Description
21000-28-05-00-076-04-02 is a Proximity Probe Housing Assembly designed to provide reliable mechanical mounting and environmental protection for probes used in vibration and displacement monitoring systems. The model 21000-28-05-00-076-04-02 is typically applied in rotating machinery monitoring environments, offering a stable installation structure for the 3300 XL 8 mm probe and supporting selectable hazardous area approvals for continuous industrial operation.

In terms of probe configuration, 21000-28-05-00-076-04-02 is supplied with a Probe with Connector featuring a 3300 XL 8 mm probe, with selectable hazardous area certifications to meet safety compliance requirements under various operating conditions. The probe cable length is 0.5 m (20 in.), making it suitable for short-distance local installations while helping minimize signal attenuation and improve measurement stability.

From a structural perspective, 21000-28-05-00-076-04-02 is built without a standoff adapter, providing a direct-mount configuration. The probe penetration is 7.6 in., which satisfies common shaft vibration monitoring depth requirements. The assembly includes one 3/4-14 NPT plug only, used for sealing and interface management.

Regarding mounting options, 21000-28-05-00-076-04-02 does not include an additional mounting thread option (Mounting Thread Option: No). The overall design emphasizes standardization and simplified installation, making it suitable for industrial monitoring systems where existing mounting conditions are already compatible.
