JUMO 380641 Druck- und Differenzdruckschalter

The differential pressure monitor of type 4 ADS-82 is suitable to switch a current circuit ON, OFF or change it over, when the actual pressure value changes in relation to the setpoint value. The setpoint value (switching point) is manually set at a setting dial with scale. When the setpoint value is exceeded or fallen below, the current circuit is switched ON, OFF or is changed over. The differential pressure in the pressure chamber uses a membrane to counteract the force of the adjustment spring applied on the micro-switch. As over- and underpressure switches, the bottom section and the membrane with intermediate disc form the pressure chamber. As differential pressure switches, the bottom section and a second membrane with the intermediate disc form the two pressure chambers. For installation purposes, an additional air conditioning set can be ordered consisting of two hose connections, six self-tapping screws, two extension tubes, one drilling template and one plastic mounting bracket.
