Amper Hardware Overview


Before you get started installing your Amper devices, you should familiarize yourself with the various components that make up our machine monitoring solution. This article will provide an overview of the fully assembled hardware set as well as detailed information on each component. It will also cover the hardware options you must decide on before receiving your shipment.

Amper Hardware Overview

Each machine will be monitored by its own individual set of hardware. Each set of equipment will include:

  • One or more Sensor(s)
  • Aggregator
  • Gateway
  • CAT5 Cable
  • Power Supply

These components are assembled together and fastened to each machine. Below is a schematic overview of how the Amper components connect to each other and to your machine.


Note that the above image shows only one sensor connected to the Amper Aggregator. Your machine may require additional sensors to fully monitor the machine's functionality which are plugged into the additional ports on the Aggregator.

Hardware Components


To monitor your machines, Amper collects data on the electrical signals from the machines. The signals are collected by clamping a type of sensor called a current transformer to the relevant wire. To better understand which wire to clamp, see our article Sensor Placement and Installation.


In the picture above are the two versions of the Sensors we provide. The blue sensor (left) is used for wires with a maximum Amperage of 100A and the white sensor (right) is used for wires with a maximum Amperage of 600A.


The Sensors are plugged to a device called the Aggregator (pictured below). The Aggregator is responsible for collecting the signals from the Sensors before sending it to our system. This device is typically placed inside the Machine Power Panel along with the Sensors.


There are two different sets of ports on the Aggregator:

  • 8 Sensor Ports on the top of the device to receive signals from the Sensors
  • 2 CAT5 Ports on the side of the device to connect the aggregator to the Gateway

On the front of the aggregator you will see two sets of LEDs:

  • A single LED in the bottom left corner to signal if the device has power and
  • A row of LEDs at the top to indicate if a sensor is plugged into the port above it

In the picture above you can see that the aggregator's power light is illuminated as well as the LEDs for sensor port 1 and 2 showing that these sensors are properly connected.


The aggregator is connected to our Gateway device through a CAT5 cable. The Gateway is responsible for providing an internet connection to your devices and transmitting the collected data to the Amper system.


The picture above shows a powered on gateway. On the front are two LEDs:

  • Device Status LED (Top Light)
  • Connection Strength LED (Bottom Light)

The Device Status light will either be one of two colors to represent the current state of the device:

  • Blue - Powered On
  • White - Configuration Mode (Wi-Fi Gateways Only)

The Connection Strength Light will show the strength of the connection the device has to the Cellular or Wi-Fi network with the following colors to represent strength:

  • Green - Strong Connection
  • Yellow - Moderate Connection
  • Red - Weak Connection

Amper recommends placing your gateways in a location that provides a consistant Green or Yellow Connection Strength LED. If your devices are showing a Red Connection Strength LED, try and move the device to a higher location or closer to your Wi-Fi access point.

CAT5e Cable

The Gateway and Aggregator are connected by a standard CAT5e cable. Your Amper purchase will include CAT5e cables that we strongly recommend using for your installation. If a cable is damaged and want to get your Devices back on line as fast as possible, you may use your own CAT5e cable but we do recommend using Amper provided cables.

Power Supply

To power all of your devices, a power supply unit is attached to the Gateway. This power supply uses a 120V power outlet and can either be plugged into a standard wall outlet or to an outlet that is a part of the machine.

Hardware Options

Before shipping you Amper hardware, there are a few choices that need to be made that will decide the types of hardware you are shipped.

Sensor Options

For our hardware we provide two different types of sensors, based on the amperage level of the wire.


The picture above shows our two sensors - the blue sensor for wires 100A and below, and the white sensor for wires 600A and below. Orders will include the blue sensor standard unless otherwise noted. When placing your order, make sure to check with your Maintenance or Engineering team to confirm the number of each type of sensor you will need.

Gateway Options

The second choice you will have to make is the type of Gateway you would like to use to connect your machines to Amper - Wi-Fi or Cellular. There are a number of considerations to make before making a choice. Please see our article Connectivity: Cellular vs. Wi-Fi for more information.
