Same steps as the real rod-depth tool: calculate → field measurement → delivery report. Dummy data for five cities — see if it pays off for your installs.
This is dummy data — not a real measurement
Locations, depths, Ra values and GPS are fictional. No live BRO call, no database write, no credit use. For product preview only.
City
Location & soil data
Damrak 1, 1012 AB Amsterdam
Kleibodem · relatief lage ρ · ρ ≈ 28 Ω·m · GHG 1.4 m
Demo location — in production EarthGND fetches BRO soil data from the postcode.
Soil profile (demo BRO)
| Diepte | Klasse | ρ (Ω·m) |
|---|---|---|
| −1 m | klei | 35 |
| −3 m | klei | 28 |
| −6 m | klei | 22 |
| −10 m | klei | 20 |
Klasse I — Laag risico
Zeer geleidende klei — aarding meestal eenvoudig haalbaar.
Electrode & parameters (demo)
Electrode: Verticale pen
Drijfmethode: SDS-breekhamer
Diameter: Standaard grondpen (5/8″) — 14 mm
Target resistance: Overig · utiliteit ≤ 1,8 Ω
ρ effectief: 28 Ω·m
GHG: 1.4 m
Required rod depth (average)
Recommended configuration
1 pen — 4.80 m diep
Predicted Ra: 1.42 Ω
Typisch: snellere diepte-inschatting + opleverdossier zonder handmatige tabellen.
Gunstig
GWT 1.0m — natte periode
Ra ≈ 1.28 Ω
Gemiddeld
GWT 1.4m — gemiddeld
Ra ≈ 1.42 Ω
Ongunstig
GWT 2.6m — droge zomer
Ra ≈ 1.63 Ω
Resistance vs. depth (demo)
Drag the marker — same chart as the real rod-depth calculator. See which Ra belongs to each depth on this demo profile.
Weerstand vs. diepte — sleep om te verkennen
Bij 4.8 m is R ≈ 6 Ω — hoger dan het doel van 1.8 Ω
