Functional Description

330701-00-20-10-11-00 is a Proximity Probe Sensor manufactured by Bently Nevada. It is a part of 3300 XL series, which is known for high performance and reliability in vibration monitoring and machinery protection systems. Proximity probes are used to monitor the vibrational movements of critical components like the turbine shaft, bearings, and rotor. They provide real-time data on vibrations, which is essential for early detection of mechanical faults such as imbalance, misalignment, or bearing wear. Excessive vibration can indicate a potential failure, triggering alarms or corrective actions to prevent damage.

Features

• Probe Type: The 3300 XL 11 mm Probe is designed for precise and reliable proximity measurements. It comes with a 1/2-20 UNF thread, and is without armor, providing flexibility and ease of installation in various machinery.
• Unthreaded Length Option:
  • 00 = 0.0 in: This indicates that there is no unthreaded portion on the probe, making it suitable for mounting in tight spaces where thread is required from the start.
    Overall Case Length Option:
  • 20 = 2.0 in: The length of the probe’s casing is 2.0 inches, ensuring the probe fits into specific machine configurations and allowing for precise measurements without excess bulk.
• Total Length Option:
  • 10 = 1.0 metre (3.3 feet): The total length of the sensor, including the cable, is 1 meter, making it versatile for a variety of applications. The 3.3 feet length provides enough reach for most installations.
• Connector and Cable-Type Option:
  • 02 = Miniature coaxial ClickLoc connector, standard cable: This sensor is equipped with a ClickLoc connector, which is miniature and provides a reliable and secure connection. The cable is a standard coaxial cable, designed to maintain the integrity of the signal over extended distances.
• Agency Approval Option:
  • 00 = Not required: This option indicates that the sensor does not require agency approval for its use in general applications. However, users should check specific regulatory requirements in their location or industry.
• Probe Tip Material: The probe tip is made of Polyphenylene sulfide (PPS), a high-performance plastic material known for its resistance to chemicals, heat, and abrasion, ensuring longevity and stability under harsh operating conditions.
• Probe Case Material: The probe case is constructed from AISI 304 stainless steel (SST), providing durability, corrosion resistance, and the ability to withstand a wide range of environmental conditions.
• Probe Cable Specifications: The cable used with the probe is a 75-ohm triaxial cable, with fluoroethylene propylene (FEP) insulation. The FEP insulation is highly resistant to temperature extremes and chemicals, making it ideal for tough environments. The cable is available in three different lengths: 1 metre (3.3 feet), 5 metres (16.5 feet), or 9 metres (29.5 feet), giving users flexibility based on their application needs.
• Operating and Storage Temperature: The sensor is designed to operate within a temperature range of -51°C to +177°C (-60°F to +351°F), allowing it to function in extremely hot or cold environments, making it suitable for a variety of industrial applications worldwide.
• Probe Pressure: The 3300 XL probes are designed to seal differential pressure between the probe tip and the case, using a Viton O-ring for sealing. This makes the probe capable of handling conditions where pressure differences may be present, ensuring the sensor remains reliable under varying pressures. However, the probes are not pressure tested before shipment. If pressure sealing is a critical requirement for your application, Bently Nevada’s custom design department can perform pressure seal tests as needed.

Installation and Use

This sensor is easy to install, with the ClickLoc connector ensuring secure and quick connections to the monitoring system. The cable options provide flexibility in distance, and the durable materials ensure the sensor can withstand harsh operating conditions. However, proper handling and care should be taken to avoid static discharge during installation, especially with sensitive components like the sensor’s Polyphenylene sulfide (PPS) tip.
