PHONO Concrete Compaction Sensor

Enhance concrete quality with the PHONO Concrete Compaction Sensor

Our PHONO sensor monitors concrete compaction easily, even in hard-to-reach formwork areas. This minimises the risk of gaps between the concrete and any adjacent components.

Concreting against existing structures can present challenges. Our concrete compaction sensor provides accurate data in real time so you can act accordingly to minimise the risk of any damage.

Monitoring compaction levels during the concreting process can reduce test drilling and potential rework. Instead of drilling a test hole, you can use the sensor to check for the presence of concrete. This will help you save time and resources, whilst ensuring a high concrete quality.

The concrete compaction sensor also allows you to measure compaction levels from below with concrete pumps. The sensor can be integrated into our formwork systems or embedded into the pours.

PHONO in action

  • Precise, low-cost ultrasonic sensor

    The concrete compaction sensors work by using high-frequency sound pulses. This determines whether it is surrounded by air, liquid or concrete to understand the degree of compaction.

  • Easy to read

    The results from the compaction sensor are displayed in a traffic light form. Each measuring point can be read quickly, allowing you to act immediately if deviations occur.


We offer the PERI InSite Pressure Sensor in two variants. You can choose between a completely new set with a communication unit, or an add-on for your temperature set if you already have one.

Set 1:

  • 1 Technical Cabinet 
  • 1 Main Unit integrated into the Technical Cabinet 
  • 1 Pressure Node
  • 4 Pressure Sensors 
  • Accessories (cables, spare parts, etc.) 


Set 2:

  • 1 Pressure Node
  • 4 Pressure Sensors
