2  Measurment Volume | Probe Dimensions

2.1  Introduction

In theory the penetration depth of the electrical and magnetic flux lines reach indefinitely far into the  measured 

material. However, the effective penetration depth of a SONO-M1 probe relevant for the measurement is 

 approximately cm in the vicinity of the probe rods. The illustration demonstrates the effective measurement 

 volume (green waveform). The measurement field is large enough to generate adequate and reliable information 

about arepresentative volume of the measured bulk good.

2.2  Measurement Volume of the SONO-M1 Probe

The penetration depth of the electrical and magnetic flux lines in theory reach indefinitely far into the measured 

material. However, the effective penetration depth of the SONO-M1 probes relevant for the measurement is 

 approximately 2 cm in the vicinity of the probe rods.  

The illustration demonstrates the effectively registered measurement volume (green waveform).
