MDR 53 - for oil, water, and air in single-pole design

Control pressure switch MDR 53

The MDR 53 pressure switch is suitable for use with oil, water, and air, in a single-pole design with 1 changeover contact, aluminum die-cast pressure connection, and CR membrane. The pressure switch is equipped with differential pressure adjustment as standard. Pressure adjustment is possible without tools! A handwheel allows for adjustment of the switching point and hysteresis, while the shutdown pressure is adjusted using the top handwheel (the spindle rotates with it). By selecting a pair of values for the switch-on and switch-off pressures, an intersection point is determined on the diagram.
