InteliSENS® SLRM-i4

SPEED & LENGTH MEASUREMENT

The SLRM-i4 tracks very small speed and length product movements, forward and reverse, for hot and cold rolling applications.
Solid-state digital technology, with no moving parts, ensures rock-solid reliability.

The SLRM-i4 has accuracy better than ±0.05%. Testing of each SLM-i4 and SLRM-i4 includes temperature cycle tests before final QC testing. Each gauge has a unique UKAS calibration certificate. The SLRM-i4 connects easily to all standard control systems for fast commissioning and easy integration. The SLRM-i4 is bi-directional, with ‘zero speed’ capability and automatic direction detection.

Precise, high-resolution measurement
No moving parts: high reliability and low maintenance
Full integration with PLC, and metals gauging equipment
Industry 4.0 data communications
Permanent calibration, minimal maintenance
Rugged protection enclosures
Measures forward and reverse line movement, and zero speed (no motion)
Ultra-stable 780 nm laser diode (*XXX-780-i4 Series ONLY)
