Engineering selection checklist
| Measurement duty | Normal, minimum and maximum value; control, monitoring or compliance objective |
|---|---|
| Process conditions | Medium chemistry, conductivity, temperature, pressure, solids and coating tendency |
| Installation | Inline, flow-through or immersion assembly; connection, insertion length and maintenance access |
| Electrical interface | Loop power, 4–20 mA scaling, HART host compatibility, cable and hazardous-area needs |
| Order validation | Confirm sensor version, materials, approvals, assembly and accessories in the current KROHNE documents |
Industry application guidance
This model can support fermentation, beverage, dairy and pharmaceutical pH loops when paired with a suitable hygienic assembly. Confirm the complete assembly, elastomers, cleanability, sterilisation profile and exact certificates required for the ordered configuration rather than inferring compliance from the family description.
