Description for Hawe Dg 34-300 Pressure Switches
Product DescriptionOBSOLETE - Limited inventory, no more will be manufacturedPressure Range: 100-500 BarDesign: Spring loaded piston type pressure switch, zero leakageTemperature: Ambient: approx. -40...+80å¡CPressure fluid: Hydraulic fluid acc. to DIN 51524Viscosity range: min. approx. 4; max. approx. 1500 mm2/secOptimal operation range: approx. 10...500 mm2/secProduct InformationThey 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.Electro-hydraulic pressure switches are devices which close or open electrical contacts when pressurized (DIN ISO 1219-1). They are usually used for all applications where a electrical signal should be triggered whenever the set pressure is achieved or exceeded. This signal may be utilized to start a subsequent operation cycle (operation of a solenoid actuated directional valve) or to stop an operation cycle (cut-off of the pump drive, idle position of a solenoid actuated directional valve).
