Measuring Card R10

Measuring Card R10
for Insulation and Loop Resistance Monitoring

The measuring card R10 is used to measure insulation and loop resistance of copper cables, district heating pipes with sensing wires and fiber optic cables with a copper pair.

The measurements are executed by the permanent scanning of the 10 measurement channels to detect penetration of moisture, squeezing or damage as well as theft.

Contactors combined with defined resistors allow for further application beyond simple cable network monitoring.

Measuring range
Insulation resistance
0,01 .. 500 MΩ
Loop resistance
50 .. 20.000 Ω
Resolution0,01 .. 9,99 MΩ = 0,01 MΩ
   10 .. 99,9 MΩ = 0,10 MΩ
  100 .. 500 MΩ = 1,00 MΩ
50 .. 9.999 Ω = 1 Ω
10 .. 20 kΩ = 100 Ω
Max. measurement error10% of measured value ± 50 kΩ± 3% of measured value
Test voltage/ test current90 V DC / 100 μA
ProtectionThe measurement processes is insensible to noise voltage with frequencies f ≥ 16 Hz. Overvoltage higher than 90 V (a, b to ground) is diverted in order to protect the measuring card.
