A damaged rotating impeller can interrupt flow checks in water or air. This replacement snap-on head helps restore the STS probe instead of replacing the complete measuring probe, with STE 005 intended for STS 005 and STE 020 intended for STS 020.
The exchangeable head is designed for windmill-type flow measuring probes used with GMH 3300 series handheld instruments. STS 005 covers water measurements from 0.05 ... 5.00 m/s, while STS 020 covers air measurements from 0.55 ... 20.00 m/s.
Replacement is straightforward: the snap-on head is pulled off in axial direction. The design supports careful maintenance of sensitive flow probes, while preserving the correct head assignment for water or air applications.
The spare head replaces the snap-on head of compatible STS flow measuring probes when the rotating impeller is damaged.
STE 005 is assigned to the STS 005 water probe, while STE 020 is assigned to the STS 020 air probe.
The replacement head belongs to the STS windmill-type anemometer probe design used for flow measurement in water or air.
The sensor head is demounted by pulling the snap-on head in axial direction.
