Pickups and Amplifiers

Carrier-Frequency Pulse Amplifiers (VTE 04)

with single pickup, for direct mounting for all ZHM 01/1 and ZHM 01/2 in cartridge construction, as well as for the LFM

The carrier-frequency 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 corrresponds to the volume flow. Versions with Push Pull output or NAMUR output (option: open collector output npn) are available.
