Magnetostrictive position measurement systems come into use generally where high reliability and precision are demanded in position and speed measurement.
Over long distances, our contact-free and absolute measuring systems are suitable for all industry-standard interfaces and for a wide range of applications. Even under extreme surrounding conditions, they guarantee a high machine and system availability.
The magnetostrictive linear position sensors in a profile design from Balluff are contact-free and absolute measurement systems for precise detection of one or more positions. They deliver convincing performance in harsh environments, for example in presses, injection molding machines or gantry robots, because they are made of an hermetically sealed IP67 aluminum housing. The magnets of the position encoder act on the measurement element through the wall of the aluminum profile.
The measurement systems have flexible installation options. You can get the required position encoder in a floating or captive version. Floating position encoders are secured directly to the machine component to be measured and move along with it at a certain distance above and along the profile. The advantage here is that the guiding precision is not subject to stringent requirements. The measurement systems tolerate a horizontal and vertical offset of just a few millimeters.
The most important application for our magnetostrictive linear position sensors in rod design is in hydraulic drive units. They are exceptionally well-suited for use in hydraulic cylinders for position feedback, for molding lines and rolling mils or for elevator and hoisting technology.
Because the sensors are installed in the pressure area of hydraulic cylinders, they have to have the same pressure resistance as the cylinder itself. The measurement element is installed in a pressure-tight tube made of non-magnetic stainless steel. The flange seals the high pressure area using an O-ring. The electronics are integrated in a protective housing outside of the cylinder on the flange of the rod.
Whenever you need to measure with absolute precision, you can count on the linear position sensors from Balluff. Our systems are made completely of stainless steel and are designed up to IP69K or for high pressure cylinder applications up to 1000 bar. Their contact-free working principle prevents wear and ensures almost unlimited service life. Therefore, Balluff offers you a high degree of reliability and precision, even under the most extreme conditions.
Our multiple redundant position measurement systems meet the highest requirements for security and availability, even in harsh environments. For example, when used in safety-relevant valves and hydraulic cylinders. They offer up to three independent measurement systems in the same housing and thereby ensure increased safety during operation. The different interfaces enable diverse redundancy.
Many applications require the use of transducers in explosive atmospheres. Pressure-encapsulated magnetostrictive linear position sensors are available in different rod designs and with varying performance profiles for use in Ex-zones 0 and 1. There are variants for use in areas where there is a risk relating to gas or dust as well as magnetostrictive linear position sensors for Ex-zone 2 that can withstand the potentially explosive conditions there.
The housing of the BTL-J-DEXC-TA12 is robust and pressure-encapsulated, and its electronics module can be changed quickly and easily. This means that these variants meet the requirements set by the oil and gas industries for high reliability and easy service for the Ex-zone.
The BTL-SF fill level probe enables continuously precise measurements in applications that demand an exceptionally high level of hygiene. Made from non-corrosive stainless steel, with high surface quality and rounded edges, this measuring system meets the highest international hygiene standards and thus fulfils all prerequisites of the strict regulations relevant to the food industry.
