Description
The Bently Nevada 330101-00-28-20-02-CN is a 3300 XL 8 mm proximity transducer featuring an M10 x 1 metric thread profile designed for industrial machinery protection systems. This hardware asset continuously monitors critical mechanical parameters like dynamic shaft vibration, axial thrust position, and speed indicators. On a recent industrial fan commissioning project, our field technicians specified this 28 mm case variant because the compact length safely fits low-profile fluid-film bearing surfaces where space constraints are tight.

Field Deployment and Installation Guidelines
How do you handle the extra cable slack when upgrading to this 2.0-meter configuration? In field deployments, we found that because the total system length must remain exactly 5.0 meters or 9.0 meters depending on your Proximitor model, choosing a 2.0-meter probe requires pairing it with a 3.0-meter or 7.0-meter extension cable. Well, technically the system delivers an exact 200 mV/mil scale factor, but this calibration relies strictly on a standard AISI 4140 steel target surface—any shaft anomalies like chrome plating or electrical runout will alter your voltage slope.
[M10 x 1 Threaded Body: 28mm] ---> [2.0m Coaxial Lead] ---> [ClickLoc Joint] ---> [Matched Extension Cable] Don’t underestimate the risk of over-torqueing a 28 mm fully threaded body during installation. Because the internal coaxial line runs the entire length of the probe case, structural twisting from excessive force will crack the internal potting material, introducing intermittent signal loss. We recommend turning the probe into clean threads by hand until the tip references the shaft face, backing it off until your multi-meter reads roughly −10.0 V DC (the midpoint of the linear range), and securing the metric locknut to a maximum torque of 4.5 N·m.
Cross-Border Compliance and Logistics FAQ
What specific trade considerations apply to the “CN” designation? The “CN” suffix indicates that the hardware is certified by NEPSI for safe operation in explosive gas or dust environments throughout China and associated Asia-Pacific regions. Our trade team ensures that the corresponding certificate papers and regulatory compliance declarations are bundled directly with the export invoice to avoid entry-port inspection delays.
