Technical Specifications of Bently Nevada 330881-00-04-150-06-02

Measurement & Performance Data

The Bently Nevada 330881-00-04-150-06-02 housing assembly accepts a separate 3300 XL 8mm probe. Once you install a probe, the system delivers a linear range of 2 mm (80 mils). This range starts at 0.25 mm from the target. The incremental scale factor (ISF) measures 7.87 V/mm ±5%. Its frequency response spans 0 to 10 kHz with -3 dB. Minimum target size for this system is 15.2 mm diameter.

Environmental Limits & Protection

The housing operates with probe tip temperatures from -51°C to +177°C. Exposure below -34°C may damage the pressure seal. The housing holds an IP66 rating verified by BASEEFA. It survives two separate 4 Joule impacts at -39°C and 115°C. CSA also confirmed a 7 Joule impact at room temperature.

Temperature Classification Schedule

This PROXPAC XL housing includes specific temperature ratings for different EPL levels. For EPL Ga and Gc, the ratings are T1 (-55°C to +232°C), T2 (-55°C to +177°C), T3 (-55°C to +120°C), T4 (-55°C to +80°C), and T5 (-55°C to +40°C). For EPL Dc, the ratings are T280°C at Ta -55°C to +232°C, T225°C at Ta -55°C to +177°C, T170°C at Ta -55°C to +120°C, T130°C at Ta -55°C to +80°C, T105°C at Ta -55°C to +100°C, and T90°C at Ta -55°C to +40°C.

Electrical Specifications

This model needs -17.5 Vdc to -26 Vdc power without barriers. With barriers, use -23 Vdc to -26 Vdc. Power supply sensitivity stays under 2 mV change per volt change. Output resistance is 50 Ω. Field wiring uses 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor triax cable.

Mechanical Construction & Materials

The probe case uses AISI 304 stainless steel. Probe tip material is Polyphenylene Sulfide (PPS). Housing uses UV-resistant, glass-reinforced PPS with conductive fibers. Recommended torque for the retaining nut is 29.5 N·m.

Dimensions & Configuration Notes

The standoff adapter (B Dimension) equals 40 mm. The probe penetration (C Dimension) equals 150 mm. Probe and approvals option 00 means this unit comes with no probe and no formal approvals. You must purchase a compatible 3300 XL 8mm probe separately. This version includes one 3/4-14 NPT fitting, one 3/4-14 NPT to 1/2-14 NPT SST reducer, and two plugs. Mounting thread is 3/4-14 NPT.

Installation Guide for PROXPAC XL Housing Assembly

Follow these steps to install the Bently Nevada 330881-00-04-150-06-02 correctly.

• Purchase a Probe Separately: This unit does not include a probe. Order a 3300 XL 8mm probe with your required approvals.

• Install the Probe: Insert the probe into the housing. Set the recommended gap to 1.27 mm (50 mils) from the target.

• Apply Torque: Tighten the retaining nut to 29.5 N·m. Tighten the probe sleeve locknut to 39.3 N·m.

• Check Shaft Diameter: Ensure the shaft diameter is at least 50.8 mm minimum.

• Wire Correctly: Use shielded triax cable with tinned field wiring. Maximum field wiring length is 305 metres.

• Match Temperature Class: Select the correct temperature classification for your operating environment.

• Avoid Low Temperatures: Never expose the probe below -34°C to prevent seal failure.
