Reverse Mount Probe 330195-02-12-10-CN Bently Nevada

3300 XL 8mm Reverse Mount Probe 330195-02-12-10-CN

Product Introduction

The Bently Nevada 330195-02-12-10-CN sets the standard for non-contact vibration and position monitoring in turbomachinery. As a key member of the 3300 XL series, this 8 mm proximity probe delivers exceptional accuracy and long-term stability. Meanwhile, its reverse mount configuration provides installation flexibility in space-constrained applications. Specifically, engineers rely on this model for steam turbines, centrifugal compressors, and large motor bearings. Furthermore, the 3300 XL 8 mm transducer features CN agency approval, which satisfies specific regulatory requirements for the Chinese market. Consequently, this probe offers both technical excellence and regional compliance.

Technical Specifications

This 330195-02-12-10-CN model features a total length of 1.0 metre (3.3 feet) , which suits medium-range 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 uses rugged Polyphenylene sulfide (PPS), a material known for excellent chemical and thermal resistance. Similarly, the probe case is manufactured from AISI 303 or 304 stainless steel (SST), ensuring durability in harsh environments. For electrical performance, the nominal probe DC resistance (RPROBE) from center conductor to outer conductor measures 7.59 ± 0.50 Ω for this 1.0-metre version. Therefore, this value ensures accurate system calibration and consistent measurement outputs.

Agency Approval and Compliance

The 330195-02-12-10-CN distinguishes itself with its CN country-specific agency approval option. For instance, this certification demonstrates compliance with applicable Chinese industrial standards and regulations. Meanwhile, this approval simplifies the procurement process for projects operating within China's regulatory framework. 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 environmental conditions.

Environmental and Mechanical Ratings

The Bently Nevada 3300 XL probe operates effectively 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 excellent humidity resilience, as mentioned previously. 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.

Installation Guidelines

When installing the 330195-02-12-10-CN, technicians should follow several critical steps carefully. First, inspect the threads thoroughly to ensure they remain clean and completely free from damage. Next, verify that the thread engagement does not exceed the maximum of 0.563 inches. Furthermore, proper grounding is essential to prevent electrical interference from corrupting the measurement signal. Meanwhile, route the probe cable and connector with care, avoiding sharp bends and excessive tensile stress. 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, perform a continuity check before energizing the monitoring system.

Packaging and Logistics

Each unit of the Bently Nevada 330195-02-12-10-CN receives careful packaging to prevent transit-related damage. Specifically, the standard packaging includes the probe itself along with its integral cable and connector. We also employ anti-static materials to protect the sensitive tip and connector contacts. Moreover, all orders are dispatched using premium, expedited shipping services. Therefore, we partner with global carriers such as FedEx, UPS, and DHL. Consequently, your critical measurement device arrives safely and promptly, minimizing any disruption to your maintenance schedule.
