Zusammenfassung:A pneumatic pressure probe comprises an orifice tube extending through a plastic bushing that seals a pressure chamber. The orifice tube has a passage shaped substantially like a converging/diverging de Laval nozzle to reduce turbulence in fluid flow through the probe. More laminar fluid flow reduces noise and inaccuracy in the output of the probe. Laminar flow also reduces user dependent results. The plastic bushing and a specially shaped probe tip reduce extraneous fluid leakages from the probe.
