Temperature Sensors for Bearings & Winding

PT100 SENSORS FOR INDUSTRIAL MOTOR MONITORING

Temperature monitoring is vital to the long-term performance and safety of electric motors. PT100 thermal resistors provide accurate and stable measurement of heat buildup within motor bearings and windings — helping prevent premature wear, mechanical stress, or insulation failure.

At Valiadis S.A., we supply high-quality platinum resistance temperature detectors (RTDs) for integration into both new and existing motors. Built to IEC standards and tested for linearity, precision, and durability, our sensors are designed to perform reliably in harsh industrial environments.

Applications

• Motor bearings
• Winding temperature monitoring
• Machinery and textile equipment
• Railway motor systems
• Heavy-duty industrial settings

Sensor Types

• WZPM-201: Threaded bearing sensor (−50°C to 180°C)

• WZPD series: Embedded winding sensors for medium and large motors
  Both versions are available in single or double element formats, with customizable lead lengths and optional shielding.

Key Features

• High-accuracy platinum thermal resistance

• Fast response time and minimal deviation

• Resistant to vibration, humidity, and mechanical stress

• Solid construction with sealed connections

• Insulation-resistant up to ≥200 MΩ

• Lead-out wires with high-temperature fluoropolymer insulation

Whether for monitoring, logging, or integrating with control systems, our PT100 sensors offer precise temperature readings under real-world operating conditions. Custom configurations are available on request.
