Description

The 21000-16-05-00-073-04-02 is a robust proximity probe housing assembly designed for industrial machinery protection, featuring a 3300 XL 8 mm proximity probe configuration. This assembly provides environmental protection and secure mounting for proximity probes, utilizing an aluminum body construction with a stainless steel sleeve to ensure durability in demanding operational conditions. This specific variant includes a 0.5 m cable length, a 7.3-inch probe penetration depth (Option 073), and a 3/4-14 NPT mounting thread with a plug fitting.

Engineered for compliance with API 670 standards, this housing protects the transducer probe against physical damage while maintaining the precise alignment required for shaft vibration and axial position monitoring. The 21000 series is ideal for use in hazardous areas when ordered with appropriate options, providing a reliable interface between the machine case and the monitoring system. The assembly includes specialized fittings for conduit entry, ensuring a sealed environment for the probe lead and connector system.

Features

  • Configuration: 3300 XL 8 mm proximity probe (Option 16)
  • Cable Length: 0.5 m (Option 05)
  • Standoff Adapter: None (Option 00)
  • Probe Penetration: 7.3 inch depth (Option 073)
  • Fittings: One 3/4-14 NPT plug (Option 04)
  • Mounting Thread: 3/4-14 NPT (Option 02)
  • Construction: Aluminum body with 304 stainless steel sleeve
  • Compliance: Designed to meet API 670 requirements for externally mounted proximity probe housings

Applications

  • Shaft vibration and axial position measurement
  • Centrifugal pumps and compressors
  • Steam and gas turbines
  • Industrial motors and gearboxes
  • Critical rotating machinery protection systems

Installation Guidelines

Ensure the housing is installed using a 3/4-14 NPT thread connection to the machine case. For probe penetration depths greater than 300 mm (12 in), auxiliary sleeve support is required to mitigate vibration-induced resonance. Ensure all fittings are properly torqued to maintain environmental integrity. If the probe penetration is between 1.0 and 2.0 inches, counter-boring the machine case may be necessary to minimize side-view effects on the probe output.

Compliance and Certifications

  • RoHS Directive 2011/65/EU
  • API 670 Standard compliance for probe housings

FAQ

What does the 073 code represent in this 21000 series part number?

The 073 code specifies a probe penetration depth of 7.3 inches (approximately 185 mm) as defined in the ordering options for the probe penetration length.

Is this housing assembly compatible with 3300 XL 8 mm probes?

Yes, the 16 option in the part number specifically indicates that this assembly is configured for the 3300 XL 8 mm proximity probe.

Does the 21000-16-05-00-073-04-02 include explosion-proof fittings?

No, the 04 option indicates that the assembly includes only one 3/4-14 NPT plug and does not include the explosion-proof fittings found in other configuration options.

What is the weight of the 21000 housing assembly?

The typical weight of the 21000 housing assembly without fittings is 1.1 kg (2.4 lb).
