                                    Easy to install
                                    Ideal overall dimensions, can be mounted in any operation position, turnable under full pressure around the longitudinal axis, instrument plug turnable by 4 x 90°.

                                    Universal application
                                    7 pressure ranges for the optimal adaptation to any operating pressure, suitable for mineral oils (HLP-oils according DIN 51524), other mediums on request.

                                    Damping
                                    For the protection of the pressure switch we recommend the installation of a damping element as for example a throttle screw with double fitting according to the table below.
