Powerful due to optimum functionality The ASCOspeed 5500 is a powerful speed sensor which has been focused on applications in the metal industries. It operates according to the signal phasing groupe method and is therefore a further development within the proven spatial frequency filter technology. Thereby the moved material surface and measured by means of the precise grid structure of the detector and converted into an electrical frequency which is proportional to the speed of the object. A strong base due to many years of experience The spatial frequency filter method has been known for more then 40 years. Commonly model described as the “picket fence effect”, the flashing frequency is proportional to the speed of a moving light source behind the “pickets”. The “picket spacing” as a sensitive silicon grid and associated with more than 15 years of practical experience mark the outstanding features of this new powerful generation of speed and length measure equipment. Ease of use due to non-hazardous LED light source A high-performance LED is used as the light source. The back-scattered light from the passing object surface strikes the detector via a lens which generates the measurement signal. LEDs are on a par with semiconductor lasers as regards service life. However, with the LED Class 1, they represent a clearly reduced potential hazard as compared with the known Laser Doppler Velocimeters (LDV) principle.

adapted hardware State-of-the-art signal processing structures ensure that each change in the material speed is measured precisely. This is provided by extremely fast hardware which is able to register, check and compress the current speed values in the microseconds range up to maximum material speeds of 3000 m/min. It is only in this way that maximum precision can be realised for acceleration processes. The sensor also provides a reliable speed signal for the minimal averaging and output time of 0.5 milliseconds. Always one step ahead Conventional mechanical systems can be replaced without problems by the ASCOspeed 5500. The device has free scaleable quadrature pulse output channels and can therefore be used as an alternative to rotary shaft encoders. The synchronous operation provides significant benefits for the measurement of differential speeds such as for mass flow control or skin pass level control. Using trigger pulse from the controller, several hardware-controlled measuring process devices can operate exactly synchronously and in this way provide more precise results in acceleration phases. The master / Slave operation of two autonomous ASCOspeed gauges now makes possible the output of differential speed without additional PLC using internal calculation functions in the Master gauge. The interconnection of several devices in inspection lines simplifies the transmission of the speed information. Flexibility and compactness due to integrated design The compact design combines sensor and controller in one robust case and thus guarantees use in many different systems without problems. The device operates autonomously, has low power consumption and thus only needs a 24 VDC power supply. Internal temperature monitoring makes possible the integration in the controller of climatised applications and thus increases the operational reliability. Standardised interfaces open up many possibilities for the user in the automation of process lines.
