Acrel Wireless Temperature Monitoring Devices: Safeguarding the Operation of High- and Low-Voltage Switchgear

Wireless temperature is suitable for 3-35kV indoor switchgears, including built-in switchgears, handcart switchgears, fixed switchgears and loop-net switchgears. It is also suitable for 0.4kV low-voltage switchgears such as fixed switchgears and drawer switchgears. The wireless temperature sensors can be installed at any heating point in switchgears, the device utilizes the wireless data transmission technology for real-time transmission of monitored temperature data. In addition, it can be transmitted to display device or remote intelligent monitoring system.

The ARTM series wireless temperature monitoring devices are suitable for a wide range of applications, including 3–35kV indoor switchgear (such as central-mounted, withdrawable, fixed, and ring main units) and 0.4kV low-voltage cabinets (fixed or drawer-type).

Key Product Highlights

Compact Design: Sensor dimensions are only 25.82 x 20.42 x 12.80 mm, allowing for easy installation even in confined cabinet spaces.

Temperature Monitoring: Measures temperatures from -50°C to +125°C with ±1°C accuracy, covering both high- and low-temperature scenarios.

Wireless Transmission: Supports FSK wireless communication, ensuring stable, low-latency data transmission.

Smart Power Supply: Powered via CT induction (starting current ≥5A); requires no additional wiring and is maintenance-free.

Authoritative Certification: CE-RED certified, guaranteeing product quality and safety.

The system comprises wireless temperature sensors, a receiver, and display/monitoring equipment. Sensors are mounted directly onto heat-prone contact points within the cabinet; they transmit real-time temperature data wirelessly to the receiver, which then relays the information to a display unit or power monitoring system, ensuring continuous, 24-hour temperature monitoring.
