Using high accuracy multi-constellation GNSS receivers, the speed sensors track GLONASS, Galileo and/or BeiDou satellites in addition to GPS, which improves the quality of measurements in areas of poor satellite visibility.
Selectable RS232 modes that include NMEA output of speed, position and time, or connection to VBOX Test Suite.
Data output is via CAN Bus, offering easy integration with data loggers and testing applications. Available channels are position, velocity, distance, time, heading, height, vertical velocity, lat/long acceleration, trigger to zero distance, trigger time, trigger speed, and radius of turn.
When connected to a laptop or PC (via serial) that runs our free VBOX Test Suite analysis software, you can monitor the test data from your vehicle, in real-time.
To facilitate unit configuration, the VBOX Speed Sensor has an OLED display and four membrane buttons on the front panel.
The aluminium enclosure is IP 67 rated, meaning it is protected against dust and water, and can be used in harsh environments.
All speed sensors are shipping with an ISO/IEC: 17025:2017 calibration certificate and can be calibration in-house.
Whether you're conducting brake testing, performance assessments, or lap timing, our Speed Sensors are the ultimate choice for non-contact measurement. Operating within a broad voltage range of 7 V to 30 V whilst consuming low current, they are a perfect fit for automotive testing, motorsport endeavors, marine applications, and telematics solutions.
Measuring a mere 9-14 cm in length and housed in a rugged, water-resistant enclosure, our units are incredibly easy to install and transport. You have a choice of two variants, depending on the update rate and accuracy you require.
VBOX 3iS, our speed sensor with inertial and wheel speed integration, significantly improves the accuracy of the speed and position data by combining wheel speed information from the vehicle’s CAN bus with GNSS and inertial data. In areas where there is no view of the sky at all, inertial sensors and wheel speeds can fill in the gaps for periods of up to five minutes. Additionally, the internal, high-grade IMU offers precise measurements of pitch, roll and yaw.
VBOX Speed Sensor measures the following parameters at 25 or 100 samples per second.
Add-Ons and Accessories
The MFD Touch is the perfect accessory to monitor one or more parameters during the test. Up to six GNSS/CAN-derived data parameters can be displayed simultaneously, and performance test results can be calculated and presented live from the vehicle.
The VBOX Brake Pedal Trigger (RLVBACS004) allows precise measurement of brake pedal application during braking. The exact time is captured and recorded by the VBOX at a high sampling rate.
* Specifications will vary depending on the number of satellites used, obstructions, satellite geometry (PDOP), multipath effects, and atmospheric conditions. Accuracies are stated to 95% CEP, meaning that 95% of the time the position readings will fall within a circle of the stated radius.
* Specifications will vary depending on the number of satellites used, obstructions, satellite geometry (PDOP), multipath effects, and atmospheric conditions. For maximum system accuracy, always follow best practices for GNSS data collection.
