Mounting the Sensors 

Knowing the distance between the sensors is very important. When mounting the sensors, the installer 
must be careful to install the sensors correctly. 

The sensors can be mounted on either rail, in the ceiling or as lowered sensors on a conduit. 

The sensor must be installed above the lane at the height of maximum 2.5 m and minimum 2 m. The angle 
of the sensor beam is 17 degrees. This is the case in the below calculation. 

 

Example of two ultrasonic sensor beams 

 

In a 2-sensor DPO, the following precautions must be taken into consideration: 

-

 

When sensors are installed at maximum height (h),  the distance (m) can be calculated in this way: 
2*h*tan17 = 2*2.5*tan(17 (+2))= 1.72  m 

The (+2) is the maximum allowed deviation of the installation accuracy.  

The equation above implies that the sensors must be installed no closer than 1.72 m to each other to avoid 
crosstalk and false activations. Carlo Gavazzi recommends increasing the result of the equation to 2.0 m to 
make sure you avoid crosstalk and false activations.
