Configured for physical protection and environmental isolation of proximity probes within TSI platforms, the Bently Nevada 21000-16-05-00-105-03-02 (21000 Proximity Probe Housing Assemblies) provides direct physical/electrical execution. The mechanical enclosure permits external access, depth adjustment, and online removal of proximity sensors during machine operation, preventing high-pressure lubrication oil leakage or process gas bypass across the machine casing boundary layer.

Structural Dimensional Specs

Eddy-Current Probe Scaling and Rotor Dynamics Stability

The housing assembly maintains the rigid physical orientation and concentric alignment of the internal proximity probe tip relative to the target shaft. This structural stability is necessary to perform accurate gap voltage validation (-10 VDC targets) during machinery monitoring system commissioning. By locking the sensor securely inside the 10.5 in stilling well sleeve, the assembly prevents side loading and deflection caused by turbulent bearing oil flow, maintaining constant eddy-current probe scaling and optimizing cross-talk suppression between radial pairs tracking complex rotor dynamics.

Dispatch Logistics Manifest

• One (1) Bently Nevada 21000 aluminum housing dome cover and base assembly

• One (1) Integrated 10.5 in steeling well sleeve segment

• One (1) Internal probe compression sleeve locking block with hardware

• Two (2) High-performance internal fluorocore sealing rings

Mechanical Installation and Cabling Guidelines

• Thread the primary 1/2-14 NPT housing adapter into the machine bearing casing port, ensuring a minimum engagement of 5 full NPT threads to form a fluid-tight seal.

• Guide the passive proximity probe down the internal channel of the 10.5 in stilling well sleeve, taking care not to scrape or twist the integrated coaxial lead line.

• Connect an external digital voltmeter up to the Proximitor signal lines to track active field potentials while adjusting the mechanical sleeve depth.

• Tighten the internal locking hardware onto the probe body once the loop output matches the designated -10 VDC gap validation center coordinate.

• Seal the outer conduit connections using certified thread compound and torque the heavy dome cover completely down to prevent moisture or corrosive gas ingress.

Procurement Logistics & Protective Packaging

Delivery time: 2-7 days when payment finish, routed via expedited international courier channels utilizing DHL, FEDEX, or UPS. Internal components are enclosed within heavy-walled moisture-vapor barrier anti-static industrial packaging boundaries. Exterior shipments feature double-wall corrugated protective master cartons fitted with custom-molded shock-absorbing polyurethane foam structures to maintain exact mechanical thread and sleeve tolerances during international delivery.

Technical Engineering FAQ

Q: Can an 11 mm diameter proximity probe be mounted inside this specific 21000 housing model?

A: No. The internal sleeve arrangement, unthreaded length (-16), and stilling well parameters are explicitly matched to standard 8 mm proximity probe casing geometries. An 11 mm probe requires an alternative internal dimension selection to avoid structural interference.

Q: What step must be performed if process fluid is discovered inside the terminal housing dome?

A: Fluid inside the dome indicates a failure or wear of the internal dynamic seals. The machine process must be isolated or bypassed so the damaged seals can be extracted and replaced to stop the fluid from bypassing the barrier.

Q: Is a special alignment tool required to ensure the probe tip does not contact the sides of the stilling well?

A: No special tools are needed. The internal guide tracks and compression sleeve are machined to align the probe concentrically within the 10.5 in stilling well, provided the external 1/2-14 NPT thread is tracked straight into the port.
