3300 XL 8mm Probe Bently Nevada 330195-02-12-90-CN

3300 XL 8mm Reverse Mount Probe 330195-02-12-90-CN

Product Introduction

The Bently Nevada 330195-02-12-90-CN represents the pinnacle of long-reach non-contact vibration and position sensing technology. As a distinguished member of the 3300 XL series, this 8 mm proximity probe delivers exceptional accuracy and signal integrity over extended cable runs up to 9.0 meters. Meanwhile, its reverse mount configuration offers valuable installation flexibility in complex, space-constrained machinery layouts. Specifically, this extra-long version suits large turbines, generators, and heavy industrial compressors where remote sensor placement is necessary. Furthermore, the 3300 XL 8 mm transducer carries CN agency approval, ensuring compliance with Chinese regulatory requirements. Consequently, this probe combines technical excellence with regional market readiness.

Technical Specifications

This 330195-02-12-90-CN model features an extended total length of 9.0 meters (29.5 feet) , accommodating the largest machinery installations. In addition, its case incorporates a standard 3/8-24 UNF thread with a maximum thread engagement of 0.563 inches. Moreover, the probe tip is manufactured from rugged Polyphenylene sulfide (PPS), which delivers excellent chemical resistance and thermal stability. Similarly, the probe case uses AISI 303 or 304 stainless steel (SST), providing superior corrosion protection in aggressive industrial environments. For electrical characteristics, the nominal probe DC resistance (RPROBE) from center conductor to outer conductor measures 9.87 ± 0.50 Ω for this 9.0-metre version. Therefore, this resistance value ensures proper impedance characteristics across the extended cable length.

Agency Approval and Compliance

The 330195-02-12-90-CN distinguishes itself with its CN country-specific agency approval option. For instance, this certification demonstrates full compliance with applicable Chinese industrial standards and regulatory frameworks. Meanwhile, this approval streamlines the procurement process for projects operating within China's regulatory environment. Additionally, the Bently Nevada 3300 XL probe meets rigorous IEC standards for humidity testing. Specifically, it shows less than a 3% change in Average Scale Factor (ASF) when tested at 93% relative humidity for up to 56 days, following IEC standard 68-2-3. This compliance ensures reliable operation in diverse and challenging environmental conditions.

Environmental and Mechanical Ratings

The Bently Nevada 3300 XL probe operates reliably across an impressively wide temperature spectrum. For the standard configuration, the operating and storage temperature ranges from -52°C to +177°C (-62°F to +350°F) . However, operators must note that exposing the probe to temperatures below –34˚C (-30˚F) may cause premature failure of the pressure seal. Nevertheless, the probe demonstrates outstanding humidity resistance in demanding conditions. Furthermore, the sealing mechanism uses a Viton® O-ring, which effectively seals differential pressure between the probe tip and the case. For more extreme thermal conditions, extended temperature range options are available upon request through the manufacturer.

Installation Guidelines

When installing the 330195-02-12-90-CN, technicians must follow specific procedures with extra care. First, inspect all threads thoroughly to ensure they remain clean and completely free from damage or debris. Next, verify that the thread engagement does not exceed the maximum of 0.563 inches. Furthermore, proper grounding is absolutely essential to prevent electrical interference from compromising the measurement signal. Meanwhile, route the probe cable with exceptional care, avoiding sharp bends, kinks, or excessive tensile stress over the 9.0-meter run. In addition, always adhere to the torque specifications documented in the system's installation manual. For this reason, the reverse mount design of this proximity probe may demand specific clearance adjustments within the mounting fixture. Finally, secure the cable at regular intervals to prevent mechanical strain on the connector.

Packaging and Logistics

Each unit of the Bently Nevada 330195-02-12-90-CN receives robust, premium packaging to prevent transit-related damage. Specifically, the standard packaging includes the probe itself along with its integral 9.0-meter cable and connector.
