Type NORIMETER 3 analogue indicator with stepper motor technology, universally applicable Construction type Scope of application NORIMETER 3 indicators are mainly used in the Shipbuilding industry, transport technology and mechanical engineering. The indicators fulfill the requirements of the DIN EN 50155 for railway technology and of common ship classification societies and thus, are suitable for applications in harsh environments. Thanks to the mechanical construction, the housing is highly resistant against salt spray and thus, outdoor use is possible. The DIN-compliant housing sizes are suitable for installation in control cabinets and control panels with pre-stamped standardised installation openings. Display principle The display on the NORIMETER 3 is via a high-resolution stepper motor with integrated precision transmission at a resolution of 12 steps per degree. A display with a 240° standard scale thus achieves a resolution of the measuring signal in 2880 display steps. The motor itself has a mechanical transmission end stop and an angle of rotation of 315°. This makes a scale angle of up to 300° possible. In addition, a display with a 360° rotating faceplate is available (see data sheet DB-NIQ31). The motor is controlled by the firmware via a digital filter. This results in an optimum combination of smooth adjustment of the measure value and high precision (without the pointer wavering). The transmission backlash is almost halved by the firmware. This measure allows a display accuracy greater than 0.5% to be achieved relative to the measuring range. Special features • Indicator with non-linear scales (spreading scale) available • 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 • Option: Available as indicator with 360° rotary faceplate (see datasheet DB-NIQ31) or as indicator with frequency input with integrated direction-of-rotation monitoring • Option: Minimum-Maximum value indication for saving and indicating the highest and lowest measured value • Option: Control functionality for sensor failure and power supply failure (Live-Zero) • Connection for external illumination control as well as separate default brightness setting. On devices with an illuminated pointer it is also possible to set the pointer lighting separately.

| Standard version NORIS Automation GmbH Standard version Scale and pointer The markings and the graduation of the scale are in accordance with DIN43802 and DIN43780 but can also be customer-specific on request. Coarse graduation With this graduation, defined graduation marks are thicker. This allows the values to be better read even at a higher distance. Orientation graduation With this graduation, all graduation marks are of equal width.

NORIS Automation GmbH Standard version | ATTENTION: Line compensation changes the factory setting. Incorrect line compensation can cause the reading to deviate from the actual measured values. It may then not be possible to detect when limit values are overshot or undershot. NORIS shall accept no liability for any damage which may be incurred as the result of incorrect line compensation. For indicators with PT100/PT1000-, NTC thermistor or resistance inputs, the optional function "Line Compensation" is implemented as standard. Thus, the indication can be adapted to probable existing signal...

| Optional special functions NORIS Automation GmbH Optional special functions Special functions can be integrated into NORIMETER 3 indicators upon customer request. Some functions can be combined. Note: Auxiliary functions that use the indicator's auxiliary port (AUX) cannot be combined. Note: Optional special functions are not covered by the ordering code in the type code and must be requested in the order text. Signal LED and flashing pointer Note: The functional principle required and the application (coupling) must be stated in the order and can then no longer be changed by the...
