Type NORIMETER 3 analogue indicator 360° indicator with stepper motor technology universally applicable Construction type Square type NIQ31 Stepper motor principle Housing sizes Protection class IEC 60529: Front of housing IP66, IP67 and IP68 (1 m, 24 h); rear of housing IP30 (standard, higher on request) Measured variables Analogue measurement signals (current/ voltage); frequency signals, resistive sensor signals (Pt100/Pt1000, NTC thermistor, resistance) Scale angular Housing material Glas fibre reinforced and uv stabilised plastic; upper part: PC GF10; base plate: PC GF30; face made of lumenized float glass Externally dimmable LED illumination Supply voltage 18 ... 36 VDC, other voltages on request Fire protection Display principle Special features Type NIQ31 analogue indicators are commonly used in the fields of the Shipbuilding industry, e,g, to indicate the rudder position, propeller position and pitch on ships. Signals commonly used in industry, such as analogue measuring signals, are fed in directly and shown on a customised scale with a dial that can be turned through 360°. Thanks to its mechanical design, the casing is extremely resistant to salt spray, enabling use in outdoor applications. The DIN-compliant housing sizes are suitable for installation in control cabinets and control panels with pre-stamped standardised installation openings. • Long lifetime due to compact and robust technology, a high protection class and a glass-fibre-reinforced, salt spray resistant plastic housing, suitable for outdoor areas Display principle • Option: Motor with anti-clockwise rotation • Individual scale design and corporate logos possible, even for small quantities • Monitoring for valid measuring signal • Option: Minimum-Maximum value indication for saving and indicating the highest and lowest measured value • Fulfils all conventional ship classifications A high resolution motor without a mechanical stop is used in 360° indicators to enable continuous rotation of the dial. The entire measuring range is divided into 4320 graduations. As the motor in this indicator has no mechanical stop, the zero point is found by scanning of a position marker on the underside of the dial. Gear backlash of the stepper motor is virtually eliminated by a special motor controller. This method enables pinpoint positioning accuracy of the dial in both directions. The indicator additionally corrects the gear backlash every second when the dial is stationary. The reading is corrected if it deviates from the correct value (within the gear backlash) due to impact or vibration.
