        Overview Manuals Specifications Application Diagnostic & Protection Installation Guidelines

        Features:

        • 2‑conductor 22 AWG with overall shield; rejects common‑mode noise and blocks electrostatic interference for clean sensor signals.
        • 2‑socket female connector mates directly with Velomitor sensors; sealing prevents moisture ingress in humid industrial environments.
        • Suitable for outdoor and high‑temperature turbine applications; compatible with Bently Nevada 3500 and 1900 monitors.
        The 9571-66 is a 2‑conductor twisted, shielded cable specifically designed for low‑level piezoelectric signals from Velomitor velocity sensors. The twisted pair construction ensures that any electromagnetic interference (EMI) picked up along the cable length is common to both conductors and is rejected by the differential input of the monitor. The overall shield (typically a foil or braid) provides an additional layer of protection against electrostatic noise from nearby variable frequency drives, contactors, and power cables. Without proper shielding, the sensor’s millivolt‑level output can be overwhelmed by noise, causing false alarms or missed vibration data.

        The 9571-66 features a MIL‑C‑5015 style connector at the sensor end – a 2‑socket female connector that mates with the 2‑pin receptacle on Bently Nevada Velomitor sensors. This connector type is widely used in industrial and military applications because of its rugged construction and environmental sealing. The connector shell is typically made of anodized aluminum or stainless steel, with a neoprene or silicone insert that seals around the pins/sockets. When mated and tightened, the connector provides a moisture‑resistant seal, protecting the electrical contacts from humidity, condensation, and splashing water.

        The 9571-66 is rated for continuous operation from -50°C to +120°C. This wide temperature range matches the operating limits of Bently Nevada Velomitor sensors, allowing the entire sensor‑cable system to be deployed in extreme environments. In a typical gas turbine installation, the sensor may be mounted on the bearing housing where temperatures reach 100°C. In a steam turbine, the casing may be hot during operation, but the cable must also survive freezing conditions during plant shutdowns in winter climates. The cable’s insulation and jacket are selected from materials (e.g., Teflon, PFA, or cross‑linked polyethylene) that remain flexible at low temperatures and do not melt or degrade at high temperatures.

        The 9571-66 Bently Nevada Interconnect Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

        • Power Generation: Monitoring casing vibration on steam turbines, gas turbines, and generators.
        • Oil & Gas: Critical for centrifugal/reciprocating compressors and large pump sets.
        • Petrochemical: Monitoring fans, blowers, and motors in harsh chemical environments.
        • Signal Integrity: Features 2-conductor twisted shielded wire (22 AWG) to minimize Electromagnetic Interference (EMI), ensuring precise vibration data is transmitted.
        • System "OK" Monitoring: The 3500 system monitors the continuity of this cable. If the cable is cut or shorted, the system triggers a "NOT OK" status, preventing false trips and alerting maintenance.
        • Condition Monitoring: It supports the transmission of dynamic waveforms required by System 1 software for diagnosing machine faults like imbalance, misalignment, or bearing wear.
        • Connector Orientation: Typically features a 2-socket moisture-resistant connector at the sensor end and terminal lugs at the monitor end.
        • Mechanical Protection: It is highly recommended to run the cable through rigid or flexible conduit to prevent physical damage from foot traffic or moving machinery.
        • Grounding: To avoid ground loops, the shield should be grounded at the monitor end only (usually at the 3500 I/O module terminal strip).
        Description
        The 9571-66 is an interconnect cable designed for Bently Nevada Velomitor Piezo‑velocity Sensors. It is a 2‑conductor twisted, shielded 22 AWG cable with a 2‑socket moisture‑resistant female connector at one end (mates to the sensor) and terminal lugs at the other end for connection to monitors. 

        When using the 9571-66, engineers can connect a Velomitor sensor to a Bently Nevada 3500 or 1900 monitor. The cable’s twisted pair and shielding provide excellent noise rejection, essential for low‑level piezoelectric signals. The moisture‑resistant connector ensures reliable operation in humid or wet industrial environments. 

        The 9571-66 has a minimum length of 2 feet and a maximum length of 99 feet. The operating temperature range is -50°C to 120°C. For armored applications, use the 84661 series cable. For connections requiring a right‑angle plug, use the 89477 series cable. 

        For legacy Bently Nevada system expansions, the 9571-66 provides a direct replacement cable for Velomitor sensors. Always check the total cable length between the sensor and monitor does not exceed 305 meters (1,000 feet) to avoid signal degradation. The cable is not approved for use with the 21128 housing; use 89477‑XX for that application. 
        Alternative Names
        84661-66 89477-66 125065-66
        Technical notes
        The 9571-66 maximum length is 99 feet (30 meters) . However, the Velomitor sensor can drive up to 305 meters (1,000 feet) of total cable (including extension cables). For longer runs, use a bulk cable (e.g., 02173006) and field‑installable connectors.The cable’s operating temperature range is -50°C to +120°C, matching the Velomitor sensor’s range.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Does 9571-66 reduce electrical noise?
        Yes. The 9571-66 uses twisted pair construction to reject common‑mode noise and an overall shield to block electrostatic interference. This preserves the low‑level piezoelectric signal from the Velomitor sensor, ensuring accurate vibration data even in electrically noisy environments with VFDs and motors.
        What lengths are available for 9571-66?
        The 9571-66 indicates a 66‑foot length (the last two digits). Standard lengths from 2 to 99 feet are available in 1‑foot increments. Minimum standard length is 2 ft (0.6 m); maximum is 99 ft (30 m). For armored cable, use the 84661 series.
        What connector does 9571-66 have at the sensor end?
        The 9571-66 has a 2‑socket moisture‑resistant female connector (MIL‑C‑5015 type), which mates directly with the 2‑pin MIL‑C‑5015 receptacle on Bently Nevada Velomitor sensors. The monitor end has terminal lugs for screw termination.
        Can 9571-66 be used with the 21128 Velocity Transducer Housing?
        No. The 9571-66 is not for use with the 21128 housing. For applications requiring the 21128 housing, order the 89477 series cable (e.g., 89477-66), which has a right‑angle plug and heavier 18 AWG conductors.
