Series DS31 — differential pressure switches

• Pressure range: -1 to 6 bar • For non-corrosive gases and liquids • Continuously adjustable set point • Sturdy, accurate and with good repeatability Industrial applications in the following fields: water treatment, thermal engineering, heating and any industrial process This pressure switch consists of a chamber with two inlets, high and low pressure. The diaphragm is subjected to the two pressures being measured, which exert a force on each side of it. The resulting force moves the diaphragm, which changes the state of the microswitch. The switching point is adjusted with an external graduated handwheel coupled to the spring.
