Signal Conditioning

Powerful isolating amplifiers

Considering the increase of automation, isolating amplifiers are required which convert, isolate, monitor, protect and visualise your digital and analogue signal values from industrial and process automation, e.g. temperature, pressure, level, flow volumes, weight, and speed.
Weidmüller’s signal converters for DC standard signals, 4-20 m A and 0-10 V isolating amplifiers, switching amplifiers, frequency converters, and threshold switches are characterised by a high level of accuracy, universality and a wide assortment of variants.
