Rotational speed sensor vSpeedBox

optical

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 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 Applications & Integrations Test benches Research and Development Machine diagnostics RPM monitoring and control Serial testing Quality control Calibration of rotational speed sensors
