INDUSTRY COMPONENT

Sensor Housing

Protective housing for pH/conductivity sensors in industrial applications

Component Specifications

Definition
A precision-engineered enclosure designed to protect sensitive pH and conductivity sensor elements from environmental factors while maintaining measurement accuracy. It provides mechanical protection, chemical resistance, and proper mounting interfaces for industrial process monitoring applications.
Working Principle
The housing creates a controlled environment around the sensor electrodes, shielding them from physical damage, temperature fluctuations, and chemical exposure while allowing proper electrolyte contact through designated openings. It maintains consistent measurement conditions and prevents contamination of the sensing elements.
Materials
316L stainless steel, PTFE (Teflon), PEEK, or PVDF depending on chemical resistance requirements. Typically features IP67 or IP68 ingress protection rating.
