Serpentine automatic trigger
The serpentine automatic trigger is mainly used to determine the time when the vehicle enters and exits the effective pile area in the serpentine test. The time to pass the effective pile area in the serpentine test is one of the main parameters, so the time point for the vehicle to enter and leave the effective pile area must be, Using automatic triggering can greatly improve the degree of testing and avoid human errors caused by manual triggering.
The automatic trigger is composed of a transmitting unit, a receiving unit and a wireless data transmission module. The infrared trigger principle is used to detect the entry and exit of the test vehicle. The trigger signal can be transmitted to the test host in real time through the wireless module. The test accuracy is high and the use is convenient.
●The trigger is fixed by a liftable tripod, which is convenient and quick to use
●energy-saving design, which can effectively save energy
●The trigger point is consistent and the trigger accuracy is high
●The beam has strong anti-interference ability and can be applied to various complex environments
●The digital tube displays the received signal strength, which is convenient and quick to debug
●The beam cut-off time is adjustable, which can select the appropriate beam cut-off time for any environment
