RET Automation is offering the new Kübler linear measurement system. This system is a high-resolution linear encoder that allows measurement of linear position or speed without contact between the sensor head and scale. The system is available with a moulded eurofast quick disconnect, which offers the customer higher performance, lower cost and a faster and more reliable installation.
The linear measurement system senses movement via a magnetic scale and a separate sensor head. The scale, which has equally spaced north and south magnetic poles, is bonded to a stainless steel band. The sensor head provides quadrature pulses from which speed, position and direction of travel can be determined. This system allows a customer to specify a resolution of either 20 or 100 µm for a given application.
The system is IP 67 rated; consequently, it is completely immune to contaminants such as dust and liquids. The scale comes with a stainless steel covering that can be used for protection against metal shavings, filings etc, and is available in lengths up to 90 m. The non-contact nature of the encoder results in extended life when compared to traditional mechanical systems.
Easy to install, the system can be used to retrofit current applications where speed and position values are sent to a display or used as an input to a controller. This technology provides a great economical alternative to optically based devices.
