Design and Construction
This probe features an 8 mm tip, which balances sensitivity with generous clearance. Additionally, the 304 stainless steel body resists corrosion and mechanical stress. The PPS tip handles high temperatures without degrading signal quality. Moreover, the integral coaxial cable simplifies wiring and reduces connection points.
Compatibility and Installation
This sensor pairs with 3300 XL extension cables and 3300 series transducers. During mounting, technicians should maintain proper target distance, because incorrect gaps distort readings. Furthermore, the probe threads into standard mounting brackets with ease. The 1.2-meter length fits many bearing housing configurations.
Key Benefits
Industrial plants choose this probe for its stable sensitivity and rugged construction. As a result, it delivers reliable vibration data across extreme conditions. This model also meets API 670 requirements for machinery protection. Ultimately, its accurate measurements support predictive maintenance programs.
