Wireless current monitoring sensors

Measure energy consumption at a circuit, zone or machine level, in real time

Our wireless current sensors (CT) measure the alternating current (AC) and report the average of 5 measurements every 30 seconds.

The small, energy-harvesting devices use ultra-low power wireless and battery-less technology making them easy to install and very low maintenance. They simply clip around a cable and the wireless transmitter attaches outside the panel for reliable wireless data transmission. They can easily be fitted inside a machinery panel, distribution panel or other suitable location.

Wireless, self-powered current sensors

They simply clip around a cable and measure the electrical current, so there’s no interruption to the electrical supply

Access real-time data locally or in the cloud

Using our Smart Gateway, data is encrypted and sent locally or to your chosen cloud platform via MQTT

Features

  • Sensors measure AC current (50Hz or 60Hz). Reports average of 5 measurements every 30 seconds
  • Single-channel (single-phase) clamps measure the electrical current flowing in a single cable, while three-channel (3-phase) clamps measure current in 3 individual cables. Normally you will find single-phase systems in, for instance, households and office buildings. In the industry and for heavier machines, three-phase electric power is typically used.
    • One channel measurement ranges:
      1A–60A (accuracy +/- 0.1A or 2%, whichever is greater)
      2A–200A (accuracy +/- 0.1A or 2.5%, whichever is greater)
    • Three channels measurement ranges:
      1A–60A (accuracy +/- 0.1A or 2%, whichever is greater)
      2A–200A (accuracy +/- 0.1A or 2.5%, whichever is greater)
      2A-600A (accuracy +/- 1A or 3%, whichever is greater)
  • Self-powered using ultra-low energy from the measured conductor, so there’s no need for batteries or wiring
  • Clamps simply clip around cables with no interruption to electrical supply. The wireless transmitter attaches outside the panel for reliable wireless data transmission
  • Transmit data wirelessly and securely – using AES-128 encryption – via EnOcean wireless protocol, which uses internationally approved, licence-free ISM bands
    • 868 MHz for Europe (RED)
    • 902 MHz for North America (FCC) and Canada (IC)
    • 928 MHz for Japan (ARIB specification)
  • EnOcean Equipment Profile (EEP): D2-32-00, D2-32-02
  • No recurring fees. Access the data through your chosen platform, without any additional costs from Presssac.
  • Manufactured in the UK to high-quality and high-safety specifications, they are subject to rigorous testing procedures.
  • Packaging unit: single
