Wireless AC Current Meters

Plug-&-play sensors remotely monitor energy use

Monnit’s Wireless ALTA® AC Current Meters install within 15 minutes to provide insights on machine health or system performance via current usage. These sensors track the minimum, maximum, and average RMS current, as well as amp hours. If power consumption spikes or plummets beyond user-defined limits, an alert is sent via text, email, or call.

Fluctuating power consumption often indicates that: a machine needs maintenance, is nearing the end of its service life, or an unexpected supply issue. These current sensors are also ideal for submetering.

Large or small, track it all

Deploy Monnit’s Wireless AC Current Meters indoors or out—choose from enterprise-ready or weatherproof, industrial-grade sensors in 20 amp, 150 amp, and 500 amp models.
