Frequently Asked Questions (FAQ)

What is the main advantage of a PROXPAC kit over buying parts separately?

• The PROXPAC XL kit provides a pre-engineered, matched system. It ensures compatibility between the probe, housing, and standoff dimensions, eliminates sourcing multiple parts, and includes all necessary seals and hardware for a secure, environmentally protected installation.

What does "B Dimension" and "C Dimension" refer to?

• These are critical mechanical dimensions. The B Dimension (40mm) is the standoff distance from the mounting surface. The C Dimension (138mm) is how far the probe tip extends from the housing, determining its final position relative to the target.

Does the housing require a separate grounding connection?

• Yes, the kit includes a stainless steel grounding liner and plate. Proper grounding of the housing is essential for electrical safety and optimal signal shielding, especially in hazardous areas.

Can I use this kit in a hazardous (classified) location?

• This specific configuration (16) includes a probe without agency approvals. For hazardous areas, you must order a PROXPAC kit with an approved probe option (e.g., code '05' for CSA/ATEX). Always verify the approval code matches your area classification.

How is the probe protected inside the housing?

• The probe is mounted within a stainless steel sleeve. The extra soft cellular silicone vibration isolation material cushions it, protecting the sensitive measurement from external vibrations transmitted through the housing and mounting structure.
