Separators and signal converters from the German brand Knick are synonymous with reliability, precision and top-class industrial engineering. For decades, they have been an indispensable part of automation, power engineering, process industry and railway installations.

ELTRON has been the exclusive and official representative of Knick in Poland for many years. We offer a full range of separators and transducers from this brand, professional technical advice and fast stock availability.

Why choose Knick isolators?

KNICK signal isolators and transducers provide:

• galvanic isolation between input and output (up to 10 kV)
• elimination of ground loops and EMC interference
• precise processing of analogue signals (mA/V)
• universal inputs for thermocouples, Pt100, current and voltage signals
• compact DIN housings, low energy consumption, high measurement stability
