Frequently Asked Questions (FAQ)
Why choose an 8mm probe over smaller sizes?
The 8mm body provides superior physical strength. It better resists bending and damage in tough installations.
Is this probe safe for use in explosive areas?
Yes. The model suffix -05 confirms ATEX, IECEx, and CSA approvals for hazardous locations.
How do the length options work?
The suffix defines key dimensions. For example, -43 means a 4.3-inch case length for proper fit in your mounting hole.
What is the main risk during storage?
Storing below -34°C (-30°F) can damage the internal pressure seal. Keep probes in a controlled environment.
Can humidity affect the calibration?
Minimal effect. Tests show less than 3% sensitivity change after 8 weeks in 93% humidity.
When is the FluidLoc option necessary?
Choose FluidLoc if the probe installs where machine oil could leak through the cable’s core. It seals the cable interior.
Buyer’s Selection Guide
- Confirm System Type: Ensure compatibility with 3300 XL monitors.
- Check Required Lengths: Match the -10-43-10 suffix to your mechanical fit.
- Review Environment: For very high temperatures, specify the ETR version.
- Assess Fluid Risk: Select FluidLoc cable option if oil leakage is a concern.
- Verify Certifications: For hazardous areas, the model must end with -05.
