31000-16-05-00-065-03-02

Features:

• External Mounting Housing for 3300 XL 8 mm Proximity Probes Through Machine Case
• Integrates PPS Housing Material with Corrosion-Resistant Stainless Steel Components
• Functions with Radial Vibration and Keyphasor Measurement Applications

The 31000-16-05-00-065-03-02 serves as the Proximity Probe Housing Assembly in industrial machinery monitoring systems, providing a protected mounting path for radially installed transducers used in vibration or Keyphasor measurements. It ships with an installed 3300 XL 8 mm probe with connector and includes a 0.5 m (20 in) probe cable for internal routing within the housing. The assembly provides a probe penetration of 6.5 inches through the machine case and is supplied with two plugs, one 3/4-14 NPT fitting, one 3/4-14 to 1/2-14 NPT SST reducer, and one cable seal grip with grommets accommodating cable sizes from 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches. The 3/4-14 NPT mounting thread secures the housing to the machine casing. The 31000-16-05-00-065-03-02 incorporates significant advantages over direct probe mounting by allowing external access to the proximity probe and its extension cable, enabling gap adjustment or probe replacement without disassembly of the machine.

The 31000-16-05-00-065-03-02 provides essential mechanical protection and alignment functions critical to the measurement path, directly affecting the accuracy of relative vibration signals in the overall monitoring system. One housing is required for each radially mounted proximity probe position, with the 3/4-14 NPT mounting thread ensuring secure penetration through the machine case. The housing occupies a dedicated through-case mounting position and must be positioned so that the probe sensing area aligns with the bearing journal; the machine casing must be affixed to the bearing to obtain an accurate relative vibration signal.

For intrinsically safe hazardous area applications, the 31000 monitoring system requires an approved transducer system and appropriate I.S. barriers installed in conjunction with the housing assembly. In addition to standard general-purpose mounting, the hazardous area configuration also performs environmental protection and signal integrity maintenance. The 31000 intrinsically safe implementation executes compliance using the API 670 standard specifications built into the housing design. Using this method, the polyphenylene sulfide housing and corrosion-resistant stainless steel elements continually protect the probe and cable interface from process exposure. If the system detects that the approved transducer components or I.S. barriers are not properly installed, the 31000-16-05-00-065-03-02 must not be operated in the hazardous area until the installation is fully compliant.
