InteliSENS® SLM-i4
SPEED & LENGTH MEASUREMENT
Proton Products InteliSENS® SLM-i4 Series non-contact, unidirectional speed and length gauges provide extremely accurate speed and length measurements for metals industry applications. They are available with extended stand-off distances and greater depth-of-field than the standard InteliSENS® SL Series gauges, which allows them to be used to measure very high-temperature objects such as in hot-rolling processes.
Applications requiring a precise cut-to-length process benefit from the non-slip and highly accurate laser measurement technique which reduces scrap increases uptime, and improves material yield by eliminating product “Give Away” or “Short Length” claims.
Focused on connectivity the SLM-i4 Smart Sensor with 32bit communications comes preloaded with Profibus, Profinet, and Ethernet Industrial Protocol for your PLC connection. Modbus, OPC-UA, RS232, RS485, and WiFi round out a wide range of digital communications for your Industry 4.0 Solution.
