An electronic pressure switch offers supplemental continuous output of either 4 to 20mA or 1 to 5 Vdc. The 805QS pressure switch is a cost effective, compact loop-powered design. Its rugged construction and three-year warranty makes for a low cost of ownership. The 805QS is ideal for hazardous locations and hostile environments where space is limited. It supports applications where engineers prefer low-cost, discrete, and continuous output monitoring. The switch’s set points and supplemental continuous output zero and span points are field adjustable by an optional calibration kit.
“Our window-type operation closes when the pressure is between minimum and maximum set points and will open when the pressure is outside of this range,” said SOR Product Manager Lance Cooper. When the unit loses its power source or stops working, all three switch actions change to the open state indicating a fault condition,” said Cooper. SOR Inc. has a registered quality system to ISO 9001:2008.
