Umrechnung der Leitergröße (AWG/SWG in mm)

Bei Kabelleiterlitzen ist die Maßeinheit mm, aber der Querschnittsbereich oder die Leitergröße wird in Quadratmillimeter (mm²), AWG (amerikanischer Drahtdurchmesser) und SWG (Standard-Drahtdurchmesser) angegeben.

Die Umrechnung von SWG/AWG in mm und mm2 ist anhand der angegebenen Tabelle leicht verständlich.

SWG = (BRITISCHER) STANDARDDRAHTSTÄRKE
B & S = BROWN UND SHARPE
AWG = Amerikanischer Drahtquerschnitt

CSA (in mm2) = [0,785 x (D)^2 ] x Anzahl der Litzen

Beispiel 1

Bei der Größe 20 AWG beträgt der CSA 20 AWG = 0,81 mm
Anzahl der Stränge = 1
CSA = 0,785 x 0,81 x 0,81 x 1 = 0,51 mm²

Beispiel 2

Für 3 x 22 SWG ist die CSA-Größe die Anzahl der Stränge = 3
Größe jedes Strangs = 22 SWG 22 SWG = 0,71 mm
CSA = 0,785 x 0,71 x 0,71 x 3 = 1,19 mm²

Die am häufigsten verwendeten Leitergrößen im AWG-Stil sind 26, 24, 22, 20, 18 und 16. Diese können eindrähtig oder mehrdrähtig sein.

Im SWG-Stil: 3 x 22 SWG, 1 x 22 SWG, 1 x 30 SWG, 1 x 24 SWG

Single Color vs Two Color Pyrometers: Which One Actually Works for Your Process?

If you’re selecting a pyrometer based only on temperature range, you could be solving the wrong problem. In practice, measurement errors are often caused by changing emissivity, dust, smoke, moving targets, or partially blocked sight paths rather than the instrument itself. That’s why the debate between single-color and two-color pyrometers continues across industries such as […]

Pyrometer vs. Thermocouple: Which is Best for Temperature Measurement?

Precision in temperature measurement plays an integral role in the efficiency, quality, and safety of many industrial processes. The decision between the pyrometer vs thermocouple is not a question of declaring one technology “better” than the other; rather, it is a question of being able to identify which measurement principle will yield optimal results for […]

SmarTrack Data Logger: How Our Thermal Profiling System Has Evolved

If you’ve been profiling furnaces, ovens or heat-treatment lines with a SmarTrack data logger for a while, you already know why thermal profiling matters — you can’t control what you can’t measure inside a closed, hot process. What’s changed recently is how well the logger measures it. After several rounds of field feedback and product […]
