Screw-in temperature sensor TBR22

strap-onwirelessbuilt-in transmitter

Features

• Measures temperature at bus bars, cable ends and contact points with high accuracy and reliability.
• Designed for use on systems with voltages up to 500 kV.
• Available in self-induction (battery-less) or replaceable battery (CR3032) versions for safe operation in high-voltage environments.
• Centralized monitoring software without limits on number of sensors per station or number of substations.
• Suitable for cabinet mounting and outdoor installation.

Product information
The TBR22 sensor was developed by VTICorp (Viet Nam). It continuously measures and transmits temperature data to central software that provides real-time temperature values and alarm states, instantaneous and trend graphs, abnormal-temperature lists to support maintenance without power interruption, geo-location of measurement points, statistics and configurable reports, and mobile monitoring (iOS/Android) for quick responses.

Outstanding advantages

• Direct installation on equipment and measurement points, including on sources up to 500 kV.
• Power options: induction power from the measured conductor (current ≥ 5 A) or replaceable CR3032 battery (battery variant).
• Long battery life: typically up to 2 years for battery version depending on usage profile.
• Wide measuring range: -10°C to 120°C with ±1°C accuracy, enabling precise thermal statistics for system assessment.
• Provides operational parameters including power, thermal and ambient conditions.
• Humidity measurement up to 100% with ±2% RH accuracy.
• Operating conditions: -10°C to 80°C, humidity up to 100% RH.
• Ingress protection: IP65 (IP68 depending on variant/conditions). RoHS 2 certified.
