SF-901 WINDYN DATA ACQUISITION SYSTEM

Overview

The SF-901 engine dynamometer was a workhorse in engine testing from the day it was released in 1982. Thousands of SF-901 engine dynos were produced and hundreds if not thousands are still in use today. The problem, the data acquisition system was designed in 1978 so it lacks features and capacity to adequately test modern engines and the majority of the electrical components required to service the data acquisition and control system are no longer available.
To help, we’ve developed a conversion kit to replace the dated SF-901 electronics with our latest WinDyn 3.2 data acquisition and control system. This upgrade allows SF-901 owners to keep the functional mechanical portion of their dynos and upgrade to the latest WinDyn data acquisition and control system making the dyno perform like new for less than half the cost.
The SF-ED-901 conversion package includes
  • New sensor box with 139 user configurable data channels
    • 16 channel thermocouple panel
    • 10 channel pressure panel
    • 2 pre-configured air fuel inputs (0-10v)
  • New control console to control tests, control engines and control the entire test cell
  • New computer system factory configured with WinDyn 3.2, two 22 in. LCD monitors and a color printer
  • New operator desk with integrated throttle handle and cable replaces the existing hydraulic throttle system
The current WinDyn system is ¼ the size and 100 times more powerful than the SF-901 giving you more data channels, better testing methods, higher resolution test data and a suite of modern testing tools to get the most out of your engines. WinDyn is easy to use, ready to run and ready to adapt to your needs.
Major benefits of the SF-ED-901 conversion package
  • Keep the functional mechanical portions of the SF-901, saving money
  • Data acquisition rates up to 2,500Hz - an increase of 100 times over the previous 20Hz rate for higher resolution data and finer analysis of engine performance
  • Automatic weather station improves test accuracy, repeatability and credibility
  • Improved engine control for excellent repeatability
  • Automated, ready to run test profiles with user defined sweep rates
  • Ability to integrate automatic throttle controllers or send a control out signal for fly-by-wire throttle
  • Advanced data analysis features
    • playback any saved test
    • plot or overlay up to 10 tests at a time on the graph
    • plot multiple channels at a time, for example plot air fuel ratio and torque
  • Migrate from an obsolete DOS computer to a modern Windows environment
    • Windows file structure - save virtually unlimited numbers of tests
    • Save data in folders organized by customer name or engine type including multiple subfolders
    • Email data files or export data into a customer data pack that customers can take with them
    • Analyze or store data on any Windows computer for better file back up
Onsite Installation and Training
The package includes three days of onsite installation and training by a SuperFlow service engineer. While onsite our engineer will:
  • Run baseline tests on the SF-901 for verification after the upgrade
  • Remove the SF-901 data acquisition and controls
  • Install the SF-ED-901 data acquisition and control system upgrade
  • Integrate existing sensors you wish to keep (temperature, pressure, air/fuel, etc.)
  • Configure the newly upgraded system for your application
  • Run comparison tests after the upgrade for verification
  • Spend two days training on the function and operation of the new system
Considering a used SF-901? Call us First!
If you are considering purchasing a used SF-901 give us a call first. We can tell you what to look out for, often tell you history on the machine and give you a quote for the SF-ED-901 conversion package that you can factor into what you want to offer on the used dyno.

FROUDE INVENTED THE WATER BRAKE DYNAMOMETERS

testingindonesia.com The Froude F Range Hydraulic dynamometers (also referred to as water brakes) have been designed to be compact, robust and to allow easy maintenance. Some of these models are available with a streamlined, fabricated base. This base is not only ultra durable due to the powder coating process, but also offers flexibility with water inlet/outlet placement and lifting eye locations. These engine dynos are fitted with two half couplings which, with the rotor, are oil injected onto the shaft. The standard machines run in grease lubricated rolling element bearings. The hydraulic dynamometer working compartment consists of special semi-circular shaped vanes cast into stainless steel rotor and stators. Water flowing in a toroidal vortex pattern around these vanes creates a torque reaction through the dynamometer casing which is resisted and measured by a precision load cell. The dynamometer load is controlled by a 'butterfly' water outlet valve, oper

The Froude AC dynamometer has been specifically designed for the testing of gasoline and diesel engines in R & D and Quality Audit applications.   Low inertia AC motor with standard speed ranges from 3,500 rpm to 10,000 rpm Standard torque hub measurement accuracy is +/-0.2% of the full rated torque of the dynamometer Speed is measured to an accuracy of +/- 1 rpm testingindonesia.com      SPESIFIKASI       Description The AC dynamometer is constructed using a low inertia AC motor especially designed for engine test applications mounted on a substantial fabricated baseframe. On foot mounted versions torque is measured using an in-line torque hub. For trunnion mounted machines a precision strain gauge load cell is used. As an option both versions can include an integrated jackshaft that provides additional overhung load capacity for the engine drive shaft.                 Froude AC       Dynamometer Heat gen

EDDY CURRENT ENGINE DYNAMOMETERS

Overview testingindonesia.com SuperFlow offers a broad selection of technologically advanced eddy current absorbers which are ideal for precise engine testing. Low minimum load capabilities allow testing of very small engines, or larger engines running at very light loads and high speeds. Heat is dissipated by cooling water flowing through the stationary portion of the absorber. Rotating water seals have been eliminated. Bearings are pre-lubricated and rated for 5,000 hours of operation between servicing. Standard commercial load cells measure reaction torque for either direction of rotation. The double-ended main shaft may be fitted with a starter motor or used for dual engine connection. Speed is measured by a 60-tooth gear and hall effect sensor. All SuperFlow dry gap eddy current absorbers can be interfaced with SuperFlow data acquisition and control systems for complete engine, dynamometer and throttle control. These systems integrate with personal computers running Supe
