The 330701-00-40-10-11-05 belongs to the Bently Nevada 3300 XL series of 11 mm proximity probes. This sensor measures shaft vibration, radial position, and axial displacement on rotating machinery. Moreover, its non-contact eddy current design suits steam turbines, compressors, and large motors. The probe uses a polyphenylene sulfide (PPS) tip and an AISI 304 stainless steel case. Additionally, the FluidLoc cable resists fluid ingress in wet or oily plant conditions. Each unit ships with a miniature coaxial ClickLoc connector and a connector protector. The 1.0 metre total length fits tight mounting spaces near the bearing housing.
The 330701-00-40-10-11-05 combines a compact probe body with a flexible triaxial cable. Specifically, the probe dc resistance from the center conductor to the outer conductor is 5.9 ± 0.5 ohms at 1.0 metre. The cable is 75 Ω triaxial with fluoroethylene propylene (FEP) insulation. Furthermore, the probe tip material is polyphenylene sulfide (PPS), and the case material is AISI 304 stainless steel (SST). The connector type is a Miniature coaxial ClickLoc connector with a connector protector and FluidLoc cable. In addition, the agency approval option is Multiple Approvals.
Key ordering options break down as follows:
330701 = 3300 XL 11 mm probe, 1/2-20 UNF thread, without armor
Unthreaded length option 00 = 0.0 in
Overall case length option 40 = 4.0 in
Total length option 10 = 1.0 metre (3.3 feet)
Connector and cable option 11 = Miniature coaxial ClickLoc connector with protector, FluidLoc cable
Agency approval option 05 = Multiple Approvals
The probe case thread is 1/2-20 UNF. The maximum length of thread engagement is 0.750 in. For probe case torque on 1/2-20 and 5/8-18 cases, the maximum rated value is 45.2 N·m (400 in·lb), while the recommended value is 15.2 N·m (133 in·lb). The connector-to-connector torque is finger tight, with a maximum of 0.565 N·m (5 in·lb). Meanwhile, the minimum bend radius is 25.4 mm (1.0 in), with or without SST armor.
The operating and storage temperature range is -51°C to +177°C (-60°F to +351°F). However, exposing the probe to temperatures below -34°C (30°F) may cause premature failure of the pressure seal. The probe seals differential pressure between the tip and case with a Viton O-ring. Note that probes are not pressure tested before shipment. For EPL Ga and Gc classifications, the ambient temperature range for the probe alone reaches -55°C to +232°C at T1, -55°C to +177°C at T2, and -55°C to +120°C at T3.
First, verify the probe thread matches the mounting hole, since the 330701-00-40-10-11-05 uses a 1/2-20 UNF thread. Next, apply the recommended case torque of 15.2 N·m (133 in·lb) and never exceed the 45.2 N·m (400 in·lb) maximum. Then, route the FluidLoc cable with a minimum bend radius of 25.4 mm (1.0 in) to avoid conductor damage. Besides, keep the ClickLoc connector finger tight and do not exceed 0.565 N·m (5 in·lb). Finally, confirm target clearance and gap voltage during commissioning, and protect the probe tip from mechanical impact.
