This panel meter is designed to provide an accurate, zero adjusted indication of a 4 to 20mA loop current. Calibration is via two multi-turn potentiometers that allow sensitive adjustment over a wide range. A low drift bandgap reference circuit ensures accurate reading over a wide temperature range. LED backlighting is provided that is powered from the current loop, providing a clear display, even under low light conditions. The unit is supplied with a plastic mounting bezel and there is an additional bezel available (87-6380) that will provide a waterproof seal to IP67. |
