WebAug 27, 2024 · The Diamond Tester has become standard gemological equipment. Your basic diamond tester only tests one thing—thermal conductivity, which means it can distinguish diamonds and moissanite from other stones, like Cubic Zirconia (CZ), but it typically CAN’T tell Moissanite and Diamonds apart (it registers both as diamond). WebMar 8, 2016 · When a vehicle passes over the loop or is stopped within the loop, the vehicle induces eddy currents in the wire loops, which decrease their inductance. The decreased inductance actuates the electronics unit output relay or solid-state optically isolated output, which sends a pulse to the controller signifying the passage or presence of a vehicle. shapes vocabulary for kids
