Bently Nevada 330701 11 mm Proximity Probe
Product Introduction
This probe belongs to the trusted 3300 XL series. It delivers reliable non-contact measurement for fluid film bearing machines. The 330701-00-26-10-11-CN variant features a short 1-meter FluidLoc cable and a miniature ClickLoc connector. Specifically, the 11 mm tip provides a longer linear range than standard 8 mm probes. Therefore, it suits applications where space is limited but measurement reach matters, such as small pumps or compact compressors.
Technical Specifications
The probe tip uses polyphenylene sulfide (PPS). Meanwhile, the case is built from AISI 304 stainless steel for durability. The cable is a 75 Ω triaxial, FEP-insulated design with FluidLoc protection. For the 1-meter length, the probe DC resistance measures 5.9 Ω ± 0.5 Ω. This model features a 1/2-20 UNF thread without armor. The unthreaded length is 0.0 inches, and the overall case length is 2.6 inches. The connector is a miniature coaxial ClickLoc type with a protector.
Mechanical and Environmental Parameters
The operating temperature range spans -51°C to +177°C (-60°F to +351°F). However, avoid exposing the probe to temperatures below -34°C. Such conditions may cause premature failure of the Viton O-ring pressure seal. The maximum thread engagement length is 0.750 inches. For installation, apply a recommended torque of 15.2 N·m (133 in·lb). The maximum rated torque is 45.2 N·m. Additionally, the minimum bend radius for the cable is 25.4 mm (1.0 inch).
Installation Guide
First, verify the thread condition and clean the mounting area. Next, route the 1-meter cable while respecting the minimum bend radius. Then, thread the probe into the mounting fixture. Specifically, tighten the probe case to the recommended torque of 15.2 N·m. Hand-tighten the ClickLoc connector only; the maximum torque is 0.565 N·m. Finally, connect the cable to the appropriate Proximitor sensor and verify the system output.

FAQ
Q1: What is the total cable length of this probe?
A: The 330701-00-26-10-11-CN includes a 1.0-meter (3.3 feet) FluidLoc cable.
Q2: What is the difference between FluidLoc and standard cable?
A: FluidLoc cable includes an additional protective layer. This layer prevents oil and fluid ingress into the cable assembly.
Q3: What is the recommended mounting torque?
A: The recommended torque for the probe case is 15.2 N·m (133 in·lb). Do not exceed the maximum rating of 45.2 N·m.
Q4: Does this model come with armor?
A: No, this specific variant is the non-armored version with a 1/2-20 UNF thread.
Q5: How will this item be shipped?
A: We ship worldwide via Fedex, UPS, and DHL.
