Energy Monitoring from FourJaw
Unlike a standalone Energy Monitoring solutions, FourJaw combines Energy Usage Data and Machine Usage Data to drive sustainable, productive and profitable manufacturing:
Understand and track energy usage
By machine, cell, production line or factory, in real-time and over time.
Drive efficiency and reduce costs
Understand which machines waste energy in downtime.
Support sustainable manufacturing
See how energy usage translates to costs and carbon footprint to motivate change.
Energy + Productivity Monitoring = Sustainable, Efficient, Profitable Manufacturing
Why use FourJaw Energy Monitoring?
By combining energy usage data and machine usage data, FourJaw's Energy Monitoring feature provides a number of financial, process, cultural and environmental benefits.
Financial
Understand the cost of energy used by machine, cell, production line or factory.
Productivity
Understand whether energy is wasted on downtime or consumed by productive work.
Process & Systems
Make informed decisions about processes to drive energy-efficient and productive manufacturing.
Behavioural
Drive behavioural change across the factory to reduce wasted energy and support continuous improvement efforts.
Sustainable
Understand your carbon footprint by machine to support your sustainable manufacturing initiatives.

Get Installed in 3 Easy Steps
1
Install Hardware
Simply supply power to the MachineLink hardware, then attach a sensor to your machine’s power cable. It’s as simple as ‘Clip, Plug and Play’.
2
Connect To WiFi
Connect the MachineLink hardware to your shop-floor WiFi network. Or if you’d prefer you can connect via an Ethernet connection.
3
Unlock Productivity
Log in to the secure web app and within 10 minutes** or so of the hardware being online you will have real-time data visibility to start identifying and eliminating inefficiencies.
Frequently Asked Questions
-
How Accurate is FourJaw Energy Monitoring?
-
The accuracy of the energy use values will depend on the accuracy of the power factor of your machines plus the accuracy of the current clamp measurement.
FourJaw current clamps have been independently tested and in the range of 1 - 100 Amps, the accuracy is +/- 5.5%.Energy monitoring in this way is accurate enough to show you trends and anomalies. For applications requiring more accurate data on energy monitoring, you can scale the energy use stated by FourJaw to that given by an accurately calibrated ammeter by changing the power factor of the machine.
-
Will FourJaw Energy Monitoring work on all my machines?
-
Current Range
The current clamps we use work on any machine where each phase has a current draw from 50mA-100A.
3-phase or 1-Phase
If your machine uses 3-phase electricity, simply clamp around one phase of the main incoming supply and make sure the machine has 3-phase chosen within the FourJaw energy settings. If 1-phase, clamp to either the live or neutral, but not both at the same time, and choose 1-phase in settings.
Age, Make and Model
The age, make or model of the machine doesn’t impact the efficacy of the FourJaw platform.
Exceptions
Sometimes to optimise productivity and energy monitoring at the same time, the current clamps need to be moved to be on both the power supply and a particular spindle. If this is the case, our support team will work with you to get this right. -
How do you calculate Energy Used, Cost and Carbon Footprint?
-
We calculate power usage as follows:
Single Phase
P = pf × I × V / 1000
In this formula, the amount of power - P (in kW) is equal to the power factor of the load (pf) multiplied by the phase current measured in Amps (A), multiplied by the Root Mean Square (RMS) line-to-line voltage (V), and divided by 1000.
3-Phase
P (kW)= √3 × pf × I × V /1000
The power - P (in kW) equals the square root of three (√3) multiplied by the power factor (pf) multiplied by the current in Amps (A), multiplied by the Root Mean Square (RMS) line-to-line voltage (V) divided by 1000.
To calculate the cost:
We multiply the power used by the cost per kWh given on the settings page.
To calculate the carbon footprint:
We multiply the power used by the kilograms of carbon equivalent per kWh given on the settings page. This is defaulted to the UK government-approved value. -
