Most fire protection gauges use a Bourdon tube, a curved metal tube that straightens slightly as pressure rises and moves the pointer across the dial. It sends no signal, but it is the inspector&#8217;s reference.<\/p>\n<p>A pressure switch is a control or supervisory device. A sensing element (bellows or diaphragm) moves an electrical contact when the set pressure is reached.

A 0\u2013300 psi gauge therefore suits a point whose normal working pressure does not exceed 150 psi.<\/p>\n<p>Rule two comes from the datasheet. For the 111.10SP, WIKA limits steady working pressure to 3\/4 of full scale and fluctuating pressure to 2\/3 of full scale. A 300 psi gauge is therefore good for 225 psi steady, or 200 psi where pressure fluctuates, as at pump discharges.<\/p>\n<p>Rule three is accuracy. \u00b13\/2\/3% of span (ASME B40.100 Grade B) means 3% in the first and last quarters of the dial and 2% in the middle half, so the most accurate readings sit mid-scale.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-11ffb16 elementor-widget elementor-widget-text-editor\" data-id=\"11ffb16\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2>WIKA 111.10SP: what the datasheet says<\/h2>\n<p>The <a href=\"\/en\/sa\/products\/wika-111-10sp-fire-sprinkler-pressure-gauge\/\">WIKA Type 111.10SP<\/a> is a Bourdon tube gauge built for fire sprinkler systems.
