Our bestselling wireless current sensors (CT) simply clip around a cable and measure the alternating current (AC). The small, energy-harvesting devices use ultra-low power wireless and battery-free technology, making them easy to install and very low maintenance. They can easily be fitted inside machinery or equipment, a distribution panel or other suitable locations.

Get accurate, reliable current measurements

Wireless CT sensors measure electrical current (AC: 50Hz or 60Hz) and report an average every 30 seconds

Wireless and self-powered for easy install

The sensors simply clip around a cable and self-power by drawing an ultra-low charge from the measured conductor, so there’s no need for batteries or wiring.

Access near real-time data locally or in the cloud

Energy consumption data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.

• 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.
