The R-Link watch has been developed to assess and manage hand arm vibration (HAV) risks more easily and effectively.
The R-Link® smart watch is new generation of workplace wearable technology which is designed to help workers monitor the risk of exposure to vibration. R-Link informs the wearer of their exposure levels by calculating and displaying their HSE HAV risk assessment exposure points in real-time. Sound and vibration alerts inform the wearer if their personalised exposure thresholds have been exceeded.
R-Link features ground-breaking technology to simultaneously assess exposure risk using; pre-defined tool vibration magnitude and vibration magnitude sensed by the wearer at the wrist.
Either of these methods can be used to display HAV risk exposure points and both types of data are stored online for analysis by employers.

R-Link is the successor to our established HAVWEAR wearable which has been trusted by over 100,000 workers in the UK. We've built upon decades of experience in developing risk prevention solutions, and enhanced the powerful HAVS monitoring capability of HAVWEAR, to launch a R-Link and protect your workforce from an entire risk environment, while optimising productivity.
“While we were using R-Link, I found the system very easy to use, the information received indicated the need to alter working methods & choice of tools to be used, it also highlighted that the tools we thought would be the highest values were not because of the use of clamps. Using the system showed that generally we were under the HSE calculator levels".
Bradley Allen, HSQE Manager
“One such example was by having access to more accurate exposure data, including real-time vibration magnitudes, we could assess which tools were best for particular applications. We consider Hilti breakers to be one of the best available and realised through the Reactec data we could replace a Hilti breaker TE1000, used for a wide range of applications for a larger TE2000. Even though it was more expensive it helped complete work tasks quicker and exposed the operator to less exposure during use so it was a win-win for project efficiency and worker health”.

“Setting up the system was straight forward and simple including the tagging of tools. The tool operators found it easy to use making sure to switch off HAVWEAR during breaks. I also prefer wrist worn monitors instead of tool mounted devices as they used to get damaged or knocked off the tool. I also like how seamlessly and quickly the data is downloaded to the analytics platform once the watches are docked back onto the Docking Stations. This removes the need for paper work, saving time and money and it’s reassuring that the data is much more accurate than estimating with a paper based system, especially for trigger times. I find the Analytics Platform user friendly and the data easy to understand which enables me to see if there are any issues with tools or operator usage. The Sensed Exposure Points (SEP) data is a definite advantage of the watch as it provides a more accurate indicator in terms of vibration magnitudes and exposure experienced by our operators. Without SEP you just have tool trigger time data which the watch also provides but having both data sets is a big advantage. Using SEP data within the analytics we soon identified a number of tools that we investigated further in terms of their programmed vibration magnitudes. For example some flex polishers had estimated vibration magnitudes of 2.4m/s while SEP data reported them at 9m/s. The data can also help direct us to review other tool makes and models that are lower vibration. Lastly, HAVWEAR through monitoring tools, usage and exposure further helps us to meet health and safety compliance”.

The devices themselves are simple to use yet give me fantastic data. The simple traffic light system and vibrations for the operatives gives them zero reason to not know when they have hit their limit. The docking station lighting system is also easy for me to understand . I also appreciate that the system is updated and people don’t just sit on what they have.

Last year we purchased 16 Reactec HAVWEAR watches and 4 docking station in a bid to help us monitor and reduce exposure to hand arm vibration within our workshops. I found the whole package - tool tags, the HAVWEAR smart watch, employee I.D cards and initial set up was easy to implement within the company and the online analytical reports and data that it produces are very detailed but easy to read and understand. Overall this system has effectively helped us to reduce employees exposure and I would highly recommend this product to other companies.

We have been able to see that the amount of time spent drilling (trigger time) is not the only factor that contributes to vibration exposure. Ground conditions and age of the drill are also influences. We knew this already of course, but the beauty of the HAVWEAR system is that we can actually see what a difference these make. “As a field operative, I find using the HAV monitors both easy and informative. The monitors enable us to see the actual vibration exposure in real time. Moreover, it allows us to identify the tools with the highest level of vibration, as well as trends in their use over time. Overall, I believe the HAV monitors are going to be good for us when planning drilling activities.”
How it works
The R-Link smart watch simultaneously at all times gathers HAV exposure data based on two methodologies - TEP and SEP. Only one is displayed to the operator - a choice made at a company level. The data is automatically transmitted to the Reactec Analytics by a docking station or RASOR. Within the Reactec Analytics your choice of exposure assessment method will be reflected in the HAV reports to standard users. Additionally your subject matter experts can view both sets of data to gain unprecedented insight to real use HAV risk drivers.
Tool Exposure Points (TEP) are calculated using the HSE risk assessment Exposure Points system, combining the length of time a tool is in use (trigger time) with the vibration value that is programmed on the R-Link Tag. The validity of the value programmed in the R-Link Tag is a responsibility of the employer to be “representative of the tool use by their operators”. A number of sources for the pre-defined magnitude can be used and the HSE will look for justification of choice.
Sensed Exposure Points (SEP) are calculated at the same time by the same HSE risk assessment methodology except that the vibration magnitude is real-time vibration magnitude as determined by R-Link. The R-Link watch takes a precision measurement at the wrist and corrects this measurement for the transmissibility through the hand. This yields a good real-time approximation of actual risks faced. If SEP is used as the sole assessment it should be done on the basis of being confident that the assessment does not under-assess the vibration magnitude. There is ample guidance from HSE on typical tool vibration magnitudes to allow a determination on the suitability of R-Link sensed vibration magnitude.

Add RASOR to your HAV Management Tool Kit
Assigning a RASOR to either a field supervisor or team member, the RASOR will automatically gather live exposure data from all their teams’ health risk sensors within range, including but not limited to Reactec’s R-Link watch.
The RASOR user and remote management will be automatically alerted to any exposure breaches for immediate over the shoulder intervention.
The RASOR transmits exposure data along with location information to the cloud based Reactec Analytics every 15 minutes so remote supervisors can have full visibility of their team’s location and exposure risk levels.
Reactec Training Aid
Optimise in real-time tool operator productivity and risk, with the Reactec Training Aid App
The Tool Training App means supervisors can better manage productivity and risk than previously considered possible.
By combining the RASOR training aid and the R-Link watch, supervisors can proactively optimise tool choices and usage by training colleagues to.
- Improve operator tool technique
- Better assess tool condition
- Ensure the best tool for the job
The tool operator can change their tool technique such as grip, push force, etc to see if the effect increases or reduces their exposure risk.
While standing alongside a tool operator who is wearing R-Link, the RASOR user can view the rate at which the tool operator’s exposure will be accumulated based on the real time vibration experienced by that operator.
Example of variation in exposure from tool use as shown using the training aid.
If the tool under test has the R-Link Tool Tag attached then the Training Aid display will also compare the real time risk against what is expected of the tool via a simple but powerful traffic light visual aid. The visual aid will identify when the sensed level from R-Link is materially different to the tool tag value.
Note the reading is updated approximately once a second and is not a rolling average over the time since activation. This contrasts with instruments designed to measure vibration dose which average the dose from the start of the test and do not allow for real time analysis of technique.
It should be recognised that the R-Link watch real use data supplied to the RASOR is based on R-Link sensed vibration reading. The R-Link watch sensed vibration uses detected signals from a triaxial accelerometer in the device which are adjusted for transmissibility through the hand to give an approximation of the vibration magnitude incident at the hand. The reading as such does not meet the measurement requirements of ISO8041. However, the methodology is extremely consistent and will readily be able to determine relative risk levels for different uses of a tool or differences between tool types.
