Question

Do you have material influence tables for the capacitive proximity sensors such as the CT series ?

Answer

The official answer is that there really is not an official reduction chart available mostly because of the different effects of the materials, thickness, humidity, the trimmer position and such. Even more, the international standard (IEC60947-5-2) which the sensors are tested to and such does not give the rules to calculate such reductions.



There are several factors that can influence range such as target conductivity, humidity and temperature.

Here are some very general correction factors

• Steel 1.00
  
• Surface of water 1.0
  
• Ungrounded Steel(150x150x1mm) .85
  
• Glass (150x150x7.5mm) .55
  
• PVC (150X150X4mm) .15
