FAQ

What is the primary benefit of the PEEK tip?
The PEEK material offers superior chemical resistance and prevents electrostatic sparking in hazardous steam turbine environments.

Can this probe replace a 7200 series sensor?
Yes, the 3300 XL series is engineered to physically and electrically replace all standard 7200 25mm/35mm systems seamlessly.

How do I troubleshoot an erratic signal?
Verify connector cleanliness and confirm the DC resistance measures 8.8 ± 1.1 Ohms. Significant deviations often signal cable degradation.

Selection Guide

Select this 3300 XL model if your operating temperature exceeds 150°C. The included stainless steel armor is mandatory for installations requiring high mechanical protection and resistance to corrosive steam environments.
