Measure moisture without destructive sampling
Until now it's been impossible to know the moisture levels behind a sealing layer without damaging the construction. It has been impossible to know the dry-out status of your newly applied screed without drilling in it. That changes today.
We develop industry-leading moisture sensors for different applications
Standard Moisture Sensor
Our Standard Moisture Sensor can measure relative humidity in walls and floors. It is a passive and super thin sensor (like a sticky label), which makes it affordable. The components in the system are: The sensors installed, a scanner used for scanning the sensor values, a mobile phone application connected to the scanner for read out of values and a cloud service where all your installations, sensors and sensor values are stored for future analysis and visualization.
The application areas for the Standard Moisture Sensor are primarily for quality assurance, quality control and for damage evaluation. Below are the typical scenarios, but there are many, many more application areas:
Moisture measurements in screed
Our Screed Sensor helps you to take control of the dry out process of screed. Before the screed is applied, the Screed Sensor is glued (self-adhesive) to the floor so it ends up approximately in the middle of the screed. No other moments are required. After the screed had been poured out, the floor can be scanned once a week and a dry out curve is created in the cloud service. In the cloud service the time until the dry out has reached the required level can be estimated.
Apart from knowing when the screed is dried out, another advantage is that also deviations from the expected dry out curve will be detected. For instance if the measures on a construction site are not followed, or there is additional moisture added in parts of the building, this will be immediately detected by the site manager and extra drying efforts can be installed to keep the important milestones in the construction schedule.
Concrete data
The Concrete Sensor has two major application areas, one is to follow the dry out process in concrete slabs. This process is relatively long, and the prediction made by the concrete supplier, regarding the dry out time, is uncertain simply because the conditions on the construction site are unpredictable. Using the Concrete Sensor, you can have full visibility of the dry out process. Today you are probably using expensive measurements to understand the moisture level, these can be almost eliminated, which will reduce your cost at the same time as your time schedule’s reliability will increase.
The second application area is within the pre-fabricated concrete elements that now can be tracked from leaving the supplier to installation in the building. This way the moisture level can be tracked and quality assurance maintained throughout the journey of the pre-fab elements.
In future generations of the sensor, we will be adding temperature measurements besides the measurement of moisture levels.
Roof Sensors
Flat roofs are subjected to high loads day in, day out: Thermal influences such as heat, UV radiation and cold, moisture resulting from rain, standing water and building moisture, mechanical stress of the supporting structure from exposure to wind, ice and hail, work performed on superstructures and site inspections of the roof surfaces or technical defects in workmanship inevitably lead to ‘small’ leaks in the roof cladding over time.
The Roof Moisture Sensor is an important component in the roof maintenance activities. If you are building a flat roof for a customer, the built in Roof Moisture Sensors will enable a much higher visibility of the moisture status of the roof and thus a more efficient maintenance.
This will result in earlier detection of moisture leaks, which in turn leads to lower maintenance cost, and better energy preservation (once a flat roof starts leaking, the energy balance changes dramatically).
We are in cooperation with Nordic Industrial Services, who are the worldwide reseller of the roof sensor.
Frequently asked questions
We now have an FAQ list that we hope will help you answer some of the more common ones.
Are they simple to install?
How does the sensor work?
How do you know where each sensor is located?
The sensor is passive and its only purpose is to balance in moisture level with its surroundings in order to determine said moisture level. To localize the sensor and connect the measured value to a specific sensor we have developed an app where you easily can see where sensors are installed on a drawing of the measurable object. Before measuring you choose the sensor you are going to measure, and the result is saved to the chosen sensor. The value is also uploaded to InviSense Cloud for compilation and overview of the results.
Is anyone able to measure?
Yes, when you place a sensor in InviSense cloud you also choose the materials it will be in contact with. There are limits connected to these materials, which the scanner use to indicate the risk level of the materials. This is indicated with colors:
- green = below risk level
- yellow = should be kept an eye on
- red = below the limit of the material of risk-free moisture level
This is a big improvement compared to current instruments which require extensive experience and knowledge regarding the moisture characteristics of different materials.
How long does the sensor last?
Is it possible to get similar measurements with existing technology?
Where do I buy the sensor?
What does it mean that the sensor is passive?
It means that it isn’t limited by any battery time, doesn’t emit any radiation, can be extremely thin (less than 0.1mm) and has to be measured by InviSense moisture scanner where the sensor is located.
Do you have any limitations?
Is it possible to see trends over time?
Yes, with the help of our user friendly InviSense Cloud all measurement data is saved and connected to each sensor. This means that it’s possible to see how a single sensor is affected. This could mean that new knowledge is created over time and with that it would be possible to make decisions regarding material choices suitable for different cardinal directions, applications and climate change.
Where is it suitable to install a sensor?
What is the primary application?
Things sometimes go wrong when building. According to several of the insurance companies we have contacted most damages happen within 6 to 12 months. Small damages that aren’t noted during the warranty period but become costly over time. We are a complement to today’s inspection routines, where are sensors are read during final inspection, two-year inspection and five-year inspection. That way you are able to notice damage in time, and the fault can be corrected by the responsible party. When you suspect moisture damage you are also able to more quickly determine whether it’s damaged or not and the extent of the damage. You can then spend the time determining the cause of the damage and decide which corrective actions that should be conducted. If you also install sensors in a repaired construction you will be able to follow up if the fault is corrected.
