Hawe pressure switches (DG & DT series) close or open electrical contacts when under pressure. They are used to issue an electrical switching command or signal for further operations when a predefined pressure value is reached…
Different versions (with pressure setting on an adjusting knob, main and secondary switch, screw-on pressure switch) enable their use in a wide range of applications. A design-related difference (hysteresis) of 8… 20% is to be expected between the upper and lower switching point in piston-type pressure switches.
In contrast to this, the type DG5E and DG6 electronic pressure switches provide the option to select two independent pressure switching points and/or program or adjust the hysteresis. Type DT is an analogous pressure sensor
Hawe DG series pressure switches are available in sizes: 1, 3, 5E, 6 and 8 and DT series are available in sizes: DT11 and 2.
