Wireless current sensor devices
Measure energy consumption at a circuit, zone or equipment level
Power up your energy management platform
Pressac wireless current sensors (CT) offer a cost-effective solution to enhance the functionality of your energy management system. Whether your platform aims to monitor energy consumption, machine condition, or energy efficiency, these devices provide all the data you need.
Elevate your IoT platform’s capabilities and build an easily scalable, plug-and-play offering.
Why should I invest in Wireless current monitoring sensors?
Get accurate, frequent current measurements
Wireless CT sensors measure electrical current (50Hz or 60Hz) and report an average every 30 seconds.
Wireless and self-powered for easy installation
Using energy-harvesting technology, the sensor draws a charge from the conductor, eliminating the need for batteries or wiring. Install outside machinery, distribution panels, or other locations in seconds.
Access real-time data locally or in the cloud
Data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi through an MQTT broker or ready connections to AWS and Microsoft Azure. No subscriptions or recurring fees.

Technical Specifications
Features
- Clamps simply clip around cables with no interruption to electrical supply. The wireless transmitter attaches outside the panel for reliable wireless data transmission
- Sensors measure AC current (50Hz or 60Hz). Reports average current 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
Range
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)
Wireless communication
- 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
- Transmit up to 30 metres in buildings and 300 metres in free field
Power
- Self-powered using ultra-low energy from the measured conductor, so there’s no need for batteries or wiring
