The principle of SPS-U speed measurement is very simple. By fixing the distance of the sensing point of the object, the measured object's arrival at the sensing point is timed. The speed of the measured object = fixed distance/time difference. The default fixed distance of SPS-U is 300mm, the upper and lower spacing between the transmitting and receiving points is 500mm by default, and the height of the foot is adjustable; the measurement range is 120km/h by default. All parameters can be customized according to customer needs.

        SPS-U provides customers with powerful functional interfaces and minimalist operation modes:

The equipment status is displayed in real time, which can be reset manually or by wireless remote control, and automatically enters the measurement mode;

Dual trigger output interface, can be used to trigger any device (such as ground camera);

Wired Ethernet and wireless WiFi (optional) function, which can be connected to the customer's local area network to realize the synchronous operation of software and hardware;

Use 9VDC-18VDC power supply, with power adapter, built-in battery function (optional), can also be connected to an external battery;

The remote connector or wireless (optional) mode is connected to a large-screen LED display, which can be hung on the wall, and the result can be seen at any time by looking up.

      In terms of measurement accuracy, SPS-U uses a special method to fix the sensing points to ensure precise measurement distance; in terms of timing accuracy, it uses high-speed response switches and high-frequency data processing methods to ensure precise timing effects. According to the default parameters, the theoretical measurement accuracy is as follows (indicating error):

Jebool also provides accessories such as speedometer cables, provides technical support when cooperating with other equipment, and can discuss and develop special functions and other requirements.
