FAQs

Q1: What is the primary function of the 330105-02-12-05-02-00?
It is a reverse-mount eddy-current proximity probe used for non-contact measurement of shaft vibration, axial position, and Keyphasor reference on rotating machinery. It outputs a voltage proportional to the gap between the probe tip and the conductive shaft surface .
Q2: What makes "reverse mount" different from standard probes?
A reverse-mount probe is installed from behind the mounting surface, with the cable exiting in the opposite direction. This design is ideal for compact machinery layouts or locations with limited frontal access where standard forward-mount probes cannot fit .
Q3: What are the key specifications for this probe?
-
Cable length: 0.5 meter
-
Scale factor: 7.87 V/mm (200 mV/mil)
-
Linear range: 2.0 mm (80 mils)
-
Operating temperature: -51°C to +177°C
-
Thread: 3/8-24 UNF
Q4: How do I ensure proper system compatibility?
The total electrical length of the probe cable plus extension cable must equal the Proximitor sensor's rated system length. Since this probe has a 0.5m cable, you must pair it with a 0.5m Proximitor (or use an extension cable to match a longer system) . All 3300 XL components are fully interchangeable without bench calibration.
Q5: What are the typical applications for this probe?
Common applications include steam turbines, gas turbines, centrifugal compressors, pumps, and motors where space constraints require reverse-mount installation. It is widely used in power generation, oil & gas, petrochemical, and heavy manufacturing industries for machinery protection and predictive maintenance.
