    Plug & play sensors remotely monitor energy use

    Monnit’s Enterprise AC Current Meters installs quickly 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.

    Monnit’s AC Current Meter measures the RMS current of an alternating current (AC) system using a current transformer (CT) that wraps around the ‘hot’ wire of a two wire (hot, common, ground(optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the iMonnit system. The iMonnit system is capable of generating watt hour or kilowatt hour readings as well. The AC Current Meters are available with an option current transducers;

    • Low Current: 0-20 amp 
    • Medium Current: 0-150 amp


    Get amperage alerts

    To measure current, clip the CT around only a single wire of the AC system (clipping around a hot and neutral wire at the same time will result in 0 current readings). After the sensor powers on and connects to the gateway it will begin taking measurements based on the averaging interval (5 seconds default). It will report data to iMonnit every heartbeat or if the current goes outside of the aware thresholds set in iMonnit. The sensor reports amp hours, max RMS current, min RMS current, and average RMS current. iMonnit can also generate watt hour or kilowatt hour readings if a default RMS voltage is set in iMonnit. The AC Current meter can also:

    • Data logging for accumulated amp hour readings 
    • Can notify based on current levels or changes in current levels 

    The AC Current Meters come standard with two replaceable AA batteries. The typical battery life is approximately 10 years.

    WARNING: This AC current meter is for monitoring AC voltage only. Do Not Use with DC voltage.


    Features:

    • Impressive wireless range of up to 1,200 feet through walls
    • Frequency-hopping spread spectrum (FHSS)
    • Improved interference immunity
    • Improved power management for longer battery life
    • Encrypt-RF® Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
    • Stores 2000 to 4000 readings if gateway connection is lost (non-volatile flash, persists through the power cycle)
      • 10-minute heartbeats = ~ 22 days
      • 2-hour heartbeats = ~ 266 days
    • Over-the-air updates
    • Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email

    Monnit Gateway Options

    An integral component of any IoT network is the gateway. A gateway device allows for data from sensors to be transmitted to the iMonnit software platform.


    Monnit Ethernet Wireless Gateway 4

    Monnit’s Ethernet Gateways allow your Monnit Wireless Sensors to communicate with the iMonnit™ Online Wireless Sensor Monitoring and Notification System without the need for a PC. Simply provide power and plug the gateway into an open Ethernet network port with an internet connection. It will then automatically connect with our online servers, providing the perfect solution for commercial locations where there is an active internet connection.

    Monnit 4G + Ethernet IoT Gateway

    The ALTA® by Monnit Wireless IoT Gateway combines a 4G LTE CAT-M1/NB2 cellular engine and Ethernet platform with Monnit’s wireless access point network to aggregate and communicate data from Monnit ALTA Wireless Sensors. The ALTA IoT Gateway allows ALTA Sensors to operate on the world’s leading cellular networks and stay connected to the Internet. The gateway uses AC main power but also has redundant power through a battery backup lasting up to 60 hours.

    To meet the global demand for enterprise IoT deployment, the IoT Gateway communicates with the cloud-based iMonnit® monitoring software via cellular transmission, making it ideal for remote locations or where the Internet isn’t available. The RJ-45 Ethernet jack allows local device configuration, diagnostics, and connectivity backup. The IoT Gateway is instrumental in sending sensor notifications via text, email, or call if user-defined conditions are met or exceeded.

    *Circuits cannot withstand negative voltage. Please take care when installing batteries.

    **CTs are inherently less accurate at or below 10% of max range. For best calibration results calibrate at a current between 30% and 90% of max
    accurate range.

    ***Because of a diode inherent to the hardware, the sensor is incapable of reading between 0 and the deadband value. This diode also creates an
    offset. To account for this, the firmware uses offset compensation
