NIQ31

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
Option: Motor with anti-clockwise rotation
Fulfils all conventional ship classifications

NORIMETER indicators of type NIQ31 are indicating instruments (gauges), high-resolution stepping motor indicators controlled by microprocesses. They have a 360° scale dial and the motor is without a mechanical stop. They serve to indicate the rudder position, propeller position and pitch on ships. Their compact and robust design makes them suitable for continuous use in harsh environments. They fulfil the approvals of the societies for commercial shipbuilding and the requirements expressed in DIN EN 50155 for transportation technology.
