Inductive Pulse Amplifiers (VIE 02)

with single pickup, for screwing in for all KEM flow meters

Inductive pulse amplifiers of series VIE 02 for measuring cells in aluminum housing. We advise the identical carrier-frequency pulse amplifiers VTE 02 for measuring cells in steel housing.

The inductive pickups detect the r.p.m. of KEM flow meters. Each passing of a tooth will be detected contactless and produces a pulse at the output. Therefore each pulse corresponds to a fixed volume and the frequency corresponds to the volume flow. Versions with Push Pull output or NAMUR output (option: open collector output npn) are available.

The pickup is screwed into the meter via a thread M14×1.5 (option UNF ½”-20). Accordingly the VIE 02 fit on all KEM measuring cells.
