With pressure at zero the micro-switch remains pressed and will only be released when the adjusted switching pressure has been reached. In case of higher pressure the ram works against the sp The piston pressure will then depend on the initial spring force. Adjustment by turning the screw top (or knurled knob) which can be fixed with a screw. The complete adjusting travel is approx. 9 mm. Admissible ranges of application for pressure components, series DS hazardous fluids* Pmax. 00 non-hazardous fluids* Pmax. 000 * According to the regulation on hazardous materials In the meaning of paragraph 9, sub-paragraph of the regulation on pressure components DGL 97//EC For applications with higher pressure please contact our technical department! In order to retain service-life over a long period vibrations, oscillations and high switching currents resp. inductive loads should - as far as possible - be avoided.

8 Hysteresis for DS-07/DS-0. Standard sealing: Pressure switch Type DS-07/0: For an adjustable pressure of approximately 60-70% of the max. adjustable pressure the Hysteresis is approximately 7-% of end value. These values are dependent on the temperature and viscosity of working fluid. Example: DS-07/00 Adjusted pressure: 70 pressure range: 0-00 Hysteresis: approx. 7-. Special sealing (low friction) type "SS" Pressure switch Type DS-07/SS: For an adjustable pressure of approximately 60-70% of the max. adjustable pressure the Hysteresis is approximately -6% of end value. These values are dependent on the temperature and viscosity of working fluid. Example: DS-07/SS-00 Adjusted pressure: 70 pressure range: 0-00 Hysteresis: approx. DS-07/SS- Adjusted pressure: 00 pressure range: - Hysteresis: approx.

The speration is done by a stationary mounted membrane. This model based on a housing with flange connection is particularly appropriate for heavily polluted and dense fluids such as sewage, sludge etc. In the coal mining industry cementitious grout is sprayed under pressure on the mine walls to bind the coal dust. These units have been developed for this application with the co-operation between and the uhrkohle AG mining research station Essen. For bigger quantities, special designs are possible on request.
