Bently Nevada 19048-00-60-05-02 11mm Eddy-Current Proximity Probe Product Specification

19048-00-60-05-02 is an original US-manufactured 11mm tip diameter non-contact eddy-current proximity probe belonging to Bently Nevada classic 7200-series transducer system, specifically matched with 19049-04 standalone proximitor driver unit to build a complete displacement measurement loop for rotary machinery condition monitoring. The five-segment model code defines core configuration parameters: 19048 stands for base probe series, 00 refers to standard threaded body structure, 60 means total integrated cable length of 60 inches (approx 1.52 meters), 05 denotes 5/8-18 UNF standard mounting thread specification, and 02 represents miniature coaxial straight plug terminal at cable end for quick connection with extension cable or proximitor input port. Manufactured with high-grade stainless steel probe housing and anti-aging shielded silicone cable plus braided metal shielding layer, this probe converts the clearance variation between probe tip and rotating metal target into impedance change, which is further converted into standardized linear negative DC signal by paired proximitor, then transmitted to 7200-series rack monitor cards including 19156-01C and 19195BH for vibration, axial displacement monitoring and safety interlock control. It is widely deployed in thermal power, petrochemical, metallurgy and large pump industries for long-term continuous online monitoring of steam turbines, centrifugal compressors, induced draft fans and high-speed rotary equipment, serving as original replacement spare part for legacy TSI system maintenance and on-site renovation projects worldwide.

Description

Bently Nevada 19048-00-60-05-02 11mm Eddy-Current Proximity Probe Product Specification

1. General Product Overview

2. Application Scope

Working together with matched extension cable and 19049-04 proximitor, this proximity probe forms full non-contact measurement chain targeting core mechanical parameters of rotating equipment, mainly including radial shaft vibration value, static bearing shaft clearance, axial thrust position and rotor eccentricity; when combined with Keyphasor speed pickup accessory, it can also assist rotational speed and rotor phase collection for system calibration. Different from contact-type displacement transducers, eddy-current measuring principle eliminates physical friction and abrasion between sensing part and rotating shaft, making the product fit for uninterrupted 24-hour operation under heavy-load continuous production environment. After signal conversion via proximitor, the standard analog output can be accessed to local site indicators, DCS and PLC acquisition modules to realize real-time equipment health tracking and over-limit alarm plus emergency trip protection, effectively avoiding unplanned unit shutdown caused by abnormal shaft movement or bearing failure.

3. Detailed Electrical Performance Parameters

3.1 System Calibration Standard

The complete probe-proximitor assembly is factory pre-calibrated based on AISI4140 standard alloy steel target material with fixed nominal sensitivity of 7.87V per millimeter (200mV per mil), maintaining stable linear measurement within the rated effective clearance range from 0.25mm up to 4.5mm. The internal coil winding of probe tip adopts vacuum encapsulation process to guarantee consistent inductance characteristics and avoid measurement drift triggered by temperature fluctuation or mechanical vibration. The built-in double-layer metal shielding on outer cable effectively restrains electromagnetic interference generated by surrounding high-voltage cabinets and variable frequency drives to secure stable measuring precision under complex industrial electromagnetic field.

3.2 Electrical Matching Requirement

Designed exclusively for -24VDC nominal powered 19049-04 proximitor driver; the whole measurement loop supports total maximum system cable length combination up to 5 meters when adding field extension cable on the basis of built-in 60-inch cable of this probe, exceeding specified total length will cause sensitivity deviation and linearity failure of measurement system. Internal fine copper core wire structure features excellent anti-breakage performance to reduce open-circuit fault probability during long-term equipment vibration operation.

3.3 Built-in Fault Feedback Mechanism

Cooperating with paired proximitor, the probe can feed abnormal impedance signal to driver once core wire open-circuit, cable insulation short-circuit or probe-target clearance beyond calibrated linear range occurs; the proximitor will output deviated offset voltage to remind maintenance personnel of loop fault without extra professional testing instruments for quick troubleshooting.

4. Mechanical Structure & Environmental Specification

4.1 Mechanical Dimension & Mounting Feature

Equipped with 11mm sensing tip diameter and 5/8-18 UNF standard external thread body for threaded locking installation on bearing housing or customized mounting bracket, no additional fixing accessory required for field assembly. Total factory pre-attached cable length is 60 inches (1.52m), cable outer layer is resistant to oil, high temperature and chemical corrosion; terminal end is fitted with straight miniature coaxial connector matching standard Bently extension cable socket. Whole single probe net weight is around 0.12kg, compact body layout fits narrow installation space of various bearing pedestals and equipment casings. All solder joints between probe body and cable core adopt anti-vibration sealed welding craftsmanship to resist periodic vibration from adjacent running equipment.

4.2 Ambient Working Limits

Rated continuous operating temperature of probe sensing head ranges from -55°C to +120°C, applicable for high-temperature bearing box and low-temperature outdoor auxiliary equipment installation; storage and transportation temperature spans from -60°C to +130°C to adapt cross-region spare logistics and long-term warehouse inventory management. Allowable applicable relative humidity is controlled within 5%~95% non-condensing condition to prevent internal coil short-circuit caused by dew and cabinet dampness; the probe can bear moderate oil mist and weak corrosive gas environment inside equipment compartment, forbidden for long-term full immersion in liquid without customized protective sleeve.

5. Core Product Advantages

First, unified factory fixed sensitivity calibration ensures interchangeability with all standard 19049-04 proximitor and 7200-series monitor modules, greatly simplifying spare replacement and on-site system maintenance work without secondary field calibration after installation. Second, high-temperature resistant cable and stainless steel probe body expand applicable scenarios including high-heat turbine side and high-humidity chemical plant production area. Third, integrated pre-set fixed-length cable eliminates field wiring cutting and termination operation, lowering construction error probability and installation period for field technicians. Fourth, multi-layer shielding and sealed encapsulation structure reduce fault rate from field environmental interference and mechanical damage, effectively cutting later user maintenance and spare procurement expenditure.

6. Quality Standard and Warranty Clause

19048-00-60-05-02 proximity probe is authentic US-originated product complying with Bently Nevada internal factory quality inspection standard and relevant international industrial electrical safety certification for global automation market supply. When installed and operated strictly within specified electrical, mechanical and environmental parameters without artificial physical damage, cable random cutting or improper over-limit installation, the product enjoys standard twelve-month limited factory warranty against inherent original manufacturing defects calculated from formal delivery date of goods.
