Honeywell Chadwick-Helmuth Mounting Bracket (8500C/Vibrex)

Name: Honeywell Chadwick-Helmuth Mounting Bracket
Brand: Honeywell

Description

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.

Why Seven Star LLC

Seven Star LLC supplies Chadwick-Helmuth analyzer accessories, including mounting brackets, to aviation maintenance organisations across Oman and the GCC. Every part number is checked against the original description before your order is confirmed, and our team helps you match the bracket to your analyzer kit. Because mounting brackets are typically specific to both the analyzer model, whether that is the 8500C or the Vibrex, and the airframe it is being fitted to, we confirm both details before shipment, since a bracket that fits the analyzer housing correctly but was designed for a different aircraft mounting point will not secure properly during a track and balance procedure.

For MRO facilities managing accessory inventory across multiple analyzer kits and helicopter types, we help plan bracket spares around your actual fleet composition rather than a generic inventory list, since a facility supporting several airframes may need distinct bracket variants for what looks like the same analyzer accessory category. If you are unsure which specific bracket variant your kit requires, send us the analyzer serial number and aircraft type, and we will confirm the correct part before you place an order, so the bracket arrives ready to install rather than requiring a return and reorder once it’s found not to fit during a scheduled hangar visit that has no time to spare for the wrong part showing up on the workbench at exactly the wrong moment during a busy maintenance day.

About brand

Chadwick-Helmuth is the name behind the rotor track and balance equipment used on helicopters and propeller aircraft: balancers, vibration analyzers and the tracking accessories that go with them. Units carry either Chadwick-Helmuth or Honeywell on the nameplate. Seven Star LLC, an independent supplier in Oman, lists the 8500C and 8500C Plus balancer and analyzer, Vibrex accessories and related parts.

Chadwick-Helmuth equipment listed here

The listings fall into two groups. The first is the instruments themselves: the 8500C rotor track and balance analyzer and the 8500C Plus balancer. A Model 11/11A/11B unit is also listed; reseller literature shows this designation both for a balancer and for the calibrator units used to check Vibrex and Strobex equipment, so the part number must be confirmed. The second is what a maintenance crew needs around them:

Photocell system for the 8500C
Printer assembly for the 8500C and Vibrex
Mounting brackets for the 8500C and Vibrex
Protractor used as a blade tracking accessory

A balancing kit is assembled per aircraft type, so brackets, cables and sensors are selected for the airframe as well as for the analyzer.

Where the equipment is used

Rotor track and balance is routine maintenance for helicopter operators: measuring vibration at the rotor frequency, checking blade track, and adjusting weights, pitch links or tabs until the readings fall within the maintenance manual limits. Propeller balancing on fixed wing aircraft follows the same principle.

Ordering Chadwick-Helmuth parts: what we need

Send the part number and description from the kit list or the label, the analyzer model (8500C, 8500C Plus, Vibrex or Model 11 series) and its serial number. Name the aircraft type the kit is used on, since brackets and cables are airframe specific. If the part number has been superseded, we ask for the manufacturer's current replacement and show you both numbers before you decide.

Fixed gas and flame detection takes up the largest share of our Honeywell listing: Searchline Excel open path detectors, Sensepoint XCD and XRL point detectors, the XNX transmitter and the FS24X Plus flame detector. Honeywell, which dates from 1906 and is headquartered in Charlotte, USA, also makes SmartLine pressure transmitters and VersaFlow flowmeters for process plants.

Seven Star LLC is an independent supplier of Honeywell gas detectors, replacement sensors, transmitters and controller parts for sites in Oman and the GCC.

Open path infrared detection is represented by the Searchline Excel and the newer Searchline Excel Plus. Point detection includes the Sensepoint XCD in flammable and toxic versions, for example the SPXCDALMG1 hydrogen detector, the Sensepoint XRL and the XNX universal transmitter. The FS24X Plus is a triple infrared flame detector. Replacement cells such as the SR-X2V oxygen sensor and the SR-W-MP75C MICROpeL combustible sensor are also listed. Process instruments include SmartLine STG700 and STG800 gauge pressure transmitters, the STR82D remote seal transmitter and the VersaFlow Coriolis mass flow meter. Recorder consumables such as chart pens are also sourced.

Where Honeywell detectors and transmitters are used

Gas and flame detectors guard wellheads, compressor stations, tank farms, loading bays, process units and utility buildings, and report to the fire and gas system. Open path units watch plant boundaries and long pipe racks. SmartLine transmitters and VersaFlow meters measure pressure and flow in refining, gas processing, chemicals and power.

Ordering Honeywell gas detection parts: what we need

Send the full part number from the label, such as SPXCDALMG1 or 02104-N-XSSA, and the serial number. For gas detectors state the target gas and measuring span, housing material, cable entry thread, output (4-20 mA, relays, Modbus) and the approval required. For replacement sensors name the detector model they go into. For SmartLine transmitters send the complete model selection string.
