MSE-V502
Velocity and length measurement gauge
The optical non-contact operating MSE-V502 is a modern velocity and length measurement gauge with a small separated head unit. The speed aquisition is realized using the spatial filter principle. It bases on the filtering effect of grid-like structures (grid modulation) implemented by a CCD-Sensor. The resulting frequency is detected by the device. The frequency is proportional to the velocity of the object being measured. The length can be otained by integration over the time. The object is illuminated by an integrated strong LED light source. The light is reflected to the CCD-Sensor according to the surface morphology (granularity). Almost every surface can be measured that way. A fast adaption to the surface condition of the object is guaranteed by built-in control loops adjusting the exposure time and the brightness. The head unit (MSE-V502-O) is connected to the evaluation unit (MSE-V502-E) with a wiring harness. According to the customer requirement the MSE-V502 can be equipped with several different industry interfaces or pulse outputs.
The small gauge head allows a space-saving installation in compact facilities in variou fields of the industry.
