Type NORIMETER 3 analogue indicator with stepper motor technology, universally applicable Construction type Round type NIR3; square type NIQ3 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 (Voltage, current), Frequency signals, Resistive sensor signals (Pt100/Pt1000, NTC thermistor, resistance) Scale angular With pointer up to max. 300° (standard 240°) Housing material Glas fibre reinforced, salt spray resistant 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 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. • 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 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). • 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. 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.
