Balancer/Analyzer 8500 C Plus (Obsolete)
The Honeywell Chadwick Helmuth 8500 C Plus Balancer/Analyzer performs helicopter rotor track & balance, fixed wing propeller track & balance, helicopter and fixed wing vibration surveys, and vibration analysis/trend analysis. This digital computer/FFT analyzer uses a bright, backlight display, integral printer, built-in help, and Smart Chart™ technology enabling anyone from the trainee to the experienced dynamics engineer to realize optimal maintenance solutions for all vibration-related maintenance tasks.
The Honeywell Chadwick Helmuth 8500 C Plus Balancer/Analyzer is Obsolete and no more manufactured.
The Easiest and Most Widely Used Airplane and Helicopter Rotor System Propeller Balancing Equipment in the World Today
The 8500C+ is the latest and most capable system in the long line of legendary Chadwick-Helmuth balancers and vibration analyzers. State-of-the-art digital technology together with proven Chadwick aircraft vibration knowledge and experience provides quick and easy identification and control of aircraft vibration problems before they become costly. Don’t put your maintenance and flight crews through hours of repeated aircraft starts and flights trying to smooth an aircraft; the 8500C+ will provide you the analysis and balance solutions quickly, safely, and in least number of flights possible.
The 8500C+ also includes rotor blade tracking by automatic Fastrak optical tracker or hand held Strobex. The Chadwick-Helmuth 8500C+ is used by more commercial and military users than any other smoothing and balancing system in the world.

Visual Blade Tracker “Strobex 135M-12” P/N 8620


It requires “Tip Targets” on the blade tip which are usually part of the Application Kit for V2K(+), Carry-On VXP and 8500C(+).
Observed Track & Lead/Lag data are either recorded on a tracking record sheet or entered in the 8500C(+) “Smart Chart” to be respected in the calculated Track & Balance adjustments.
Optical Blade Tracker “FasTrak” P/N 11800-3


When used with Carry-On VXP the Track & Lead/Lag data are collected simultaneously while measuring the dynamic balance.
For use at night, a Retro Reflective self-adhesive tape is used at the trailing edge of the rotor blades to reflect the emitted IR light of the IR LCD ring below the cover glass.
Portable Printer “DPU-414-M”


This line printer makes it comfortable for the user, to get printouts at the aircraft, without the need of a PC Printer in an office.
Its rechargeable battery allows printing even without supply power from the aircraft. The rechargeable battery is charged via the Acquisition Unit of the Carry-On VXP.
Vibration Sensors


High Temp. Accelerometer used for vibration test and analysis on turbine engines.
Accelerometer 4177B, P/N 4109 used for the legacy VIBREX System with Balancer 177M-6.
Azimuth Sensors


Photo Probe , P/N 10200-1 typically used as RPM and azimuth reference for dynamic balance measurement of tail rotors, drive shafts and blowers, with 8500C(+) and Carry-On VXP.
Photo Probe , P/N 12900 typically used as RPM and azimuth reference for dynamic balance measurement of tail rotors, drive shafts and blowers, with V2K(+)
Sensor Cables


Magnetic Pickup Cables, P/N 10808-X available in different lengths, used for V2K(+), Carry-On VXP and 8500C(+).
Photo Probe Cables, P/N 10185-X available in different lengths, used for V2K(+), Carry-On VXP and 8500C(+).
Azimuth Reflectors and Tip Targets


The Reflector Set P/N 3300 is applicable as Azimuth Reflectors for the Photo Probe P/N 10200-1 as well as for the Tip Targets 3428-2/-4.
The full selection of retro reflective material for use as Tip Targets with out bracket or as spare for Tip Targets is shown and described under “Details”.
Basic Sensor Brackets

The Photocell Bracket P/N 10423(-1) is used for installation of the Photo Probe , P/N 12900.
Aircraft specific Brackets for Accelerometer 4177B and Velocimeter 7310 are offered as part of Application Kits, if needed.
Application Kits

The required Application Accessory is quoted specifically for the various “Portable Systems” and aircraft/engine type.
Brackets and Interrupters


Interrupters are aircraft specific parts made of magnetic Stainless Steel which generates an RPM and azimuth reference when passing the Magnetic Pickup.
Brackets and Interrupters are available for many helicopter and fixed-wing aircrafts, as part of the Application Kit for “Zing® Test” Systems.
Adapter Cables


Breakout Cables are used for aircrafts which have a partly or complete hardwiring for DC Supply power and sensors of the “Zing® Test” Systems.
Application Software


The “Advanced Smart Charts” of the Carry-On VXP allow simple/quick data collection of Track & Balance of one or multiple regimes and calculate rotor adjustments for Track and/or Balance respecting current settings and rotor limits.
For 8500C(+) Chart Sets are provided in form of a 3.5” Floppy Disk, containing “Smart Charts” available for almost any helicopter and turboprop aircraft type as well as for some turbofan engines.
Precision Tab Tools (optional)


Precision Tab Tools are available for many different helicopter types from Honeywell, supplied with calibration plates and instructions and partly with a specific carrying case.
