Hierarchical Suffix Breakdown
– 330709 = 3300 XL 11 mm Probe, M16x1.5 thread, no armor – 000 = Unthreaded length 0 mm – 080 = Overall case length 80 mm – 50 = Total length 5.0 meters – 11 = Mini coaxial ClickLoc connector + FluidLoc cable – 05 = Multiple agency approvals
Installation Guidelines
– Use recommended torque 21.1 N•m (187 in•lb) for probe case – Do not exceed maximum torque 63.3 N•m (560 in•lb) – Tighten connector finger tight only – Maximum connector torque is 0.565 N•m (5 in•lb) – Keep minimum bend radius of 25.4 mm (1.0 inch) – Minimum target flat surface diameter: 30.5 mm (1.2 in) – Minimum shaft diameter: 152 mm (6.0 in) – Avoid exposing probe below -34°C (30°F) to protect pressure seal
Debugging & Maintenance Convenience
– Easy resistance check: measure center to outer conductor – Expected probe resistance: 7.2 ± 0.8 ohms (for 5m length) – No special tools needed for connector tightening – FluidLoc cable resists oil and fluid ingress – ClickLoc connector provides secure, repeatable connection
Compatibility Note
– This 5 meter probe works only with the 5 meter Proximitor Sensor – Do not use with 1m or 9m Proximitor sensors – Compatible with standard Bently Nevada monitoring systems
Certifications
– Multiple approvals (option 05) – EPL Ga and Gc temperature classifications: T1 to T5 (-55°C to +232°C range) – EPL Dc classifications: T280°C to T90°C – Temperature class depends on ambient temperature range

FAQ – Frequently Asked Questions
Q1: Can I use this probe with a 9 meter Proximitor sensor?
A: No. This 5 meter probe works only with the 5 meter Proximitor sensor.
Q2: What happens if I over-torque the connector?
A: Over-torque above 0.565 N•m may damage the connector. Keep it finger tight.
Q3: Why does the probe fail below -34°C?
A: The pressure seal may crack. Keep temperature above -34°C for seal reliability.
Q4: How do I check if my probe is damaged?
A: Measure resistance from center to outer conductor. Normal value is 7.2 ± 0.8 ohms.
Q5: Can I bend the probe cable sharply?
A: No. Minimum bend radius is 25.4 mm. Sharper bends damage the cable.
Q6: What target size do I need for accurate readings?
A: Use a flat target at least 30.5 mm wide or a 152 mm diameter shaft.
Q7: My site is very hot. Which temperature class applies?
A: Check your ambient temperature. For +120°C use T3 class (EPL Ga). For +177°C use T2.
Q8: Experience says the ClickLoc connector feels loose. Is that normal?
A: Yes. A slight click feel without resistance is normal. Do not force it.
Q9: Can I extend the cable myself?
A: No. Extending changes resistance and calibration. Order the correct length instead.
Selection Guide – How to Choose the Right Probe
– Step 1: Measure your required total probe length. Options are 1, 5, or 9 meters. – Step 2: Check your thread type. This model uses M16 x 1.5 (metric). – Step 3: Confirm your Proximitor sensor length. Must match probe length. – Step 4: Select unthreaded length (000 = 0 mm is standard). – Step 5: Choose overall case length (080 = 80 mm for most applications). – Step 6: Pick armor option (000 = no armor for standard use). – Step 7: Verify temperature range matches your environment. – Pro tip: For high vibration areas, consider armored cable (not this model). For chemical exposure, FEP cable works best.
