Differential Pressure Switch Is Suitable For Higher-Static Pressure Applications
Dwyer Instruments' series DX differential pressure switch features wetted materials of brass and flouroelastomer suitable for use with most gases and water based solutions. The switch can be used for low-differential pressure indication with set point on a decrease of pressure as low as 1 psid (0.07 bar).
Differential set point ranges are available from 2.5 to 75 psid (0.17 to 5.17 bar) on increasing differential pressure and 1.0 to 67 psid (0.07 to 4.62 bar) on decreasing differential pressure. The unit features a high-static pressure rating of 200 psig (13.8 bar) for higher static pressure applications. Standard is a weatherproof, UL type 4X, enclosure for dust laden, outdoor or wash-down installation environments.
Series DX incorporates an externally adjustable set point, integral mounting flange and a removable electrical terminal block for quick installation. The DX uses opposing diaphragms to sense the high and low pressure with a pivot mechanism that transfers the difference of the two pressures to the SPDT switch.
