Single point gauging sensor for industry.

A single point industrial gauging sensor head has been designed for industrial applications with a limited work envelope requiring a faster sampling rate, higher resolution and higher speed profiles.

Based on the principle of laser triangulation, the Class IIIb and optional Class II and Class3R high speed PSD-based Selcom SLS 2401 has a visible laser diode for easy setup and safety, and a rugged design for harsh industrial environments. The IEC standard 60825-1, Class 3R allows a maximum laser power of 5 mW and assumes all Class 2 regulations as long as the wavelength is between 400-700 nm. This is said to eliminate the need for a laser safety officer and only requires basic training for all operators and maintenance personnel, according to the firm.

Applications include quality inspection and production control, in-line thickness measurement and profiling, width measurement, production line behavior versus speed, inspection of the finished product, plus a variety of other industrial applications.

The Selcom SLS 2401 sensor head has a stand-off distance of 50 mm (1.97") or 80 mm (3.15"), depending on the model selected, and a measuring range of 20 mm (0.8") or 50 mm (3.15"). Accuracy is [+ or -] 0.1 of the measurement range and band width (response) is 2 kHz.

The extremely small spot size of 0.055 mm (0.002") or 0.090 mm (0.004") is said to be ideal for use in confined, problematic applications.

The sensor's patented microprocessor-based fast light control circuit reacts in less than eight microseconds to compensate for and accurately measure varying surfaces without regard to ambient light changes, surface texture, color, the slope of the target, steep angles, silicone content, speed and more.
