Parameter Analysis

The 5-meter cable length is specifically matched to the 5-meter Proximitor sensor for optimal performance. The 11 mm probe diameter provides a linear measurement range suitable for most rotating machinery applications. The M16x1.5 thread allows secure mounting, and the stainless steel case ensures corrosion resistance. The PPS tip offers excellent dielectric properties and thermal stability.

Application Scenarios

This probe is ideal for monitoring vibration and axial position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in critical applications such as steam turbines, gas turbines, centrifugal compressors, and large electric motors to prevent catastrophic failures.

Installation Guide

Install the probe with recommended torque of 21.1 N•m (187 in•lb). Ensure the target surface is flat and has a minimum diameter of 30.5 mm (1.2 in) for flat surfaces, or a shaft diameter of at least 152 mm (6.0 in). Maintain a minimum bend radius of 25.4 mm for the cable. Connect using the ClickLoc connector, tightening finger tight, with maximum torque of 0.565 N•m (5 in•lb).

Compatibility

This probe is designed for use with Bently Nevada 3300 XL series Proximitor sensors, specifically the 5-meter version. It is compatible with 3300 and 3500 monitoring systems. Always verify system compatibility before installation.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Keep the probe tip clean and free from debris. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. Check connector tightness periodically.

Procurement Advice

When ordering, ensure the model number 330709-000-230-50-11-00 matches your requirements. Verify the total length and connector type. For genuine Bently Nevada parts, purchase from authorized distributors like TenBN to guarantee authenticity and warranty.

FAQ

What is the operating temperature range of this probe?

The operating and storage temperature range is -52°C to +177°C (-62°F to +351°F). However, exposure below -34°C may affect the pressure seal.

Can this probe be used with any Proximitor?

No, the 5-meter probe is designed specifically for use with the 5-meter Proximitor sensor only.

What is the recommended target size?

For flat surfaces, the minimum recommended diameter is 30.5 mm (1.2 in). For shafts, the minimum recommended diameter is 152 mm (6.0 in).

What is the probe DC resistance?

The resistance from the center conductor to the outer conductor is 7.2 ± 0.8 ohms.

Is this probe suitable for hazardous areas?

The probe has temperature classifications for various EPL ratings, but agency approval option is ’00’ meaning not required. Check specific area classification requirements.
