Bently Nevada 330730-040-02-05 3300 XL Extension Cable

The 330730-040-02-05 extension cable ensures stable signal transmission between probe and sensor.

This 4.0-meter cable is designed for 11 mm 3300 XL proximity probe systems.

It includes a connector protector to improve durability in humid or moist environments.

Gold-plated brass connectors maintain low contact resistance and long service life.

The cable uses FEP insulation for excellent heat and chemical resistance in harsh areas.

Optional flexible 302 stainless steel armor adds physical protection in tough installations.

The 330730-040-02-05 supports FluidLoc options to prevent fluid leakage through cable paths.

It meets multiple agency standards for safe use in industrial and hazardous locations.

The 330730-040-02-05 has a total length of 4.0 meters (13.1 feet).

It is built for 11 mm 3300 XL proximity probe systems with standard triaxial design.

Connector option 02 includes a protector for improved environmental sealing.

Agency option 05 provides multiple certification for global industrial applications.

Typical capacitance is 69.9 pF/m (21.3 pF/ft) across the entire cable length.

Core conductor resistance (RCORE) is 1.0 ±0.25 ohms for 4.0 meters.

Jacket conductor resistance (RJACKET) is 0.3 ±0.1 ohms for the same length.

Characteristic impedance is 75 Ω for stable high-frequency signal performance.

Operating and storage temperature ranges from -51°C to +177°C (-60°F to +351°F).

Standard non-armored weight is 45 g/m, totaling 0.18 kg for the full length.

Armored version weight is 140 g/m, reaching 0.56 kg for 4.0 meters.

Maximum tensile strength reaches 270 N at probe-to-extension connectors.

Gold-plated brass connectors ensure reliable electrical contact over time.

Field wiring supports 16 to 24 AWG with recommended three-conductor shielded cable.

Maximum system distance between sensor and monitor is 305 meters.

Incremental Scale Factor is 3.94 V/mm ±10% over the 4.0 mm linear range.

Recommended probe gap setting is 2.5 mm for optimal linear performance.

Connect the 330730-040-02-05 between the 3300 XL probe and proximitor sensor.

Attach the connector protector to shield joints from moisture and physical damage.

Use silicone tape if preferred, but avoid it in turbine oil exposure environments.

Route the cable away from sharp edges and high-temperature surfaces when possible.

Maintain bending radius within limits to protect internal conductors and insulation.

For armored versions, ensure flexible steel armor does not get pinched or crushed.

Ground the cable shield properly to reduce electrical noise and interference.

Do not exceed maximum tensile force during pulling or mounting operations.

Verify total system length stays within recommended values for best frequency response.

Confirm all connections are tight before powering the measurement system.
