ACREL Wireless Temperature and Humidity Sensor

SKU: AHE100
$213.00Price
ACREL Wireless Temperature and Humidity Sensor is a wireless temperature and humidity monitoring sensor for electrical switchgear, terminal boxes, ring main units, transformer boxes and distribution rooms. It measures temperature from -30 °C to +85 °C and humidity across the manufacturer's stated measurement range, with wireless transmission at 470 MHz. The sensor uses DIN rail mounting and provides a 500 m open-area communication distance, making it suitable for remote environmental monitoring where conventional wired sensors may be less convenient.
Quantity

The ACREL Wireless Temperature and Humidity Sensor is designed for monitoring temperature and humidity in electrical equipment where environmental conditions need to be observed without running individual sensor cables.

It is particularly suited to medium and high voltage switch cabinets, terminal boxes, ring main units, box-type transformers and power distribution rooms. The manufacturer describes the sensor enclosure as designed to provide ventilation while protecting the internal components.

The ACREL Wireless Temperature and Humidity Sensor communicates wirelessly at 470 MHz. The manufacturer's product information specifies a communication distance of up to 500 m in open conditions. Measurements can be sampled at 25-second intervals, with transmission specified at 5-minute intervals on the supplied product page.

How it works

  • The sensor measures the temperature and humidity of the surrounding environment.
  • Measurement data is transmitted wirelessly using the 470 MHz communication frequency.
  • The manufacturer specifies a sampling frequency of 25 seconds and a transmission frequency of 5 minutes.
  • Compatible Acrel receiving equipment can collect the wireless sensor data for monitoring and further system integration.
  • The sensor is installed on a 35 mm DIN rail according to the manufacturer's information.

Why choose this product?

  • Wireless monitoring reduces the need for individual signal wiring between the sensor and receiving equipment.
  • Temperature and humidity measurement provides two environmental measurements from one sensor.
  • Long wireless range - the manufacturer specifies up to 500 m in open conditions.
  • DIN rail installation suits electrical cabinets and distribution equipment where DIN rail mounting is already used.
  • Designed for electrical environments including switch cabinets, terminal boxes, ring main units and transformer boxes.

Benefits

The ACREL Wireless Temperature and Humidity Sensor can help operators monitor changing environmental conditions without having to inspect each installation manually. Wireless measurement can also simplify sensor deployment where installing additional signal cables would be inconvenient.

When used as part of a compatible Acrel monitoring system, sensor data can be collected and made available for centralised monitoring.
