Our robust, highly accurate linear and rotary position measurement systems operate contact- and wear-free. They are extremely reliable, even in rough environments such as extreme temperatures, in salty air, in the presence of vibrations or shocks as well as in potentially explosive environments.
Gearless linear direct drives are increasingly replacing conventional systems in machine construction and automation applications. Absolute, high-precision multi-slide-capable magnetically encoded linear measuring systems for longer strokes are required for position feedback in the servo axes. Our new BML-G multi-slide-capable absolute measurement system is the ideal solution for linear direct drives. Its precise absolute signal is available over strokes of from 10 to 48000 mm. This increases its efficiency and reduces the multiplicity of parts and design costs.
The easy-to-maintain linear drive for short strokes, high cycle frequencies and accelerations can do without a cable drag train. The magnetically encoded tape of the BML displacement sensor is attached directly to the underside of the movable slide by means of a simple installation. The sensor head attached to the base plate always reads the slide position absolutely and without contact. The measurement signal is available as soon as the system is powered up, thereby ensuring high control quality and productivity.
Our BTL magnetostrictive linear position sensors in the hydraulic cylinder guide and position the slabs with precision. They check for the correct configuration of the lateral guides and accompany the slabs on their path through the rolling stand. In addition, the system safely compensates for the strong forces that occur during reshaping.
In the production of components made of carbon fiber reinforced plastic (CFRP), uniform pressure on the carbon fibers woven into mats is of central importance for an optimum result. Our heat-resistant BTL magnetostrictive linear position sensors ensure uniform shaping of the plastic and guarantee consistent pressure with every press-fitting process. They even work with high precision and great repeat accuracy in high temperature ranges – for every shape.
For fast and efficient drilling, pipehandlers take drill rods out of the magazine and position them directly over the borehole. Powerful hydraulics are needed in order to move the heavy rods. Our BTL magnetostrictive linear position sensors support the hydraulics and in doing so play a decisive role in promptly and correctly positioning the rods.
The flat design of our BTL PF profile magnetostrictive linear position sensors, which measure without contact, is perfect for tight installation conditions on the injection moulding machine. The contact-free, unguided position encoder enables rapid unit changeovers without the need for re-alignment.
Our BML magnetically encoded displacement transducers and angle measurement systems are the perfect solution for linear position detection: The measurement system measures fast and highly precisely, with a resolution of up to 1 μm and system accuracy of up to +/–7 μm. The system operates without contact and therefore entirely wear-free.
Control and shutoff valves are used in many areas of oil and gas extraction, in refineries and in petrochemical plants. Here, they not only need to be protected against harsh environmental conditions, but also against explosion hazards. Explosion protection has the highest priority in this environment. Balluff has the ideal solution for every application: Our certified BTL magnetostrictive linear position sensors have numerous international approvals and are extremely reliable.
