Component Specifications

Definition
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.
Working Principle
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.
Materials
Stainless steel (316L, 304), Hastelloy, titanium, PTFE, PEEK, ceramic, glass. Material selection depends on chemical compatibility, temperature range, and pressure requirements.
Technical Parameters
  • Length 50mm to 1000mm
  • Diameter 3mm to 25mm
  • IP Rating IP67/IP68
  • Thread Type G1/2, NPT, M12, M20
  • Pressure Rating Up to 100 bar
  • Insertion Length Standardized based on application
  • Temperature Range -50°C to 400°C
Standards
ISO 9001, DIN 43760, IEC 60751, ASTM E1137
