Probe Construction

The probe tip material is Polyphenylene Sulfide (PPS). The  material is AISI 304 stainless steel. The probe cable is 1-meter length of 75 Ω triaxial type. The cable insulation is fluoroethylene propylene (FEP). The probe connector is a gold-plated brass ClickLoc type. Probe tensile strength is 330 N maximum between cable and case.

Housing Construction

The housing material is UV-resistant glass-reinforced PPS. This thermoplastic contains conductive fibers. Sleeve material and retaining chain are AISI 304 stainless steel. Outer sleeve and retaining screws are AISI 303 stainless steel. Sleeve O-ring material is neoprene. Grounding liner and retaining plate are AISI 304 stainless steel. Vibration isolation material is extra soft cellular silicone.

Housing Ratings

The IP66 rating is verified by BASEEFA report number T07/0709. Housing impact strength is certified by BASEEFA for two separate 4 Joule impacts. Testing occurred at -39°C and at 115°C. CSA verified samples withstand 7 Joule impact at room temperature.

Recommended Torque Values

The retaining nut torque is 29.5 N·m (260 in·lb). The probe sleeve locknut torque is 39.3 N·m (350 in·lb). These values ensure proper installation and reliability.

Probe Temperature Range

The operating temperature range is -51°C to +177°C. Exposing the probe to temperatures below -34°C may cause premature seal failure. Follow all temperature guidelines for reliable operation.

Power Requirements

The Bently Nevada 330880-28-15-089-03-02 requires -17.5V dc to -26V dc without barriers. Maximum consumption is 12 mA. With barriers, the range is -23V dc to -26V dc. Operation above -23.5V can reduce linear range. Supply sensitivity is less than 2 mV change per volt change.

Measurement Specifications

The linear range is 2 mm (80 mils). The range begins at approximately 0.25 mm from the target. The range extends from 0.25 mm to 2.3 mm (10 to 90 mils). This corresponds to approximately -1V dc to -17V dc. The recommended gap setting is 1.27 mm (50 mils).

Incremental Scale Factor (ISF)

The ISF is 7.87 V/mm (200 mV/mil) ±5%. This includes interchangeability error. Measurement uses increments of 0.25 mm over 80 mil range. Temperature range for this specification is 0°C to +45°C.

Frequency Response

The frequency response is 0 to 10 kHz at +0, -3 dB. This applies with up to 305 meters of field wiring. Field wiring should be 0.2 to 1.5 mm² (16 to 24 AWG). Use 3-conductor shielded triax cable for best results.

Target Requirements

The minimum target size is 15.2 mm diameter for a flat target. The minimum shaft diameter is 50.8 mm.

Installation Guidelines for the 330880-28-15-089-03-02

Mount the Bently Nevada 330880-28-15-089-03-02 using 3/4-14 NPT threads. Use the included reducer for 1/2-14 NPT connections. Apply 29.5 N·m torque to the retaining nut. Apply 39.3 N·m torque to the probe sleeve locknut. Set the probe gap to 1.27 mm (50 mils) recommended. Use 3-conductor shielded triax cable for field wiring.
