Installation & Troubleshooting FAQ
Q1: What is the recommended installation gap setting and initial output voltage for this 11mm system?
A: The recommended initial physical gap setting for the 3300 XL 11mm probe system is 2.5 mm (100 mils) relative to the target face. At this position, which represents the midpoint of its extended 4.0 mm linear range, the Proximitor sensor output should read approximately -9.0 Vdc or -10.0 Vdc depending on the target configuration. Adjust the mounting threads slowly until the multimeter matches this calibration value before securing the outer nut.
Q2: What is the maximum torque value for the 5/8-18 UNF case of this 330707 probe?
A: The recommended structural installation torque is 15.2 N·m (133 in·lb), and you must never exceed the maximum rated limit of 45.2 N·m (400 in·lb). Applying excessive force when threading the probe into a casing or mounting bracket can bind the internal threads or fracture the high-performance polyphenylene sulfide (PPS) TipLoc molded sensor face.
Q3: Can I use silicone tape around the ClickLoc connection area inside the turbine casing?
A: No, wrapping the probe-to-extension cable link with self-fusing silicone tape is strictly prohibited inside the main machine housing where it comes into contact with hot turbine oil. Industrial oils degrade the tape compound quickly, causing electrical contamination. You must instead rely on the built-in fluorosilicone connector protector that comes standard with this specific 11 cable option.
