Transducer output wires in grounded enclosure - to twist or not to twist?
Twisting the wires does not help against electric fields, but these are shielded by the brass case. Twisting does help against magnetic fields. But if there are only a few centimeters of transducer wires inside the case and some meters of coax cable from the case, twisting the wires would cause only a very small effect. I would suspect a benefit only if there is a strong magnetic field very close to the brass case.
