Proton Products International has launched a new compact InteliSENS SL/SLR mini series of sensors. These laser Doppler speed sensors set new standards in accurate, reliable non-contact speed and length measurement of moving web products.

The InteliSENS SL/SLR mini series sensors are designed to replace cumbersome, inaccurate and high-wear contact-wheel measurement devices used in web production processes, whose accuracy can exceed 2%. These contacting sensors are prone to excessive measurement errors due to slippage, vibration, wear and dirt accumulation; resulting in product giveaway, production losses and non-conformance to specifications. The compact InteliSENS SL/SLR mini has what the company says is the smallest footprint on the market and provides a direct replacement for contact tachometers and wheel encoders. The installation is simple and the sensors’ compact size can also permit speed and length measurements from parts of the process that were previously unobtainable.

The InteliSENS SL/SLR mini series sensors are solid-state devices with no moving parts for maintenance-free operation. Their non-contact measurement technique provides an accuracy better than 0.05%, typically 0.02%. The motto is, “No marking, No slippage and No Moving parts.” They provide high accuracy and repeatability with CE-MID certified versions available. They come standard with intelligent, easy-to-integrate capabilities that feature a broad range of process interfaces. This includes Ethernet, RS-232 and WiFi communications as standard with optional PROFIBUS, PROFINET, DeviceNet, Industrial Protocol IP that can be substituted for the Ethernet communications interface.

The InteliSENS SL/SLR mini series is designed for use across a wide range of web industries including:
▪ Converting, Laminating & Coating
▪ Extrusion Sheet & Film
▪ Rubber & Vinyl Calendering
▪ Nonwovens and Textiles
