Inductive Pickups and Amplifiers (IF and VIEG)

for extreme medium temperatures

Inductive pulse amplifier of serie IF are particularly suitable for measuring cells in aluminum housing and applications with high temperature (-196 °C up to +350 °C [320.8 °F up to +662 °F]). For all other applications we recommend the carrier frequency transducers of the VTE series.

The inductive pulse amplifier 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.

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