Hall effect sensors, in combination with a tone wheel, are considered the most accurate and reliable method to get RPM of a brake, engine, or just about anything that rotates.  These hall effect sensors will work with just about any dyno data system, and are guaranteed to work with the data systems from Precision DynoTech.

• 4mm sensing distance
• 12x1mm threaded body

Our DC-3 data acquisition system takes what the DC-1 and DC-2 already have, and adds to it!  Notable features include a stepper output for connecting to a stepper driver and motor for controlling a load valve.

An aux output is also capable of PWM output for controlling an eddy current brake power supply.

Features include the following:

• 2 RPM inputs
  • Can use tachometer signals from points ignition systems, electronic ignition, IR photo sensors, or hall effect sensors
• 2 Load Cell Inputs
  • For use with a wheatstone bridge type load cell (the most common S beam load cells)
  • 24 bit ADC for high resolution data
• 4 analog inputs
  • Use for pressure sensors, AFR signals, throttle position, raw voltages, and more
• 4 K-Type Thermocouple Inputs
• CAN Bus
• Stepper Output
• AUX 0-5v output
• Built-In Weather Station:  Air temperature, Barometric Pressure, Humidity
• Color coded connectors for easy installation
• Durable Anodized Aluminum Case
• USB-C connection to interface with a PC running Windows.
• Includes Precision DynoTech “RevBench” Software
  • Correction factor calculations based on user input atmosphere settings
    • STP, SAEJ1349, or Uncorrected
  • Complete data logging of all channels
    • Can start manual logging (user start and stop)
    • Automatic logging based on starting and ending RPM values
  • Data viewer to view all channels
    • View data channels over time and over RPM
  • Printing of saved tests
    • Includes max power, torque, corrections, and user-defined notes

Our DC-2 data acquisition system is perfect for upgrading older and simpler dyno installations, such as those who want to upgrade from an old Stuska analog gauge or similar.  We know there are plenty of setups that don’t need all the bells and whistles like electronic brake control and excessive amounts of data channels, so that’s why we made this data system!

Whe compared to the DC-1 unit, the DC-2 adds 2 Thermocouple inputs and a built-weather station.

Features include the following:

• 1 RPM input
  • Can use tachometer signals from points ignition systems, electronic ignition, IR photo sensors, or hall effect sensors
• 1 Load Cell Input
  • For use with a wheatstone bridge type load cell (the most common S beam load cells)
  • 24 bit ADC for high resolution data
• 2 analog inputs
  • Use for pressure sensors, AFR signals, throttle position, raw voltages, and more
• 2 K-Type Thermocouple Inputs
• Built-In Weather Station:  Air temperature, Barometric Pressure, Humidity
• Color coded connectors for easy installation
• Durable Anodized Aluminum Case
• USB-C connection to interface with a PC running Windows.
• Includes Precision DynoTech “RevBench” Software

    • Can start manual logging (user start and stop)
    • Automatic logging based on starting and ending RPM values
  • Data viewer to view all channels
    • View data channels over time and over RPM
  • Printing of saved tests
    • Includes max power, torque, corrections, and user-defined notes

Includes:

• Clamp-on inductive pickup.
• RPM Amplifier and Filter
• 6 Position DIP switch for easy configuration
  • Configure a max RPM for your use, ignoring any errant signals that would otherwise cause a false signal.
  • Push-Pull or Open Drain output signal.
  • Auto-level detect based on the input signal strength
• Terminal block with optional inputs (if the clamp pickup is not used)

For use with external coil ignition systems.  Simply hook up the inductive clamp onto a spark plug wire, and hook up the output of the included filter circuity to an input on a Precison DynoTech data acquisition unit.  The attached filter deals with the very noisy spark plug signal and creates a clean and useable signal for many types of data systems.  This unit can be used with a variety of data systems, but Precision DynoTech cannot guarantee compatibility with all systems.
