ACREL Wireless Temperature Sensor for Switchgear Monitoring

The ACREL Wireless Temperature Sensor for Switchgear Monitoring is intended for temperature monitoring in electrical switchgear and associated equipment. It is part of Acrel's ATE series of wireless temperature measuring sensors, which are designed for real-time transmission of temperature data from monitored heating points.

The ACREL Wireless Temperature Sensor for Switchgear Monitoring uses wireless transmission at 433-470 MHz and has a manufacturer-specified transmission distance of up to 150 metres. Its built-in battery avoids the need for a separate wired power supply at the sensor location.

The sensor provides a wide temperature measurement range of -50 °C to +300 °C and is supplied with a 2 metre cable. Acrel specifies a service life of approximately 5 years.

How it works

• The sensor measures temperature at the selected heating point within the electrical equipment.
• The measured temperature data is transmitted wirelessly using the 433-470 MHz frequency range.
• The specified wireless transmission distance is up to 150 metres.
• Temperature information can be received by compatible Acrel equipment and can be passed to a remote monitoring system.
• Acrel states that product data can be transmitted to its IoT platform through suitable gateways for access from connected devices.

Why choose this product?

• Wireless monitoring reduces the need for signal cabling between the sensor and receiving equipment.
• Wide temperature range of -50 °C to +300 °C supports monitoring across a broad range of operating conditions.
• Built-in battery provides power at the sensor without a separate supply connection.
• 150 metre transmission distance provides flexibility when locating sensors and receiving equipment.
• 2 metre cable allows the sensing point to be positioned where temperature measurement is required.
• The sensor is designed specifically around temperature monitoring applications in electrical switchgear.
