Quick Detail

Description

The 31000-28-05-70-066-00-02 Proximity Probe Housing Assembly is engineered for precision mounting of 3300 XL 8 mm Proximity Probes in automated monitoring and control systems. Constructed from high-strength PPS thermoplastic with conductive fibers, and reinforced with AISI 304/303 stainless steel sleeves and screws, this assembly ensures robust mechanical protection while resisting corrosion in industrial environments. Certified Type 4X by CSA, the housing withstands extreme conditions from -39°C to +115°C (-38°F to 239°F) and multiple impacts of 4 Joules, providing durability under harsh operating environments. With a standoff adapter of 7.0 in and probe penetration of 6.6 in, the housing supports optimal probe positioning for accurate vibration, position, and Keyphasor measurements. The 0.5 m probe cable with connector protector allows external access for gap adjustment or probe replacement without disassembling machinery. Fully compliant with API 670 standards, this assembly supports intrinsically safe operation in hazardous areas when paired with approved transducers and I.S. barriers, ensuring reliable automation monitoring in critical industrial applications.

Applications

1. Radial Vibration Monitoring in Rotating Machinery
The housing enables radial mounting of 3300 XL probes on turbines and compressors, allowing precise vibration detection within a 2 mm linear range, essential for automated condition-based maintenance.

2. Shaft Position Measurement in Pumps
External access provided by the housing facilitates probe gap calibration without dismantling machinery, maintaining measurement accuracy within ±2%, which enhances operational reliability and reduces downtime.

3. Keyphasor Reference Signal Acquisition
Supports installation of probes for real-time Keyphasor signals, allowing automated speed and phase monitoring in generators and centrifugal compressors for precise rotor tracking.

4. Harsh Industrial Environments
PPS thermoplastic and stainless steel construction ensures reliable operation in chemical, petrochemical, or offshore plants, maintaining Type 4X protection and continuous monitoring under extreme temperatures.

5. Intrinsically Safe Hazardous Area Monitoring
When combined with approved I.S. barriers, the housing can be safely used in Class I, Division 1 or Zone 1 hazardous areas, enabling automation monitoring in high-risk industrial settings.

Specifications

Competitive Advantage

1. High Mechanical Impact Resistance
Certified by BASEEFA to withstand two separate 4 Joule impacts, the housing protects sensitive probes from mechanical shock, reducing downtime and maintenance costs.

2. Corrosion-Resistant Materials
Constructed from PPS thermoplastic and stainless steel, the housing offers long-term durability in chemically aggressive or marine environments, outperforming conventional housings.

3. External Probe Access
Design allows gap adjustment and probe replacement without disassembly, cutting maintenance time by up to 30% and supporting uninterrupted automated monitoring.

4. API 670 Compliance
Fully compliant with API 670 standards, the assembly ensures accurate position, vibration, and Keyphasor measurements in automated industrial systems.

5. Flexible Installation and Intrinsically Safe Operation
The 3/4-14 NPT mounting, standoff adapter, and connector protector enable rapid deployment while supporting intrinsically safe operation in hazardous areas, enhancing automation reliability.
