Non-contact Length Gauge - µSPEED-classic - MID 2004/22/EG standard
Non-contact length measurement - Laser doppler technology
length measurement system processing unit and display
The µSPEED-classic consists of a small sensor head (154x94x39mm) and a processing unit. Both components are connected by a pluggable cable. The processing unit includes a display with two lines for showing the actual length and speed as well as signal qualiy or other parameters. The sensor system, which is accredited by the national German metrological institution (PTB) since 1999 (since October 2006 the certification is accepted EU qualification approval, since 2008 also according to MID (measurment instruments directive) 2004/22/EC standard), is unique regarding its size, reliability, ease of use, lifetime, various control functions and accessories. The system is used as a portable gauge for calibration of machine encoders but also for cut-to-length control to equip older machines with so far manual driven cutting devices. A RS232 printer can be connected directly to the processing unit for printing out customer specific labels or measurement protocols. µSPEED-classic is available as 110VDC and 230VDC version and gives out direct length and speed data via RS232 interfaces or via analogue or pulse output. The system can furthermore process control signals via opto isolated in- and output interfaces.
