High-Resolution, High-Speed Sensing from Difficult Surfaces

The Selcom SLS5000 series of in-process non-contact sensors from LMI Technologies offers ultra high performance, even in hostile environments. Robust and with an extremely fast automatic light control circuit, this sensor measures on varying surfaces from matt topography to the shiny black materials of varying degrees of texture, colour and reflectivity often found in the tyre and rubber industries. It provides 16kHz data with real time control of laser intensity to provide accurate measurement data at a range of up to 1,250 mm and delivers resolutions down to 0.15 micron. The durability of the sensor housing allows usage in extreme temperature applications, such as thickness measurement of calendaring rubber at the extruder head. This provides users with a high performing sensor that can measure difficult target materials in hot and humid plant conditions.
