Pressure Sensor – Preparation and connection
Before starting installation, check sensors, housing and the membrane for damage and
bubble-free filling to transfer the pressure from the membrane to the sensor. After ensuring
that the Node has sufficient battery status and signal quality the pressure sensors can be
installed.
When decided where to place the sensors, make sure that you place the sensors in correct
order from the bottom e.g. position T1 followed by pos. T2, T3, T4. See figure 5.
Before drilling the holes for the sensors, check again that there is enough space for the
sensor housings.
Mark the center of the hole with the template and pre-drill with a 3 mm. Then drill an opening
in the formwork skin with a 50 mm hole saw.
Before inserting the sensor with housing into the opening, both must be greased. For this
purpose, we recommend commercially available Vaseline.
Check that the sensor and housing are seated correctly and fix it with three screw to the
formlining. Proceed in the same way when mounting the other sensors. When all the sensors
necessary for the measurement are installed, connect the sensors to the Node using the bus
connection cables as shown in the figure.

Starting the measurement
Make sure that the Main Unit is turned on and connected to the mobile network.
Select a project and a dashboard in the Insite web application and create a widget for the
corresponding node.
