Model Number 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 = ClickLoc connector + FluidLoc cable + protector – 00 = Agency approval not required
Installation Guide
– Tighten probe case to 21.1 N•m (187 in•lb) – Do not exceed 63.3 N•m (560 in•lb) maximum torque – Turn connector finger tight only – Maximum connector torque is 0.565 N•m – Keep cable bend radius at least 25.4 mm – Use flat target of 30.5 mm diameter or larger – Use shaft diameter of 152 mm or larger – Keep probe above -34°C to protect pressure seal
Debugging & Maintenance
– Check probe health by measuring resistance – Normal resistance: 7.2 ± 0.8 ohms (center to outer conductor) – No special tools needed for connector – FluidLoc cable prevents fluid damage – ClickLoc connector gives secure connection each time
Compatibility
– This 5m probe works only with 5m Proximitor Sensor – Do not pair with 1m or 9m Proximitor sensors – Fits standard Bently Nevada monitoring systems
Certifications & Approvals
– Agency approval option: 00 (not required for this version) – For reference – temperature schedule applies: – EPL Ga and Gc: T1 (-55°C to +232°C), T2 (-55°C to +177°C) – EPL Ga and Gc: T3 (-55°C to +120°C), T4 (-55°C to +80°C), T5 (-55°C to +40°C) – EPL Dc: T280°C, T225°C, T170°C, T130°C, T105°C, T90°C

FAQ – Frequently Asked Questions
Q1: Can I use this probe with a 9 meter Proximitor sensor?
A: No. This 5m probe requires a 5m Proximitor sensor.
Q2: Why does this version have 00 approval?
A: 00 means no agency approval needed. Choose this for non-hazardous areas.
Q3: What torque should I use for the probe case?
A: Use 21.1 N•m. Never exceed 63.3 N•m.
Q4: How do I know if my cable is damaged?
A: Measure resistance. Normal is 7.2 ± 0.8 ohms. Different values mean damage.
Q5: My site temperature is 150°C. Will this probe work?
A: Yes. The probe works up to 177°C. Keep above -34°C for seal life.
Q6: The ClickLoc connector feels loose. Is this a problem?
A: No. It only needs a light click. Do not force it tighter.
Q7: Can I bend the cable around a tight corner?
A: No. Minimum bend radius is 25.4 mm. Sharper bends break the cable.
Q8: What happens if I use a smaller shaft?
A: Readings become less accurate. Minimum shaft diameter is 152 mm.
Q9: Experience tells me to extend this cable. Can I do that?
A: No. Extending changes calibration. Order the right length instead.
Selection Guide
– Step 1: Choose total length (1m, 5m, or 9m). This model is 5m. – Step 2: Match probe length to Proximitor sensor length. – Step 3: Select thread type. This uses M16 x 1.5 metric. – Step 4: Pick unthreaded length. 000 = 0 mm is standard. – Step 5: Choose case length. 080 = 80 mm fits most. – Step 6: Decide on armor. 000 = no armor for standard use. – Step 7: Select approval option. 00 = not required for safe areas. – Pro tip: For high vibration areas, pick armored cable version. For hazardous areas, choose 05 approval option.
