Monitored Static Transducer
This Pitot-Static Transducer was used in the Nimrod system. Also marked (in ink): E.B.L.R. Nov. 99. The title of this unit is ‘Monitored Static Transducer’ and it may indicate that this was a unit used to provide a comparison with a primary unit.
The unit contains two independent P-S Capsule Units and each aneroid capsule (or usually two capsules to magnify the movement) is coupled to an arm sliding along a wire wound resistor. A small servo motor was used to further amplify the movement of the capsules to operate the internal gear train. This simple arrangement transmits the difference signal between the Pitot and Static pressure to a remote indicator for Indicated Air Speed. The signal is also fed to a locking solenoid used in Height Lock mode to maintain barometric height.
