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 – ELECTROLYTE:

Solid polymer electrolyte with high KCl content.

• Reduces measurement interference due to diffusion potentials and improves sensor response time.
• Prolongs sensor life by slowing process ingress and fouling of reference electrode.

3 – REFERENCE ELECTRODE: Ag/Ag Cl – Silamid®

The Silamid reference electrode is constructed using a glass tube internally lined with silver and packed with silver chloride powder. A polyester fiber plug is added as an additional barrier to prevent poisoning and extend sensor life.

4 – DIAPHRAGM/JUNCTION: 2X Open Hole

The 2 open hole junctions help to minimize contamination and plugging of the reference system. This will extend the time between sensor calibration and replacement in suspended solids applications.

5 – SENSOR MATERIAL: Alpha pH glass

Alpha glass is medium-impedance, fluoride-resistant, hydrogen sensitive glass designed for use in applications requiring fast response time in media with extremely high ionic strength and/or strongly oxidizing media.
