Wheel and Flag Indicators Electromagnetic Wheel Indicators Hypernetics has developed a family of low power, high performance indicators for use in prime flight and engine instruments. Hypernetics range of electromagnetic indicators includes digital magnetic wheel modules and flag failure indicators. Electromagnetic indicators are ideally suited as aircraft instrument readouts.
Reliability is excellent even in direct sunlight.
If power fails, readout remains visible. The only moving component is the indicator permanent magnetic rotor which is mounted on ball bearings. Damping is optimized for smooth operations. Designs ensure reliable performance in severe thermal shock environments. Other options include moving degree or decimal point, right and left hand versions, symbols or messages, different travel angles, operating voltages and currents.
