SE656 Toroidal Conductivity Sensor | Memosens | Fixed cable | Ex | PFA | Resistant to highly oxidizing media

Description

SE656 Toroidal Conductivity Sensor | Memosens | Fixed cable | Ex | PFA | Resistant to highly oxidizing media

Universal and precise conductivity sensor with maximum chemical resistance to highly oxidizing media. Digital with Memosens protocol.

  • 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
  • Also for hazardous areas

The SE656X digital toroidal conductivity sensor is a sturdy and corrosion-resistant sensor that, thanks 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 pollution degree. The inductive measuring principle enables full galvanic isolation of the measurement from the medium. 

The sensor is an all-rounder, suitable for a multitude of applications with a range covering six decades. Equipped with Memosens protocol as a digital version, it offers considerable process and data security, and ensures reliable data recording. Also for hazardous areas.

Applications
Concentration measurement, in particular of highly oxidizing acids and bases, online quality monitoring of chemical products in tanks and pipes, phase separation of product mixtures, paper manufacturing (high fiber concentration), heavily soiled media and wastewater, fouling media.
