定义
The probe body or sheath is a critical component of temperature and pH probes, serving as the protective outer casing that houses the sensing elements. It provides mechanical protection, chemical resistance, and thermal insulation while allowing accurate measurement transmission. In industrial settings, it ensures sensor longevity and measurement reliability in harsh environments.
工作原理
The probe body/sheath functions as a protective barrier that isolates sensitive sensing elements from external conditions while allowing thermal or chemical interaction for accurate measurements. It maintains structural integrity and prevents contamination of the sensing surface.

常见问题

What materials are best for corrosive environments?

Hastelloy C-276, titanium, or PTFE-coated sheaths provide excellent corrosion resistance in acidic or alkaline conditions.

How does sheath material affect measurement accuracy?

Material thermal conductivity impacts response time; thinner walls and higher conductivity materials improve response but may reduce durability.

Can probe sheaths be customized for specific applications?

Yes, custom lengths, diameters, materials, and thread types are available for specialized industrial requirements.
