Tensio System Features

tensio intelligent sensors

Tensio Sensors Measure the Live Load Supported by Your Roof

Our intelligent sensors (IoT) are installed by one of our engineers on the steel structures inside your buildings to measure the stretching of the steel caused by the load of snow, water and ice on the roof of your buildings. 

Data Is Compiled in the Tensio App and Cross-Referenced With Weather Forecasts

Powered by artificial intelligence (AI), the Tensio web app tells you whether or not certain locations on your roof require snow removal based on their current load and the hourly weather forecast for the next few days. You can therefore visualize and monitor the structural stress of your buildings' structure in real time.

A Preventive Alert Is Sent as Soon as a Limit Exceedance Approaches

When installing your Tensio system, a structural engineer determines the capacity limits for each roof location based on a multitude of factors (snow accumulation history, roof geometries and heights, low walls causing snow triangles, wind direction, etc.).

Fast, Low-Intrusive Installation

Installation of a Tensio system takes an average of one day. Thereafter, it takes 2 to 3 weeks for the engineering analysis and configuration of your Tensio software. Delivery times vary according to the season.


Tensio Systems Can Be Installed All Year Round, Regardless of the Season

Even in winter, it's possible to install a Tensio system, as long as we can access the roof to set the collectors to 0. However, our operations are greatly facilitated during the summer season. 

1. Installation of Tensio Sensors

An installer comes to your building to install the sensors in the ceiling structure. The sensors are installed directly on the structure of your building (beams and joists) in the locations previously identified. When the sensors are installed, the installer makes a survey of your building's structure, which is passed on to the engineering team.

The procedure is non-intrusive and does not disrupt your activities. 

2. Analysis of Your Buildings’ Actual Capacity

Using the data collected by the installer, our structural engineer determines the capacity limits of each section of your buildings where Tensio sensors are installed. 

The engineer then determines the relationship between steel deformation and roof loads, specific to each location.

3. Setting up Your Tensio Account and Training

Our team sets up your company's account in Tensio, including preventive alerts, and trains your users on the application.
