Conductivity sensor for use in aggressive media

(high fibre concentration), and in heavily soiled media, wastewater and fouling media. In summary the key features include: - Process-wetted material: PFA - Sturdy design - Resistant to contamination and fouling - Range of six decades - Inductive measuring principle, full galvanic isolation of sensor coils from process medium - Digital with Memosens protocol. The SE 656N sensor is available from Mecosa (Pty) Ltd, the sole agent for Knick Elektronische Messgeräte in Southern Africa.

The Knick SE 656N toroidal conductivity sensor is a sturdy and corrosion-resistant sensor that, due to its high chemical resistance and durability when exposed to aggressive media, is particularly suitable for applications in the chemical industry. A combination of a large sensor opening and dirt-repellent material prevents blockages and deposits in media with a high level of pollution. The inductive measuring principle enables full galvanic isolation of the measurement sensor from the medium. The sensor is an all-rounder, suitable for a multitude of applications with a measuring range covering six decades, from 0.002 mS/cm to 2 000 mS/cm. The digital version, equipped with the Memosens protocol, offers considerable process and data security, and ensures reliable data recording. The SE 656N toroidal conductivity sensor can be used for concentration measurement, particularly in highly oxidising acids and bases, and for online quality monitoring of chemical products in tanks and pipes, phase separation of product mixtures, in paper manufacturing
