Rotational-Speed Sensor | vSpeedBox
Highly accurate speed sensor with optional DAKKS calibration (DIN EN ISO/IEC 17025).
The vSpeedBox allows to measure speed without any tacho inputs and with a normal DC input. Inside the vSpeedBox, the input pulses coming from the LED-Sensor are used to measure the signal period with high accuracy based on 16 MHz time base. The speed values are calculated and converted to an speed-proportional analog DC output voltage, so they can be recorded by any data acquisition system with a DC input. Parallelly the impulse from the LED-Sensor are routed through to the TTL-Output, so data acquisitions having a special tacho input can be used as well. To guarantee a high accuracy, three speed ranges can be selected:
Advantages & Innovation

Procedure
For the selected speed range, the DC output has a resolution of 4000 steps. If the maximum speed is exceeded, the power LED starts blinking. The vSpeedBox system is build up of two components:
LED-Sensor Head
Controller
For the detection of the speed pulses we additionally offer customized optical sensors for
special test setups.
The speed ranges can be customized if required.
