Bently Nevada 21747-075-00 7200 Series Extension Cable

Description

The 21747-075-00 is an extension cable component designed for the 7200 proximity transducer system. This specific configuration features a 7.5 metre cable length and standard construction without protective armor. The cable acts as an electrical bridge between the 7200 series proximity probe and the Proximitor sensor, maintaining the characteristic impedance required for accurate displacement and vibration measurements.

Used in 7200 proximity transducer chains, this cable ensures signal integrity for shaft position and radial vibration monitoring on rotating machinery such as turbines, compressors, and electric motors. It is constructed to operate within a temperature range of -30 Celsius to +177 Celsius and is compatible with 5 mm and 8 mm 7200 series proximity probes.

Features

• 7.5 metre cable length (Option 075)
• Standard construction, without stainless steel armor (Option 00)
• Compatible with Bently Nevada 7200 series 5 mm and 8 mm proximity probes
• 95 Ohm characteristic impedance
• Operating temperature range: -30 Celsius to +177 Celsius

Applications

• Radial vibration measurement for bearing condition monitoring
• Axial thrust position measurement
• Rotor stability and eccentricity monitoring
• Suitable for rotating machinery including gas turbines, steam turbines, and centrifugal compressors

Installation Guidelines

When installing 7200 series extension cables, ensure the connection to the probe and Proximitor is tight to prevent signal degradation. Avoid sharp bends that exceed the minimum bend radius of the coaxial cable to maintain impedance stability. In hazardous environments, verify that the entire transducer chain (probe, extension cable, and Proximitor) meets the site-specific hazardous area classification requirements.
