Brake Dynamometer DAQ and Controller

3195.00 €*
4195.00€* (AWD)
(Prices do not include VAT)

New SP5-AWD DAQ version!

The SP-5 dyno controller provides all the necessary hardware and software controliing an engine test bed dynamometer, or rolling road dynamometers. The SP-5 is a fully digital PID based closed-loop speed controller. It is the perfect tool for engine performance testing, ECU calibration, endurance testing, emissions etc.

The new SP5-AWD version provides electronic synchronization between front and rear axles for AWD operation

It is also capable of controlling a 2-HUB dynamometer using each roller channel for each brake (right and left brakes)

Rolling Road Dyno

SP5 Can be used on several types of rolling road dynamometers:

  • Motorcycle (single roller)
  • Car, 1 axle, single roller per wheel (or long single roller)
  • Car, 1 axle, twin roller per wheel (brake is mounted on the front rollers)
  • Car, 2 axle, single or twin roller per wheel, but only one axle at once
  • AWD Car: 2 axle, both axles operating at once. NOTE: this option has an extra cost!
  • Other dynos based on rollers, with a maximum of 2 speed sensors

Engine Testbed Dyno

Part List for a complete Engine Testbed installation:

  • SP5 unit. It can work stand alone or with the computer.
  • Computer. Win98, ME, 2000, XP, Vista, Win7, Win8.1.
  • Hall Effect Sensor. Included with SP5.
  • Gear Tooth. Installed on the eddy current brake to read its speed. For example 8 teeth.
  • Load Cell. It depends on the engine, typical values are 500 kg for bike engines and 1000 kg for cars, but it should be calculated.
  • Eddy Current Brake. 192 volt rated, it size depends on the application.
  • Power supply: Sportdevices control module + SCR & diode pack.
  • Throttle Servo (optional). A high torque RC servo can be used to drive the throttle.
  • Ignition and Starter Relays. 12 volt relays to control the engine. Additional relays can be installed on the SP5 to control the fans on the room.
  • Fans / Turbines. Some type of fans or turbines are needed to next functions:
    • Feed the air intake with fresh air from outside the room (inner air gets hot quickly) this turbine should be very high power (>2 KW, or >5KW) and high speed to simulate on-track conditions, a variable speed driver is recommended + frequency to voltage converter to use the brake speed.
    • Exhaust extraction, the pipes should be made with iron or steel because the high temperature of exhaust gas.
    • Engine coolant, water should by couled by a fan, a car's fan or a truck's fan can be used with a thermostat to ensure the water will be at a right temperature.
    • Engine and exhaust pipes cooling, when runing on the track the exhaust pipes are being cooled as the vehicle runs, but when working on the dyno they may get too hot and can be damaged. Certaint exhaust pipes can not work at high temperatures (for example: titanium)
  • Variable speed driver. It is recommended for air-intake turbine.
  • Frequency to voltage converter. It converts the brake speed to a voltage for the variable speed driver. Our F-V converter has a programmable transfer curve to let the user to adapt the turbine speed to the brake speed as he needs. An air speed sensor is recommended.
