Mini SLR

Bidirectional speed/length measurement

The SLR mini series gauges offer speed and length measurement for bidirectional production lines. The gauge senses the direction of motion and will automatically increment or decrement the length accordingly. SLR mini gauges are thus suitable for production lines that undergo direction reversals or stationary (zero speed) periods.

The SLR mini series of laser speed and length gauges provide highly-accurate, non-contact speed and length measurement. Compared to traditional contact wheel encoders, SLR mini non-contact speed and length gauges offer the following advantages:

Capable of measurement at much higher speeds and accelerations
No slippage
Greater accuracy
No wear or damage to the measured object
Solid state design results in higher reliability and MTBF

RS-232 and Ethernet communication interfaces are installed as standard for straightforward connection to computers or PLCs. One optional industrial standard communication interface (PROFIBUS, EtherNet/IP or DeviceNET; replaces the standard Ethernet interface) may also be installed in the gauge.

User configurable digital inputs are provided as standard to reset gauge measurements and trigger printing. User configurable digital outputs are provided as standard to signal gauge status and pre-set length reached.
