Model Number Decoder
330706-005-046-90-00-05 └─ 05 = Multiple Approvals └─ 00 = Mini ClickLoc connector └─ 90 = 9.0 meters total length └─ 046 = Reverse mount, M10x1 thread └─ 005 = Special configuration └─330706 = 3300 XL Reverse Mount Probe
Installation Guide
– Use recommended torque: 7.5 N•m (66 in•lb) – Do not exceed maximum torque of 22.6 N•m (200 in•lb) – Tighten connector finger tight only – Maximum connector torque is 0.565 N•m (5 in•lb) – Keep bend radius at least 25.4 mm – Mount from behind the target surface – Keep probe temperature above -34°C for seal life
Pressure Seal Information
– The probe seals differential pressure between tip and case – Sealing material: Viton O-ring – Probes ship without pressure testing – Contact custom design department for pressure seal testing
Compatibility
– This 9m probe works only with 9m Proximitor sensor – Do not use with 1m or 5m Proximitor sensors – Fits standard Bently Nevada monitoring systems
Debugging & Maintenance
– Check probe health with resistance test – Normal reading: 5.9 ± 0.5 ohms (center to outer conductor) – Out of range values mean cable damage – ClickLoc connector gives reliable connection every time – FEP cable resists oil and chemical damage

FAQ – Frequently Asked Questions
Q1: What makes a reverse mount probe different from standard probes?
A: Reverse mount probes install from behind the target. Standard probes mount from the front. This saves space.
Q2: My 9m probe shows 6.5 ohms resistance. Is this normal?
A: No. Normal range is 5.4 to 6.4 ohms. 6.5 ohms is slightly high. Check for cable damage.
Q3: Can I use this probe without pressure testing?
A: Yes for most applications. Only order pressure testing for high pressure environments like compressors.
Q4: What torque works best from your experience?
A: 7.5 N•m works well for most. Higher torque up to 22.6 N•m may strip threads. Start low and increase if needed.
Q5: How do I select between 1m, 5m, or 9m probes?
A: Measure distance from probe to monitor. Add 1 meter for routing. Match exactly to your Proximitor sensor length.
Q6: Does the 12 month warranty cover cable damage?
A: Warranty covers factory defects only. Cable damage from bending or crushing is not covered.
Q7: Which shipping method is fastest?
A: DHL Express is fastest for international. FedEx Priority and UPS Worldwide also offer quick delivery.
Q8: Can I extend the 9m cable myself?
A: No. Extending changes resistance and calibration. Order correct length from factory.
Selection Guide
– Step 1: Confirm you need reverse mount (tight space access from behind) – Step 2: Select total length: 1m, 5m, or 9m. This model is 9m. – Step 3: Match probe length to your Proximitor sensor length – Step 4: Check thread type. This uses M10 x 1 metric – Step 5: Choose approval option. 05 = multiple approvals for hazardous areas – Step 6: Verify temperature range meets your site conditions – Pro tip: Order spare probes to reduce downtime. Keep one in stock for emergencies.
