD sensors to the attention of a broad range of industries, facilitating companies in keeping up with current electric motor and generator development trends.

Stator slot temperature readings can be used to:

  • Prevent overheating, increasing longevity
  • Ensure precise and timely cooling, improving motor efficiency
  • Provide early indication of core component failure or incorrect voltage (e.g., temperatures continue to increase despite cooling)
  • Protective functionality:
  • Significant cost savings in the long term (prevents unnecessary damage to insulation or mechanical elements)
  • A considerable contribution to safety (e.g., during peak demand at a hydropower plant)
  • Reliability, as the motor has less "downtime"

Stator Slot Sensors Design and Properties

Our sensors are designed with the following properties:

  • Both flat and thin to fit between windings
  • Usually made with wire-wound RTDs
  • Sensors along the entire length
  • Durable: resistant to shock, pressure, and vibration
  • Bifiliar design to prevent measurement errors caused by induction voltage
  • Withstand voltage of up to 3KV
  • Maximum short-circuit current of 20mA
  • High-temperature epoxy glass casing provides insulation class F or H (F=155°C, H=180°C)
  • Specialized sheath materials (e.g., teflon) can increase operating temperature up to 250°C
  • Single or dual elements
  • Available in versions suited for hazardous environments (Atex and IECEx certification)
