Pressure sensorsPressure switches for mobile hydraulic applicationsIn mobile hydraulic applications abruptly switching valves can lead to pressurespikes which are much higher than the operating pressure. In particularload monitoring requires the highest reliability. Quick and precise responseof the sensor is as indispensable for the protection of the process as clearand easy setting of the sensor. The highly resistant measuring cell can withstandextremely harsh operating conditions. The electronics allow quick andprecise conversion of the sensor signal into switch points.The new PP75 units of the mobile series are specially adapted to this use.A special feature of the pressure switches is the e1 type approval by theKraftfahrt Bundesamt (German Federal Office for Motor Traffic). The sensoris designed to have a high EMC and shock resistance.The pressure sensors often have to be mounted at places which are difficultto access in the vehicle or machine. Programming and reading of the valueson site are difficult. The solution: Sensors of the PP series with EPS interface.Pressure sensor and control monitor are located in the sensor housing onsite. Programming is performed using the programming unit (PP2000) whichis connected to the sensor by a cable. The sensors can be set by Teachbutton directly at the measuring point with medium pressure being applied.The current medium pressure applied is stored as measured switch point.As feedback for the successfully terminated operation the pressure switchgives an output signal which is confirmed by the LED lighting on the Teachbutton. This easy type of setting can also be activated or made by a remotebutton in a central operating panel or even automated by a plc. In addition,PP2000 can also be used as remote display. An electronic lock protectsagainst unauthorised access to the configuration.Easy set-upFor sensors with switching output the switch-on point and the switch-offpoint can be set to any value within the operating range independent ofeach other before the sensor is mounted. With this feature – called adjustablehysteresis – one single sensor can for example monitor two pressurevalues and give a signal if the current value is above or below the presetvalue at one of the two switching outputs. Damping and delay times can befreely selected by the user. After programming of the switch points the usercan lock the sensors electronically against unauthorised access.PP-series:Separate display /programmingunit.Technicalinformationand customerserviceGeneralinformationList of articlesMobilecontrollersI/O-modulesDialoguemodulesDiagnosisand serviceSensorsfor mobileapplicationsSignalconvertersConnectiontechnologyAccessoriesVisit our website: www.ifm.com107
