When the radiation exceeds trigger point, the electrical switching output is activated. The Hot Metal Detector electronic circuitry compensates for ambient temperature changes and component aging. Adjustment is therefore not necessary, thus providing higher operational safety and reliability.<o:p></o:p></span></p><p style="MARGIN-RIGHT: -0.5in" class="MsoNormal"><?xml:namespace prefix = v /><v:stroke joinstyle="miter"><v:formulas><v:f eqn="if lineDrawn pixelLineWidth 0"><v:f eqn="sum @0 1 0"><v:f eqn="sum 0 0 @1"><v:f eqn="prod @2 1 2"><v:f eqn="prod @3 21600 pixelWidth"><v:f eqn="prod @3 21600 pixelHeight"><v:f eqn="sum @0 0 1"><v:f eqn="prod @6 1 2"><v:f eqn="prod @7 21600 pixelWidth"><v:f eqn="sum @8 21600 0"><v:f eqn="prod @7 21600 pixelHeight"><v:path connecttype="rect" gradientshapeok="t" extrusionok="f"><o:lock aspectratio="t" ext="edit"><v:imagedata title="" src="file:///C:\Users\Buntya\AppData\Local\Temp\msohtmlclip1\01\clip_image001.png"><?xml:namespace prefix = w /><w:wrap type="square" side="right"><b><span style="font-family:';font-size:10;">Design Features</span></b><span style="font-family:';font-size:10;color:black;"><o:p></o:p></span></p><p style="TEXT-ALIGN: justify" class="MsoNormal"><span style="font-family:';font-size:9;">Hot Metal Detector are rugged infrared switches completely epoxy resin encapsulated in stainless steel housings.
