More Information

Overview Manuals Specifications Application Protection Functions Precise Installation

Features:

  • Stainless steel construction provides superior corrosion resistance for offshore, chemical, and marine environments where aluminum housings would degrade.
  • CSA explosion-proof certification with CSA Type 4 enclosure rating ensures safe operation in hazardous areas with protection against water and dust ingress.
  • Flexible cable entry with three interchangeable grommets accommodates field cable diameters from 1/8 to 3/8 inches without additional adapters.
The 24701-28-05-15-026-03-02 is built from stainless steel specifically for applications where corrosion is a primary concern. In offshore platforms, salt spray can degrade aluminum housings within months, leading to compromised hazardous area seals and potential safety risks. Chemical plants expose equipment to aggressive vapors that corrode standard materials. Marine installations face constant humidity and salt exposure.

The 24701-28-05-15-026-03-02 carries CSA explosion-proof certification for Class I hazardous locations, making it suitable for refineries, chemical plants, and offshore facilities where explosive atmospheres may be present. Its CSA Type 4 enclosure rating provides verified protection against water and dust ingress—essential for outdoor installations, washdown areas, and locations exposed to rain or hose-directed cleaning.

The 24701-28-05-15-026-03-02 includes a cable seal grip with three interchangeable grommets, covering the most common cable diameters encountered in industrial wiring: 1/8-3/16 in, 1/4-5/16 in, and 5/16-3/8 in. This eliminates the need to source separate adapters or seal kits for different cable sizes, simplifying installation and reducing the risk of using the wrong grommet.

The 24701-28-05-15-026-03-02 Bently Nevada Proximity Probe Housing Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Gas Turbines: Monitoring bearing vibration and displacement near the exhaust end or combustion chamber of gas turbines.
  • High-Temperature Steam Turbines: Axial position monitoring in high-temperature areas such as high-pressure cylinders (HP cylinders).
  • Special Industrial Processes: Rotor monitoring inside high-temperature pumps, hot air blowers, or chemical reactors.
  • Dynamic Vibration Monitoring: Captures the radial motion of the shaft to diagnose imbalance, oil whirl, or axial friction.
  • Static Displacement Monitoring: Monitors the axial position of the rotor relative to the bearing to prevent serious stress trips.
  • OK Circuit Self-Diagnosis: In conjunction with the proximitor, the system continuously monitors cable integrity. If a probe is damaged, the cable is broken, or a connector is loose, the system immediately triggers a "Not OK" state to prevent false alarms caused by sensor malfunction.
  • Due to the larger linear range of the 16mm system (typically around 4mm), its standard linear center point is usually set at -10 VDC output.
  • During installation, a multimeter must be used to monitor the preamplifier's output voltage to ensure the probe remains in the linear region throughout the entire expected range of mechanical operation.
Description
The 24701-28-05-15-026-03-02 is a stainless steel housing designed for 3300 XL 8 mm probes in hazardous areas requiring corrosion resistance. Its 1.5 in standoff adapter positions the housing away from the machine casing, while 2.6 in probe penetration provides adequate reach for standard thickness casings. 

Built for intrinsically safe applications, the 24701-28-05-15-026-03-02 carries CSA explosion-proof certification and CSA Type 4 enclosure rating, protecting against water and dust ingress. It meets API 670 requirements for externally mounted probe housings, ensuring acceptance in petroleum industry installations. 

Installation of the 24701-28-05-15-026-03-02 is simplified by the included cable seal grip, which accommodates field cable diameters from 1/8 to 3/8 inches using three pre-sized grommets. The 0.5 m probe cable provides ample length to reach termination points without excess coiling. 

This housing solves the challenge of mounting proximity probes in corrosive hazardous areas where aluminum housings are unsuitable.
