Kistler 5805 3-Channel Galvo Amplifier with 3x Kiag Swiss 5211A 110V

Kistler 5805 3-Channel Galvo Amplifier with 3x Kiag Swiss 5211A 110V

The Kistler 5805 is a benchtop 3-channel galvo amplifier housing three Kiag Swiss Type 5211A galvanometer amplifier modules. Galvo amplifiers of this type are used to drive galvanometer elements in analog strip chart recorders, converting low-level electrical signals into precisely controlled deflection currents for high-fidelity waveform recording. Manufactured by Kistler Instrumente AG of Winterthur, Switzerland, the 5805 mainframe provides power distribution and rear-panel signal routing for all three channels in a single compact enclosure.

Applications

Galvo amplifiers like the Kistler 5211A are designed to drive the galvanometer movements inside analog chart recorders — instruments that were a standard tool in scientific, industrial, and engineering data acquisition from the 1960s through the 1980s. By converting a voltage or current input into a precisely scaled deflection current, the amplifier allows the recorder pen or light beam to trace accurate waveforms on moving paper or film. Multi-channel units like the 5805 allow simultaneous recording of several independent signals — common in applications such as vibration and shock measurement, piezoelectric transducer signal conditioning, materials testing, biomechanical research, and electrophysiology. Kistler Instrumente AG is a Swiss precision instrumentation company with a long history in piezoelectric sensing and charge amplification; the 5211A module complements that ecosystem. While modern data acquisition systems have largely replaced analog galvo recorders in new installations, these amplifiers remain sought after for maintaining legacy recorder systems, for vintage instrumentation collections, and for applications where true analog chart recording is still preferred. The 5805 dates from the era of classic Swiss analog measurement instrumentation, consistent with Kistler's product lines of the 1970s and early 1980s.
