Bidirectional Length Gauge - ÁSPEED-PRO

ÁSpeed Smartsensor

Non-contact direction detection - bidirectional measurement

Zero Speed measurement - stand-still detection

Offering non-contact direction detection and measuring starting from zero-speed with a typical measurement accuracy of +/- 0,05% /*2) the ÁSPEED-PRO is the ideal sensor to work in complex transport and conveying processes. Besides the sensor complies to the ÁSPEED-SMART seriec, with its processing unit integrated into the sensor head (154x94x39mm). Thus the gauge is the smallest bidirectional sensor in its class of high accuracy length and speed measurement devices with non-contact direction detection worldwide. ÁSPEED-PRO gives out directly length and speed data via RS 485/ RS 422 interface or pulses. All known industry bus standards as well as Ethernet are available optionally.
