The Bently Nevada 21000-34-05-00-036-03-02 Proximity Probe Housing Assembly is an externally mounted aluminum proximity probe housing assembly for use with 3300 XL 8 mm proximity probes with connector protector and multiple approvals. The 21000 series housing assemblies provide mechanical protection, probe positioning, cable sealing, and external access for proximity probes installed on critical rotating machinery.

The Bently Nevada 21000-34-05-00-036-03-02 Proximity Probe Housing Assembly configuration includes a 3300 XL 8 mm probe with connector protector, a 0.5 m (20 in) probe cable, no standoff adapter, a 3.6 inch probe penetration length, a cable seal grip fitting assembly, and a 3/4-14 NPT mounting thread. It is commonly applied in turbine, compressor, pump, and generator monitoring systems where reliable shaft vibration and position measurement are required.

The 21000-34-05-00-036-03-02 Bently Nevada Proximity Probe Housing Assemblies may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
The 21000-34-05-00-036-03-02 features a 3.6-inch (91.4 mm) probe sleeve length with adjustable probe penetration, providing an adjustment range of ±0.5 inch (13 mm) to accommodate various machine case thicknesses and mounting requirements. For probe penetration lengths between 1.0 and 2.0 inches, it may be necessary to counter bore the machine case to reduce probe side view or rear view, as noted in the installation guidelines for the 21000-34-05-00-036-03-02.
The 21000-34-05-00-036-03-02 is rated as a CSA explosion-proof enclosure and is certified as a CSA Type 4 enclosure, providing protection against dust, water, and hazardous atmospheres. The 21000-34-05-00-036-03-02 is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probes, ensuring it meets the stringent requirements of the oil and gas and petrochemical industries for machinery condition monitoring.

Check Penetration (3.6 inches): Ensure that your machine port clears any internal obstructions across the fixed 3.6-inch penetration depth to avoid crushing the probe tip.
Apply Thread Sealant: Apply a suitable thread lubricant or Teflon tape to the 3/4-14 NPT mounting threads of the housing sleeve.Thread Housing Body: Screw the housing sleeve into the machine case port. Tighten securely to ensure a process seal.
Gap Adjustment: Unscrew the housing's dome cover to access the internal reverse-mount probe. Loosen the probe locknut and rotate the probe body to adjust the physical gap distance between the probe tip and the target shaft.
Lock Probe: Use a voltmeter to verify the target gap voltage (typically -10 VDC for a normal 80-mil gap mid-range setup). Tighten the locknut to secure the probe's position.
