SDG3000 Loop Diagnosis Set

incl. reference loop and insulation measurement device

With the SDG3000 set of devices all required measurement values of an inductive loop can be evaluated. It allows the reliable examination of existing inductive loop systems such as measuring the inductivity and testing the loop insulation. By means of the included reference loop, the pre-attenuation of the loop ground (road) can be determined. All necessary components are integrated in a robust aluminum case.

MEASUREMENT VALUES:

Loops are the detectors‘ sensors. The reliable function of the detectors largely depends on the technically correct installation and laying of the loops. When laying the loops, the three most important measurement values of the loop (with and without feeder cable) should be noted:

  • Loop resistance (in Ω)
  • Inductivity (in μH) – optimum value (80 – 300) μH
  • Isolation resistance (in Ω) – higher than100 MΩ, for new installations higher than 1 GΩ (loop only)
