Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
The 21000-16-05-00-085-03-01 is a 21000 series proximity probe housing assembly configured with a 3300 XL 8 mm proximity probe (Option 16), a 0.5 meter probe cable (Option 05), and no standoff adapter (Option 00). This specific assembly features an 8.5 inch probe penetration depth (Option 085), an integrated cable seal grip with grommets (Option 03), and a 3/4-14 NPT mounting thread (Option 01).
Designed for industrial rotating machinery, this housing protects the probe assembly while maintaining the alignment required for accurate displacement and vibration measurements. The 21000 series utilizes an aluminum body with a 304 stainless steel sleeve, ensuring compatibility with standard hazardous area requirements and providing robust environmental protection for the transducer installation.
This proximity probe housing assembly is used in heavy industry to protect eddy-current transducers in vibration and position monitoring systems. Common applications include centrifugal compressors, steam and gas turbines, pumps, and motors where critical shaft vibration, axial position, and speed measurements are required.

| Manufacturer | Bently Nevada |
| Part Number | 21000-16-05-00-085-03-01 |
| Body Material | Aluminum |
| Sleeve Material | 304 Stainless Steel |
| Weight | 1.1 kg (2.4 lb) typical (without fittings) |
| Temperature Range | -51 degC to +177 degC (-60 degF to +351 degF) |
| Mounting Thread | 3/4-14 NPT |
Ensure the housing is installed using appropriate thread sealant for the 3/4-14 NPT connection. When routing the cable, utilize the cable seal grip to prevent moisture ingress. Verify that probe penetration depth allows for the recommended gap setting as specified in the 3300 XL transducer system documentation. If penetration exceeds 300 mm (12 in), additional sleeve support is required to prevent resonance.
