Accuenergy New BAS Sensor Line for Smarter Building Automation

Toronto, ON - August 26, 2025 – Accuenergy Inc., a global leader in power and energy measurement solutions, unveils the initial release of its BAS instruments, including pressure, relative humidity, and temperature sensor models. This marks an important milestone in Accuenergy’s expanding sensor line for building automation and control.

“Accuenergy brings the unique element of having a deep well of existing technology, talent, and scalability,” said Chad Schwenn, BAS Business Unit Director at Accuenergy. “We have made a name for ourselves designing feature-rich measurement products while still maintaining our value relative to the market. Accuenergy’s BAS Sensor lines will continue these traditions.”

Meeting the Demand for Smarter BAS

As building automation systems evolve, facility operators are under increasing pressure to balance energy efficiency, regulatory compliance, and occupant comfort. Rising energy costs, stricter indoor air quality standards, and the adoption of intelligent buildings are driving demand for more precise, reliable data.

Traditional BAS sensors often fall short, offering limited accuracy, drifting over time, and relying on slow or noisy signals that disrupt stable HVAC control. These shortcomings not only waste energy but also lead to comfort complaints and higher maintenance costs.

Accuenergy’s new BAS sensor portfolio directly addresses these challenges, delivering high-accuracy differential pressure, humidity, and temperature measurements that integrate seamlessly into modern BAS applications. Compared to older technologies, Accuenergy sensors provide fast response times, better long-term stability, and consistent performance in demanding conditions.

By enabling more dependable data collection, these sensors support smarter automation strategies such as demand-controlled ventilation, adaptive reset schedules, and predictive analytics, helping facility managers reduce operating costs, optimize HVAC performance, and improve indoor environments.
