MATHEMATICAL CALCULATION OF INDUCTION LOOPS
Induction loop type calculation: double LOOP SEGMENT
1.- First the room length is set (less 10-20 cm of the total length for other installations).
2.- Please set the preferred segment width (between 2 meters and 5 meters, depending on field loss).
3.- Now the coefficient „X“ can be calculated.
„L“= room length
„S“= preferred segment width
From the table in column „G“, please take the value closest to the calculated value „X“.
The coefficient values P 1 and P 2 indicate the number of segments for both loops.
Calculation of segment width „A“
„L“= room length
„G“= value closest to the calculated value „X“
Calculation of the distance between two segments „B“
Calculation of the shift between the two loops „C“
