Probe Body: Temperature Range -20°C to 150°C, Diameter 6-25 mm

Component Specifications

Definition

The probe body is the primary structural component of a conductivity probe, designed to house and protect the internal electrodes, wiring, and reference elements while maintaining precise dimensional stability and chemical resistance. It serves as the interface between the measured medium and the sensing elements, ensuring consistent measurement conditions and protecting sensitive components from environmental factors such as pressure, temperature fluctuations, and corrosive substances.

Working Principle

The probe body provides mechanical support and environmental isolation for the conductivity measurement system. It maintains fixed electrode spacing and orientation while preventing external interference, allowing accurate measurement of electrical conductivity through the medium by creating a controlled measurement chamber around the electrodes.

Materials

316L stainless steel (food/pharma grade), PTFE (Teflon), PEEK, glass-filled polypropylene, or ceramic alumina for high-temperature applications. Material selection depends on chemical compatibility, temperature range, and pressure requirements.

Frequently Asked Questions

What materials are best for corrosive environments?

PTFE (Teflon) or PEEK materials offer excellent chemical resistance for highly corrosive applications, while 316L stainless steel with electropolished finish is preferred for food and pharmaceutical industries.

How does probe body design affect measurement accuracy?

Precise internal dimensions maintain consistent electrode spacing and orientation, while proper sealing prevents fluid ingress that could cause measurement drift or sensor failure.
