EFP-07-Technical-Data

Frequency range

DC .... 50 kHz

 

 

Contact resistance

50 – 500 Ω (for normal soils)

 

 

Effective surface

2 cm2

 

 

DC potential

0.1 to 0.9 mV

 

 

Temperature Range

 

+5 to +40 °C

 

 

Temperature Drift

n μV/°C

the temperature drift of two electrodes in the current circle is much lower than n μV/°C because of the same electrical behaviour;

electrodes can be used at a wider outside temperature range if buried deep enough

4-5 years; careful usage

 

 

External dimensions
