The new series of LMI Selcom LBS non contact, laser-based industrial beam sensors feature better linearity and a longer range capability than equivalent sensors and offer more flexibility
The new series of LMI Selcom LBS non contact, laser-based industrial beam sensors is available now from Variohm Components, the UK's major supplier of position, weight, torque and force sensors.
Based on the shadow measurement principle, the new range is ideal for high-speed, non-stationary, hard-to-measure type applications in a broad variety of industries such as rubber, metalworking, aluminium, paper, textiles, plastics and many others where fast, accurate measurement is required.
The new products are low-cost and feature better linearity and a longer range capability than equivalent sensors and offer more flexibility.
The new units are available in 15 standard models and diaphragms.
The new Class II and optional Class IIIb LBS looks at the shadow it has created and does not rely on surface reflectivity for measurement.
They consist of an emitter and receiver which can be up to 3.3 feet (1 metre) apart without affecting accuracy.
The LSB sensor allows measurement independent of surface reflectivity or the position of the object in the beam and allows the sensor range to be amended to the application by simple adjustment of the diaphragm.
Measurement range varies from 0.02in to 1 inch (0.5mm to 25mm).
Accuracy is better than 0.5% at 10kHz and resolution is less than 0.1% of the measurement range.
The smallest detectable object is 0.001in (0.025mm).
Measurement frequency ranges from 1 to 10kHz.
The sensor can operate at temperature ranges from 0C to 50C.
Applications for the LBS sensor vary from measurement and control of diameters to width measurement, roller gap measurement, edge guiding of any rolled material such as textile, paper or foil, and detection of tears and ravels on almost any object.
