Q1: What is the primary function of the 164517-070-10-02-00?
It is a ceramic capped eddy-current proximity probe used for non-contact measurement of shaft vibration, axial position, and displacement on rotating machinery. Its ceramic tip is specifically designed for applications in aggressive chemical or high-pressure environments, such as anhydrous ammonia or other extreme pH conditions.
Q2: What makes this probe different from standard 3300 XL probes?
The key difference is the ceramic capped tip. This alumina ceramic cap prevents corrosive gases and liquids from entering the front end of the probe case, making it suitable for environments that would destroy standard probe tips. The ceramic-to-metal interface is helium leak-tested to ensure a hermetic seal.
Q3: What are the limitations of this probe?
The probe is designed for front-end exposure to corrosive environments only. It does not have a rear fitting or stainless steel tube, so the rear of the probe must not be exposed to destructive environments such as water, NH₃, NH₄OH, or hydrogen sulfide.
Q4: Which monitoring systems is this probe compatible with?
It is compatible with Bently Nevada 3300 XL monitoring systems and supports 3300 XL Proximitor Sensors and extension cables. It conforms to API Standard 670 (4th Edition).
Q5: What is the recommended minimum bend radius for the cable?
The minimum bend radius should be 25.4 mm (1.0 inch) or greater. Smaller radii can deform the dielectric, alter the characteristic impedance, and introduce measurement errors.
