REMOTE HIGH SPEED MODEL 9207 Hot Product Sensor (Background suppressed)

UTILISING OPTIC LEADS & SEPARATE LENSES Optic leads withstand 400°C Quartz Rod lens option withstands 1000°C Highly precise viewing angles Unique “combined” Air Purge & Cooling Interchangeable Remote Lenses 1°, 4°,7°, & 1⁄2° x 25° F.O.V. Quartz Rod Lens 1° F.O.V, 1000°C spec. (for under the line mounting)

Robust sensor purpose built to meet the higher speed detection requirements within the modern Steel Mill. Armoured optic lead allows remote lenses to be installed close to the process line in high ambients, whilst allowing the controller to be mounted in an accessible area. This sensor provides two types of output. In addition to the normal latched output indicating presence of hot product, a high speed 0.5 milli.sec pulsed output is initiated by the passing of the hot products leading edge. Both PNP transistor and reed relay outputs are provided according to the model selected.

Precise Slit F.O.V 0.5° x 25° lens

It is important to note that the pulsed output response time is virtually independent of the hot products temperature. In addition, background infrared is filtered.

An adjustable latching timer is provided on the pulse output to extenuate the leading edge signal and accommodate blackspots. A variety of remote lenses are available. For mounting above the line, the 0.5º x 25º lens is recommended for highest accuracy. Alternatively, for mounting close under the line, the quartz lens should be used. A supplementary analogue output assists in alignment off a small light source as well as providing early indication of lens contamination.
