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:
High accuracy tachometer with DC output
Speed ranges: 400 RPM, 4000 RPM, 40000 RPM
High precision analog voltage output (12 bit = 4096 values)
TTL output (pulse/rev)
DAKKS (ISO 17025) – calibration optional
Integration into existing measurement and monitoring systems
Optical sensor with M16 thread
Simple sensor assembly
Research and Development
RPM monitoring and control
Calibration of rotational speed sensors
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:
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.
