Wireless AC Current Meters

Remotely monitor energy use with plug-and-play sensors.

You can install Monnit ALTA^® Wireless AC Current Meters 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, and 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 a machine needs maintenance, is nearing the end of its service life, or has an unexpected power supply issue. These current sensors are also ideal for submetering.

Large or Small, Track It All

Deploy Monnit 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. The ALTA Industrial 150 and 500 Amp AC Current Meters feature detachable leads with M12 5-pin connectors, which are ideal for easily installing the current transformers (CTs) in an electrical panel.

Explore Monnit's portfolio of current meters below and discover the right solution for your business or facility.

Wireless 20 Amp AC Current Meters

Simplicity saves.

The Monnit ALTA^® Wireless 20 amp AC Current Meters remotely monitor your smallest power consumers. These sensors provide data on energy draw to help you lower costs and improve machine health by identifying and predicting maintenance needs.

Get Amperage Alerts

If power use rises or falls outside of user-set limits, the sensor alerts you via text, email, or call. Like all ALTA Wireless AC Current Meters, these 20 amp sensors can also issue energy status updates.

Turnkey Install

Install an ALTA Wireless AC Current Meter within 15 minutes: mount or affix the housing, then wrap the current transformer around the “hot” wire of a two-wire power system.

The ALTA 20 Amp Current Meter is offered in a discreet enterprise-grade model or weatherproof industrial housing, making either an excellent fit for business and machine monitoring. Save money and prevent downtime with one of the sensors below.

WARNING: This AC Current Meter is for monitoring AC voltage only. Do Not Use with DC voltage.

Wireless Voltage Detection - 200 VDC

Keep an eye on equipment power

Machine operators and facility managers have a second set of eyes in Monnit’s 200 VDC wireless sensor. This wireless voltage sensor tracks power sources or monitors the on/off status of equipment and machines, as well as battery levels.

Based on user settings, the presence or absence of voltage triggers the sensor to send an alert via text, email, or call. Know battery health or the operational status of industrial vehicles, ATVs, adapters, PV solar equipment, and other equipment needed by thousands of businesses.

Three sizes of detection

Three models are offered, ensuring a fit for virtually any business. Choose from a small CC sensor, enterprise-ready AA battery-powered sensor, or a weathertight industrial-grade device.

Whether you’re across town, or the country, the sensors below will keep you in touch with your equipment’s voltage status.

Wireless Voltage Meters 0-500 VAC

Have absolute power? Know absolutely.

Monnit’s 0–500 VAC voltage meter is an easy-to-deploy wireless interface for measuring voltage.

Within 15 minutes, this sensor can be mounted, connected to a machine, and configured. The meter then monitors potential differences between two electrical points at user-determined intervals. If it detects voltages that have fallen below or risen above user-set thresholds, the user is alerted via email, text, or call.

More ways to monitor voltage

This 500 VAC voltage meter is available in a mini (yet mighty) CC battery-operated variant, an enterprise-ready AA battery-powered sensor, and a weatherproof industrial-grade voltage meter. Monnit’s variety supports diverse assets ranging from electrical motors inside a machine shop to backup generators outside.

Start remotely tracking the voltage status of your machines with one of the wireless voltage meters below.

WARNING: Use caution when interfacing to the Monnit Wireless Voltage Meter. Negative voltages,AC Voltages, or DC Voltage exceeding 600V, WILL DAMAGE the electronics of the Monnit Wireless Sensor. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.
