Current monitoring sensors

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

Current monitoring sensors show you how much energy you’re using in real time

Most businesses and households are making efforts to reduce the amount of electricity they use, for environmental reasons as well as financial ones.

Our wireless, energy-harvesting current sensors measure real-time energy usage at a machine, room or zone level, so you can:

currentsenmon

Access live data to see where energy is being used

currentlive

Track use over time to identify where you use and waste the most energy, allowing you to find energy savings

assetswitch

Ensure critical assets are functioning correctly and automatically switch off assets when not in use

As a trusted partner to some of the world’s leading businesses, we provide compliant, cost-effective technology solutions that offer the very best performance and reliability.

How our current monitoring sensors work

Our wireless CT clamps measure and report AC current. Single-channel clamps measure the electrical current flowing in a single channel, while three-channel clamps measure current in three separate channels.

Because they simply clip around cables, there’s no downtime or disruption. They also harvest energy from the measured conductor so there’s no need for batteries or wiring.

Data is sent wirelessly and securely from our sensors to any number of receivers. Because our technology is platform agnostic, the data from our sensors can be integrated into any software or platform. It can also be used to automate local control systems, or feed directly into an existing building management system.

How our current sensors work

Features

Current sensor: one channel

  • Measures current (50Hz or 60Hz) every 30 seconds in a single channel
  • Wireless and self powered
  • Measurement ranges:
    1A–60A (+/- 0.1A or 2%, whichever is greater)
    2A–200A (+/- 0.1A or 2.5%, whichever is greater)

Current sensor: three channels

  • Measures current (50Hz or 60Hz) every 30 seconds in three separate channels
  • Wireless and self powered
  • Measurement ranges:
    1A–60A (+/- 0.1A or 2%, whichever is greater)
    2A–200A (+/- 0.1A or 2.5%, whichever is greater)
    2A-600A (+/- 1A or 3%, whichever is greater)

Technology

Where possible we use low-latency, highly-durable channels and protocols, which means the infrastructure used to collect and forward data is easy to scale.

  • We use EnOcean’s internationally approved wireless protocol, designed for reliable transmission in systems with numerous sensors
  • The sensors communicate data via the EnOcean wireless radio protocol
  • Manufactured in the UK to meet the highest quality and environmental standards and global regulatory requirements
  • Our products are tested internally and approved by third-party test bodies to ensure they are reliable, robust and compliant
mini-series

Integration

Our sensor technology is platform agnostic, so data from our sensors can be integrated into any software or platform, connected directly to smart controllers or fed directly into building management systems.

  • Our smart gateway converts sensor data into industry-standard MQTT format and makes it available locally or via the cloud
  • Data is transmitted via a wired ethernet cable, or wirelessly via WiFi or LTE (4G)
  • Ready-made connections with IBM Watson, Microsoft Azure, AWS IoT Core* and Google Cloud IoT platforms*
