Bently Nevada 330190-085-00-05 3300 XL Extended Temperature Range Extension Cable

Description

330190-085-00-05: 3300 XL Extended Temperature Range (ETR) extension cable, specifying an 8.5-meter length (Option 085) with standard unarmored construction (Option 00) and CSA, ATEX, and IECEx hazardous area approvals (Option 05). This component is designed for demanding proximity transducer installations where temperatures exceed the thresholds of standard cabling systems. The extension cable operates as a medium between the proximity probe and the Proximitor Sensor, conveying high-frequency eddy-current signals to measure shaft vibration, axial position, and speed on critical rotating machinery.

In contrast to armored ETR options such as Option 01, this variant (Option 00) features a standard unarmored PFA-insulated cable with a maximum outside diameter of 3.7 mm. Standard temperature extension cables (model 330130) are rated up to 177 Celsius (350 Fahrenheit), whereas this 330190 ETR cable provides an extended temperature rating of up to 260 Celsius (500 Fahrenheit). It uses gold-plated ClickLoc coaxial connectors on both ends to construct a secure and low-resistance signal path that remains stable under high vibrational stresses, matching the calibration performance of standard 3300 XL Proximitor Sensors without requiring manual recalibration.

Features

• Option 085 specifies an 8.5-meter (27.9 feet) overall cable length, designed to combine with compatible probes to complete a 9.0-meter proximity transducer system.
• Option 00 provides a standard unarmored cable design featuring PFA insulation and a maximum outside diameter of 3.7 mm.
• Option 05 provides CSA, ATEX, and IECEx certifications for use in hazardous areas.
• PFA insulation material supports a continuous operating and storage temperature range of -51 Celsius to +260 Celsius (-60 Fahrenheit to +500 Fahrenheit).
• Gold-plated ClickLoc coaxial connectors require only finger-tight torque and feature an integrated locking mechanism to prevent loosening from vibration.
• Built-in CableLoc design provides a secure mechanical connection with high pull strength between the cable and connectors.

Applications

• Shaft vibration and position monitoring in steam turbines, gas turbines, and generators.
• Machinery protection systems in hydrocarbon processing plants and petrochemical facilities.
• High-temperature rotating machinery monitoring where ambient temperatures exceed 177 Celsius.
• Turbo-compressor and gearbox diagnostic monitoring.

Installation Guidelines

• Finger-tighten the gold "click" type connectors until they click to lock in place. No special tools are required.
• Do not exceed the minimum cable bend radius of 25.4 mm (1.0 in) during installation to prevent damage to the internal coaxial conductors.
• If running through conduit, standard practice is to use connector protectors to safeguard against entry of dust and moisture.
• Ensure the sum of the extension cable length and the probe length matches the calibrated length of the Proximitor Sensor (e.g., 9.0-meter total system length).

Compliance and Certifications

• CSA: Intrinsically Safe and Non-Incendive approvals for hazardous locations.
• ATEX/IECEx: Ex ia IIC T5...T1 Ga for intrinsically safe installations in Zone 0/1/2.
• CE: Compliant with relevant European directives.
