| Sensor model naming rules: the first letter marks narrowband G or wideband W. The middle number is the center frequency KHz, after the number/marks the subdivision model, and the specific difference is indicated in the remarks column. Other female definitions: built-in front amplifier (I), high temperature (H), intrinsically safe explosion-proof (S), differential (D), miniature (M). |
