Ensuring that emergency shutdown is performed reliably when a short circuit occurs, detection of delayed potentials, and safe signal transmission are essential not just for trouble-free railway operations but for employee and passenger safety as well. For this reason, transducers for railway applications have to meet the highest standards of reliability and precision. For Knick Elektronische Messgeräte, this has been the central focus in the development and manufacturing of highly available transducers and signal conditioners over several decades. The instrumentation manufacturer based in Berlin, Germany, has been supplying the international railway industry with products for high-voltage applications for over 40 years.

Modbus integration

Berlin – Berlin-based process analytical specialist Knick Elektronische Messgeräte (Knick) and Cincinnati-based M4 Instruments announce their mutual strategic investment in M4 Knick LLC, Cincinnati.

Measuring technology specialist Knick is introducing the ProLine P 44000 series of transmitters with extremely high isolation for use with Pt100 resistance thermometers in high-voltage motors (up to 11 kV).

Measuring technology specialist Knick's Stratos series analyzers for pH level, conductivity and dissolved oxygen measurements are widely used in the chemical industry, in process engineering, power plant technology, and the pharmaceutical and biotechnology sector due to their exceptional versatility, high reliability and full-fledged compatibility with conventional sensor types (analog, digital, Memosens). Knick now introduces Stratos series analyzers with integrated bus interfaces for PROFIBUS DP, PROFIBUS PA or FF (Foundation Fieldbus).

Measuring technology specialist Knick now offers an enhanced version of their sensor management software for Memosens technology: MemoSuite Advanced allows for the calibration of up to ten sensors at once. The intuitive-to-operate PC software enables users to easily pre-calibrate sensors for pH, ORP, oxygen, conductivity and temperature measurement under optimal conditions in the lab, i.e. completely dispenses with complicated on-site calibrations in adverse environmental conditions. Sensors can be connected to a PC via USB using the interface converter MemoLink included in supply.

Berlin – The requirements on operational and safety-related circuits in plants are continuously growing which also affects the technical requirements on components. Often, functional safety can only be increased with much effort and at the expense of availability. Proving that high safety standards and high availability can go hand in hand, Knick present ProLine P 22400 passive standard signal isolators certified for applications with a SIL3 safety integrity level according to EN 61508.
