Transducer up to 2500 mm touchless absolute Series TIM Special features • rod style transducer • for integration in pneumatic and hydraulic cylinders • touchless magnetostrictive measuring process • non-contact guiding with ring-shaped position marker • unlimited mechanical life • no velocity limit for position marker • absolute output voltage or current • outstanding accuracy performance up to 0,04 % • repeatability 0,01 % regardless of stroke length • operating pressure up to 350 bar, peaks up to 530 bar • wide range of supply voltage • EMC for mobile applications • immunity against HF fields up to 200 V/m • screw flange M18x1,5 or plug-in flange Ø 48 mm • other flanges on request • optionally plug, cable or lead wire connection This absolute position transducer can be integrated directly in the pressurized zone of pneumatic and hydraulic cylinders, thereby providing compact and cost-effective position sensing. The transducer consists of a stainless steel flange welded on a stainless steel pressureproof rod and the moving position marker. Signal processing electronic is completely build-in the flange. The transducer rod fits into the bored piston rod. The position marker is mounted on the piston bottom. The complete transducer is mounted inside the cylinder and protected against external influences. This feature with highest durability is favoured especially for mobile applications in harsh environments. Mounting is also possible in clevis-head cylinders or any space limited cylinder applications. Description Housing Rod and flange stainless steel Mounting Bushing M18x1.5 for screw plug hole per ISO6149 Plug-in flange Ø 48f7 for mounting bore Ø 48H8 Position marker Ring position marker, plastic Measuring technique Touchless, magnetostrictive Electrical connection 4-pin round connector, unshielded, M12x1 (only screw 3 conductor cable, unshielded, 1 m long (0.5 mm2) 3 lead wires, 100 mm long (0.5 mm2) Lead wires with 4-pin plug system M12x1, IP69k Electronics Integrated SMD with ASIC The touchless magnetostrictive measuring process offers superior accuracy and high dynamics. The measuring process is independent from environmental media like hydraulic liquids. The high mechanical ruggedness of the transducer combined with the underlying measuring technique means that the system is highly resistant to shock and vibration. The measurement is accomplished using a passive ringshaped position marker which can be moved as a free-floating element. The touchless coupling makes installation even simpler. The wear-free operation means unlimited mechanical life expectancy and unlimited traverse speed of the position marker and permits stroke lengths up to 2500 mm. The transducer’s integrated signal processing transforms the position information directly into market standard voltage or current outputs. Since the outputs are direct, no signal-conditioning electronics are needed when interfacing with controllers meters. The transducer complies the usual EMC requirements of agricultural and forest machines and vehicles. In addition to the standard configuration, the modular design provides customer specific terminal flanges and mounting variations.
