Honeywell Chadwick-Helmuth Mounting Bracket (8500C/Vibrex)
Overview
The Honeywell Chadwick-Helmuth mounting bracket is a structural accessory used with the 8500C and Vibrex analyzer kits to mount sensors, pick-ups and auxiliary equipment on the aircraft or in the workshop. The bracket is manufactured to the Chadwick-Helmuth design and is supplied as a verified spare for maintenance organisations that operate the analyzer family. It provides a rigid and repeatable mounting point, which is required for consistent vibration measurements on helicopter and fixed wing aircraft.
The bracket is used at the helicopter pick-up points defined by the Chadwick-Helmuth procedure and at the engine and propeller locations of fixed wing aircraft. The sensor is attached with the standard studs and clamps, and the bracket position defines the measuring axis for the analyzer. The same part is used in the workshop test fixture, where the analyzer is verified against the reference vibration source under identical mounting conditions for every calibration run. The spare is inspected before shipment.
Engineering and Design
A vibration measurement is only as repeatable as its mounting point, so the bracket is designed to hold the sensor firmly in place with a defined orientation relative to the measured axis. The bracket is used with the standard Chadwick-Helmuth sensor mounting hardware, including the studs and clamps that attach the pick-up to the airframe structure. Because the same bracket geometry is used across the analyzer family, a single spare supports the 8500C, 8500C Plus and Vibrex 2000 kits.
The bracket is inspected against the original Chadwick-Helmuth drawing before shipment, including the hole pattern, the mounting faces and the surface treatment. Maintenance crews keep the spare brackets in the analyzer kit so a damaged part can be replaced on site without delaying the balance run. The part is also used in workshop fixtures where the analyzer is checked against a reference vibration source.
The bracket is installed with the standard Chadwick-Helmuth mounting hardware and is positioned so the sensor axis is aligned with the measured direction. On helicopter airframes the bracket is attached to the prescribed pick-up point defined by the analyzer procedure, and on fixed wing aircraft it is used at the engine and propeller locations. The rigid connection prevents the resonance of the mounting structure from influencing the vibration reading, which is essential when the analyzer must resolve the rotor speed component from the total signal. In the workshop the bracket is used in the test fixture where the analyzer is checked against the reference vibration source, giving the same mounting conditions for every calibration run. The spare bracket is inspected against the original drawing before shipment, and the mounting faces and the hole pattern are verified with the gauge. Operators that perform on-site balance jobs carry the spare in the analyzer kit, so a damaged bracket is replaced without delaying the run. The part is compatible with the sensor mounting studs and clamps of the Chadwick-Helmuth family, which keeps the accessory set interchangeable across the 8500C and Vibrex instruments. The bracket completes the accessory set of the Chadwick-Helmuth analyzer family.
