While most new users will get tremendous benefit with some basic racing data system sensors
below are some of our most popular Racing Data Acquisition Sensor options.

Low Pressure Aero SensorAir Box Pressure Sensor
"NEW" Low Air Pressure and Vacuum Sensor. The Perfect Sensor For Measuring Air Box Pressure for testing Aero Dynamics to Cooling System and Cooling and Brake Duct Air Pressures Our New Low Pressure and Vacuum Sensor is the perfect sensor to measure air pressures (or vaccuum) at any point of the racecar. Do you know if your NACA duct is in a high pressure area of the car? Do you know if your cold air intake (or air box) is really getting high pressure cold air to your engine's manifold? Is the air intake to your brake cooling ducts in the best spot? This sensor is used for PRACTICAL aerodynamic testing at the race track. This low pressure air sensor can measure both pressure and vacuum (for showing negative pressure areas), at many parts of the race car. The sensor can be placed right inside an air or cooling ducts, or a hose can be fitted over the nipple to allow remote sensing in areas where the sensor does not fit easily. The aero sensor outputs a voltage based on pressure changes which is then analyzed using our data acquisition software.  $199

Steering Angle SensorSteering Sensor Installed

Steering Position Sensor, Steering Angle Sensor
The steering sensor is a simple but very effective way to determine the handling of a race car.  Make a change and see if the change requires more (push) or less (loose) steering wheel movement through EVERY corner.  Steering Sensors can be used to see if steering wheel movement CAUSED a handling problem. Also helps to increase the feedback between the crew and the driver. It  is installed next to the steering shaft so an o-ring drive belt can rotate the sensor as the driver turns the wheel.  The steering sensor outputs a voltage based on steering angle which is then analyzed using our data acquisition software.  $119

Lever Throttle SensorRotary Throttle Sensor

Throttle Position, Throttle Angle Sensor (TPS) Used for measuring how far the throttle is open and for how long. Fast times are usually generated form the amount of time at or near maximum throttle opening. The sensor can be used to evaluate problems with the race vehicle as well as being used for driver analysis. $119 lever type pictured at far left; Rotary position (throttle shaft mount) also shown. For difficult mounting applications a string type throttle sensor is available.

Porsche Throttle SensorThrottle Sensor Installation

Throttle or Gas Pedal Plunger Position Sensor, Throttle Angle Sensor
This Throttle position sensor is called a plunger or linear throttle position sensor. The throttle sensor can be operated by the race car's throttle cable or racecar throttle lever pushing in on its plunger. The plunger itself is spring loaded in the extended position. Total travel of this throttle position sensor is 1.5". In the photo to the left, the sensor is installed in a Porsche race car, and is operated by the throttle cable. This sensor can also be used to measure as a brake pedal travel sensor, or other applications that require position. $109


String (Cable) Type Position Sensor (applications include Throttle, Steering, and Universal Position Sensing)  In applications where conventional sensors can be difficult to install, the String Type position sensor makes mounting a snap.  A small string (wire) is connected to a spring-loaded sensor inside the black housing.  Attach the string to an object that moves and the sensor will take care of the rest. For example it may be difficult to connect to the throttle linkage directly, but using a string allows the sensor to be mounted remotely and let the linkage pull the string (because of its ease of installation this is our most popular sensor for Throttle Position). It can also be used to wrap around rotating object like a twist throttle, or to wrap around a steering shaft to monitor steering position, or for many other components that require position sensing.  (note: this sensor is not recommended for suspension travel)

Sensor is available in 2.75 (most common for throttle), 4.75” or 10” of travel.   $219 


Throttle Sensors

Rotary Shock Sensors
Rotary Position Sensor, can be used as a Shock or SuspensionTravel Sensor, (bell crank shock applications) Throttle Position Sensor, or any device that requires a precision rotational measurement on the race car.
This sensor is a precision potentiometer that allows precise measurement of any rotary types sensor on the race car. This sensor can be custom order to read in 10 degree increments of rotation. This is very important when using this sensor as a shock or suspension travel sensor particularly when measuring shock velocities. It has a slotted end that allows for easy installation of any flat piece of metal to rotate the sensor. $259

EGT (Exhaust Gas Temperature) and/or
CHT (Cylinder Head Temperature)

Pressure Sensors Stainless Steel

AXLE, WHEEL, or DRIVE SHAFT Sensor  This sensor is used for measuring MPH as well as RPM of axle shafts, drive shaft, and input shafts.   This sensor is the one of the most important sensors that you can monitor, which is why it comes standard with our "Results" and "Professional" Data systems.  The sensor works by
sending a signal to the data logger when the magnet(s) passed by.   The software will
calculate MPH, speed through the corners, clutch slip and more with this sensor.  $60
additional special HI-GAUSS magnet $15.  (magnets are housed in a 1/4 Allen screw)

MPH sensor magnet

Speed Sensor Rotor AXLE, WHEEL, or BRAKE ROTOR Sensor  This sensor is used for measuring MPH and DOES NOT require an external magnet to measure wheel speed. (Wheel speed (MPH) is important for track mapping, braking distances, speed through the corners etc. This sensor can pickup up a signal from any metal bolt. The most common installation for the Speed sensor is to point the sensor at the bolt(s) that hold the Brake Rotor or Wheel Hub on. If you have a stock car, this is the most popluar installation on wide five, or 5 on 5 wheels. An alternative method on some racecars is to attach a bolt to the rotating hub and have it pass by the sensor. The software will calculate MPH, speed through the corners, distance around the race track and more with this sensor.  $75
Dual Wide Band 02 Lambda Sensors

While most of our system are designed to go directly the to the data logger,

we also sell gauge systems that can also be viewed without the data logger

This sensor should be installed into the exhaust system near the exhaust header, as the sensor must be 600°F to operate.  The sensor also has and internal 12V heater to insure accurate readings at low exhaust temperatures. Air Fuel Ratio Sensor with Heater $99  / Weld-In Bung $15.


02 Lambda Wide Band Sensor
Boost Sensor

Turbo Boost Sensor: This sensor allows for measurement of Turbo Boost Pressure as well as engine vacuum for precise monitoring of engine load and boost requirements.   The sensor automatically adjusts for atmospheric conditions and outputs a signal voltage in the positive or negative directions based on whether it senses engine vacuum, or manifold pressure (Boost).  $119

(Note: For Supercharger applications use our “Pressure Sensor”)

We carry a complete line of sensors, if you don’t see it, we can get it!  The sensors below are an example of some of our more elaborate sensors used for engineering.


RADAR Speed/MPH Sensor: Designed for engineering applications, this sensor measures relative motion.  Point the sensor at what you want to measure and speed will be measured. Either the sensor or the target may be moving (or both simultaneously).  The sensor is commonly used to measure the speed of a surface, such as the ground. 

Using RADAR technology, this is a non-contact sensor, meaning it measures only the true relative motion of the target.  For vehicle ground speed, wheel slip is no longer an issue.  This sensor can also be used for studying slip angles.  The sensor measures speeds from 1 to 300 MPH and is capable of tracking object accelerating at several G’s.  $2200.


IR Tire Temp SensorInfra Tire Temp Testing


Infra-Red Temperature Sensors: Now you can measure the temperature of components previously not practical with direct contact temperature measurements.  The most common application includes brake, engine and tire sensing.   Using 3 sensors (inside, center and outside of tire), combined with our data acquisition system and tire temps can be measure ON THE racetrack.   The image below shows a graph of Right Rear Tire Temps taken from a Lap of a Late Model Stock Car.  Only your imagination is the limitation of what can be measured.  Image at Left shows infra red pyrometer probes placed in a customer made bracket to measure 3 tire temperatures at once!
