Identify every exposed material
The sensing tip, process body, seal and adapter may use different materials. A specification saying “stainless steel sensor” can leave the tip and seal undefined. Request a wetted-parts list and confirm any optional material against the actual order code.
The supplied Lisen manual mentions PEEK with 316L or user-specified titanium. That does not establish that every pictured sample contains the optional metal.
Chemical compatibility is process dependent
Concentration, temperature, contaminants and exposure time can change corrosion or polymer behavior. Abrasive particles add another mechanism of deterioration. Use qualified material guidance and the supplier’s confirmation for the actual duty rather than an unqualified claim that a material is acid-proof.
Keep evidence at the right level
A material test report can support the identity or quality of a documented batch. It does not alone certify the complete sensor for food contact, hazardous areas or a safety function. Request the appropriate product-level evidence and traceability when those requirements apply.
What to confirm for your application
- All wetted parts and seal materials
- Actual chemicals and concentrations
- Cleaning conditions and exposure time
- Abrasion and corrosion mechanisms
- Batch and product-level documentation
