Micropulse ARTransducers
Position detection inmobile hydraulics
Sensors are being usedincreasingly to extend usefullife and improve safety inmobile equipment. The newMicropulse AR Transducerfrom Balluff senses thepiston position in mobilehydraulic cylinders.The sensor operates on theproven magnetostrictiveprinciple. The compact sizeof the transducer makes itideal for use in pivot bearingand spherical eye endcylinders or large borecylinders. The processingelectronics integrated in thetransducer has beendesigned to meet the strictEMC Directives for industriallift trucks, agricultural andforestry equipment andearthmoving machinery.

The propagation time of anultrasonic wave, induced bymagnetostriction, is used todetermine the position of themagnet.
The position is output as ananalog value which rises.This is done with highprecision and repeatabilitywithin the measuring areadesignated as the nominalstroke length. If there is nomagnet within the measuringarea, an error signal isoutput. At the rod end is adamping zone. When amagnet is in this zone theoutput is spurious. Theelectrical connectionbetween the transducer, thecontroller and the powersupply is accomplishedusing a cable or pigtail.

Block diagram of the P-interface
P510 interface
Compatible with Balluff BTAprocessors and controllersand modules from variousmanufacturers, includingSiemens, B & R, Bosch,Phoenix Contact, Mitsubishi,Sigmatek, Parker, Esitron,WAGO and others. Reliablesignal transmission even overcable lengths of up to 500mbetween the BTA processorand the transducer isassured by the especiallynoise-immune RS485 diffe-rential drivers andreceivers. Noise signals areeffectively suppressed.
P510 universal forrising and falling edgeevaluation
As a consequence of diffe-rent control philosophies,digital pulse interfaces areavailable in two differenttypes depending on thecontroller.The difference is in whichedge is used for processing.In the "P-interface" the fallingedges are used for timing
and in the "M-interface" therising edges.To reduce the number ofdifferent models to aminimum, the "P510-interface" was created as auniversal pulse interfacewhich combines bothfunctions.The reference point for thepropagation timemeasurement is the "Start"pulse.

Objective: Simulate themechanical loads on aproduct over its working life.Balluff products are oftenfitted in machines whenmechanical vibrations andimpacts occur. For reliableoperation they must bedesigned to be immune tovibration and shock. In theBalluff test laboratory allproducts are therefore testedbefore series release fortheir mechanical stability.
The features of the vibration test equipment at Balluff are as follows:
Manufactured by Unholtz-Dickie CorporationModel SA 15-S092-BP SAI60-H560B-24-LPsinusoidal force vector 4.4 kN 35.6 kNrandom force vector 4.4 kN 35.6 kNshock force vector 8.8 kN 73 kNmax. sinusoidal acceleration 100 g 89 gmax. random acceleration 100 g 74 gmax. shock acceleration 200 g 210 gmax. sinusoidal velocity 2.0 m/s 1.9 m/smax. shock velocity 5.1 m/s 3.5 m/smax. amplitude 51 mmp-p 51 mmp-pFrequency range up to 3.5 kHz up to 2.7 kHz
The following tests can beperformed on thisequipment:
– Sinusoidal testing– Noise testing– Shocks
in addition one equipment iffitted with an FFT analyzer.
Tests can be performed tothe following standards:
MIL STD 202EN 60068-2-6EN 60068-2-27EN 60068-2-29EN 60068-2-64DIN EN 50155IEC / EN 61373GL 2001
Reliability doesn't happen by chanceTests and checks during the development process improve theproduct and give protection against "surprises" in service.

Closed-loop controland higher dynamicswith SSI-SYNC
The absolute positioninformation from theMicropulse Transducer issent synchronously tothe axis control card. Thissynchronous dataacquisition enables exactcalculation of the velocityand acceleration.
The right feedbacksystem forevery application
– Non-contact, wear-freesystem
– Very reliable with highprotection rating
– Pressure rated forintegration in cylinders
– Wide variety ofinterface options
– Special form factors,e. g., for EX or redundantapplications
By feeding these statevariables (velocity andacceleration) back, thedamping and naturalfrequency of a hydraulicsystem are increased. Thesemeasures permit greaterloop gain and with it bettercontrol behavior and higherdynamics.
