SE 655 Conductivity Sensor Product Highlight

Toroidal Conductivity Sensor for Liquids with Suspended Solids

The SE 655 Memosens toroidal conductivity sensor is ideal for measurements in liquids with suspended solids and high conductivities. This corrosion-resistant sensor is constructed of PEEK in a smooth, easy-to-clean design and comes with an integrated 3m cable. The SE 655 is highly accurate and has a low risk of contamination because of a large sensor opening.

The robust sensor design and construction, along with the integration of Memosens technology, provide for enhanced performance and a significant reduction in maintenance.

The SE 655 is suitable for use with any M4 Knick transmitter and the Portavo 908 Multi portable meter.

SE 555 pH Conductivity Sensor Anatomy

1 – SENSOR HEAD: Memosens Digital Sensing Technology

Memosens sensors provide several benefits with regard to ease of use and reduction of operating costs:

  • Submersible inductive connection removes measurement influence from moisture and humidity that are commonly present in process applications.
  • Galvanically isolated so there is no measurement influence from noise or ground loops. This is especially beneficial when using plastic holders.
  • Calibration and diagnostics can be performed in the shop or lab. This reduces field maintenance time and process downtime.

2 – SENSOR MATERIAL:  PEEK

PEEK has excellent mechanical and chemical resistance properties that are retained under high temperatures. It is highly resistant to thermal degradation, as well as attacks in both organic and aqueous environments.

3 – SENSOR MOUNTING: Threaded Lock-Nut

The threaded connection enables easy mounting into an immersion style holder.  The lock-nut configuration allows for connection to a variety of flange materials and sizes.

4 – SENSING ELEMENT:  Inductive/ Toroidal Conductivity

The electrodeless design prevents any measurement effects due to polarization. The sensing element delivers repeatable, accurate measurements even in highly polluted liquids with a tendency to form buildup.
