Type NORIMETER 3 analogue indicator 360° indicator with stepper motor technology universally applicable Construction type Scope of application 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. Display principle 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. Special features • 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 • 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 • Option: Motor with anti-clockwise rotation Datasheet DB-NIQ31-EN | V01.04 | 25/02/2019 | Valid from product revision A | www.noris-group.com | sales@noris-group.com

NORIS Automation GmbH Standard version | Monitoring functions Integrated measuring signal monitoring detects: • Total sensor failure / invalid sensor signals • Broken wire in the sensor cable • Short circuit in the sensor cable The error is shown by: • The light at maximum brightness slowly flashing There are further possible monitoring functions for 360° indicators without positioning optimisation (depending on the measured variable): Changing the direction of rotation With this function, you can manually change the direction of rotation of the dial with the push button on the rear side of...

| Optional special functions NORIS Automation GmbH Min/max display Indicators with this optional auxiliary function register fluctuations of the measuring signal and save the highest and the lowest measured value in the internal measured-value memory. Critical measured values that, for example, occur during the absence of monitoring personnel can therefore be recalled later on. By means of a signal at the indicator's auxiliary port (e.g. via an external button), the saved values can be displayed or deleted. Note: The min/max data is not permanently saved and is lost when the indicator is...
