DWYER <a href=\"https:\/\/intl.dwyer-inst.com\/Product\/Pressure\/DifferentialPressure\/Gage-Switches-Dial\/SeriesA3000?Query=A3000\">Series A3000<\/a> Photohelic Pressure Switch\/Gage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Two phototransistor actuated, DPDT relays are included for low\/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face.<\/p>\n<p>&nbsp;<\/p>\n<section id=\"specs\" class=\"ui-tabs-panel ui-widget-content ui-corner-bottom\" role=\"tabpanel\" aria-labelledby=\"ui-id-3\" aria-expanded=\"true\" aria-hidden=\"false\">\n<h1 class=\"tab-heading\">Specifications<\/h1>\n<p><b>GAGE SPECIFICATIONS<\/b><\/p>\n<ul>\n<li>Service: Air and non-combustible, compatible gases.<\/li>\n<li>Wetted Materials: Consult Factory.<\/li>\n<li>Accuracy: \u00b12% of FS at 70\u00b0F (21.1\u00b0C). \u00b13% on -0 and \u00b14% on -00 models.<\/li>\n<li>Pressure Limits: -20&#8243; Hg. to 25 psig (-0.677 to 1.72 bar).
