Galvanic Isolation up to 6.6 kV

In industrial applications, measuring and control signals must be isolated when being transmitted – for safety reasons and in order to achieve optimal signal quality. The products used must safely master dangerously high voltage levels, a variety of groundpotentials and high common-mode voltages.

Knick's transducers and signal converters galvanically isolate the 3-ports of the input, output, and power supply from each other as standard for up to 6.6 kV of continuous isolation. The 3-port isolation reliably protects against measurement errors caused by grounding problems and interference voltage transmissions.

Accuracy

Intelligent circuit design and integrated safety margins between the normal load and the possible maximum load in the event of an error are basic design principles employed by Knick. They also include the use of high-quality parts and eliminating components with high failure rates. Knick signal conditioners are designed not only to operate reliably under normal conditions, but also to perform their function safely under extreme operating conditions. The advantages can be found in every detail.
