Wireless current monitoring sensors
Measure energy consumption at a circuit, zone or machine level, in real time
Our 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-less technology making them easy to install and very low maintenance. They can easily be fitted inside a machinery panel, distribution panel or other suitable location.
Get accurate, reliable current measurements
Wireless CT sensors measure electrical current (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 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.

Our wireless smart repeater is a cost-effective way to increase sensors’ range, allowing them to transmit data over a larger distance or where obstructions occur.
Measure the ambient temperature in each room, cabinet or zone. The small sensors are wireless and solar-powered sensors, making them easy to install and zero maintenance.
Our three-channel temperature sensors measure temperature at up to three different points, and can be used for water, air or surface temperature measurements.
Our smart gateways receive live data from multiple sensors and securely send it to your preferred on-premise or cloud platform, via Ethernet, LTE (4G) or WiFi. Enabling you to easily integrate sensor data into your systems.
Accurately detect the presence of people sitting around a table. The small, discreet sensors simply stick to the underside of the table and send an instant update when occupancy is detected.
Detect people going in and out of a single doorway. The small sensors are mounted above a doorway and send a message wirelessly each time a person enters or exits through the doorway.
Automatically detect open doors or windows around your building, including doors on cupboards, cabinets and fridges. The small sensors are wireless and solar-powered sensors, making them easy to install and zero maintenance.
Measure the ambient temperature and relative humidity in each room, cabinet or zone. The small sensors are wireless and solar-powered sensors, making them easy to install and zero maintenance.
Measure ambient carbon dioxide (CO2), total volatile organic compounds (TVOCs), particulate matter (PM1/2.5/4/10), temperature and relative humidity, all in a single sensor.
Monitor occupancy, light, sound, temperature and humidity, all in a single sensor. Producing near real-time, highly accurate data which you can use to ensure your room conditions are at optimum levels at all times.
Measure the energy consumption in any single-phase or three-phase cable from 1-600A. Wireless and self-powered, so they’re non-intrusive and maintenance-free.
Monitor the status of any equipment that has a dry contact output, such as UPS status, security systems, fire alarms or air conditioning units. They’re wireless and self-powered, making them easy to install and maintenance-free.
Turn ‘dumb’ meters into ‘smart’ meters. Pulse counters report the number of pulses from electricity (per kWh), water (per m³), or general meters (per count), as well as machinery and equipment with a pulse output.
