Features:
- The documented value for probe and approvals is 3300 XL 8 mm probe with Multiple Approvals; the complete approval suffix must match the installation area and site requirements.
- The documented value for standoff adapter is 4.5 in (114.3 mm); retain this specification when matching the exact proxpac xl proximity transducer assembly and installed Bently Nevada 3300 hardware.
- The documented value for probe penetration is 2.0 in (50.8 mm); retain this dimension when checking mounting geometry, routing and compatibility with the installed hardware.
330880-28-45-020-03-02 is a Bently Nevada PROXPAC XL Proximity Transducer Assembly for the 3300 system. It measures shaft vibration or position without contact in a matched transducer chain. Key specifications: Probe and Approvals: 3300 XL 8 mm probe with Multiple Approvals; Standoff Adapter: 4.5 in (114.3 mm). Match the full order code and hardware before replacement.
This highly integrated, stand-alone design integrates the 3300 XL 8mm probe, housing, and Proximitor preamplifier sensor into a high-strength PPS (polyphenylene sulfide) anti-static housing, eliminating the need for extension cables and separate housings between the probe and preamplifier. Specific configuration parameters are as follows: -28 represents an 8mm probe with multiple explosion-proof certifications; -45 corresponds to a 4.5-inch bracket adapter; -020 corresponds to a 2.0-inch probe penetration depth; -03 includes a 3/4-14 NPT connector, stainless steel reducer, and plug accessory kit; -02 uses 3/4-14 NPT mounting threads. This assembly features a 4X type/IP66 industrial protection rating, operates from -17.5 to -26 Vdc, and outputs a voltage signal proportional to the gap (standard sensitivity 7.87 V/mm), making it widely applicable for monitoring vibration, displacement, and axial position in critical rotating machinery such as turbines and compressors.
The exact 330880-28-45-020-03-02 execution must be confirmed by its complete order code, condition, connected 3300 system and included scope before purchase or replacement.

Important Notice: Confirm the complete order code, hardware execution and connected system before replacement. Accessories, cables, calibration data, software and certificates are included only when stated in the written quotation.
Preserve every option block of 330880-28-45-020-03-02. Retained facts: Probe and Approvals: 3300 XL 8 mm probe with Multiple Approvals; Standoff Adapter: 4.5 in (114.3 mm); Probe Penetration: 2.0 in (50.8 mm). Mechanical length, thread, cable/connector and approval suffixes are part of the exact probe identity.
Match probe family, electrical length, extension cable and Proximitor Sensor. Confirm target material, available travel, nearby probe spacing and mounting geometry before exchange.
Set the operating gap from live bias voltage, support the cable above its bend limit and verify runout, vibration or position response against the commissioning baseline.
