Muscle-Powered Hydraulics Features Position Feedback

The hydraulic-cylinder position feedback signals are generated by Hall-effect linear transducers from Rota Engineering. The firm’s linear transducers are usually installed inside a cylinder by boring into the center of the cylinder’s piston rod. This setup provides a compact assembly and protects the sensor inside the cylinder’s relatively secure environment. However, with the MACIF, the transducers’ sensing elements mount onto the OD of the cylinder tube…

Terex Introduces Electric Boom Lifts Using Rota Hall Effect Sensor

Rota Engineering LTD, the premier mobile hydraulic cylinder linear sensor supplier, provided a sensor for the Z60 machine’s closed loop control of the steering system with focus on meeting Terex AWP’s requirements to keep the machine’s goal of being “green” in the environment…

Cylinder Sensing Without Rod Drilling

Rota Engineering in the United Kingdom has a range of linear transducers that are used in agricultural and construction machinery because of their compact design that do not usually extend a cylinder’s mounting dimensions, which are mounted inside a cylinder’s drilled-out piston rod that carries a small ring magnet to achieve a non-contact operation. They are a robust choice of using a transducer…

Big Rigs Walk the Walk

Rota’s LDTs give accurate and repeatable position feedback and can be fully imbedded in the rams, with just the electrical connection visible. All electronics are imbedded in the transducer within the ram. Stroke of the lifting rams is closely and continuously monitored to ensure safety by keeping the rig level. The rams stroke up to 9 ft moving at 4 ft/min, with typical pressures to 2,500 psi…

Sandvik Mining finds a unique use for a linear position sensor

The solution came from Rota Engineering, a manufacturer of position sensors with internal and external solutions. In this application, the cylinders had a very long stroke and the cost to gun drill the cylinder rod for an internal solution was cost prohibitive. An external design, where the sensor was mounted stationary (coloured red in the image below) in the drill mast while a magnet travelled with the drill head, solved the problem…

A technology’s reach expands, both figuratively and literally

Rota has introduced a new external modular transducer geared toward tough cylinder applications such as double-ended cylinders that can’t have internal technology put inside, or for extremely long stroke cylinders that would either cost too much to gun drill, or are problematic to build, ship, store and install…

To simplify or not to simplify, that is the question

While oftentimes simplification is the goal for system and equipment manufacturers, there are certain applications where a more costly upfront investment for customized sensor technology makes sense. Rota Engineering, Manchester, UK, specializes in the design and manufacture of position transducers and ex connector systems, as well as offers engineering solutions for customized multi-parameter sensors with combinations of position, pressure, velocity and temperature measuring capabilities…

LDT lets AGCO RoGator adapt to the task at hand

Rota Engineering’s sensors use a microprocessor that transmits and receives signals from Hall-effect chips mounted to a printed circuit board. The circuit board is contained within a stainless steel or aluminum housing, depending on application requirements. A piston-mounted magnet causes a voltage drop when it passes over the Hall-effect chip. The microprocessor calculates the position of the Hall-effect chip and correlates the voltage drop to a proportional voltage, current, PWM, SSI or CAN output….

Smart rephasing cylinder complies with small ASAE tie rod package.

Tie rod cylinders have long been the workhorse of ag equipment. But, in general, designers had to choose between either resistive or magnetostrictive linear displacement transducers (LDTs) to provide cylinders with electronic position feedback capability. An alternative to these conventional solutions is offered by Rota Engineering Ltd, Manchester, U.K. Mark Hoffman, of Rota Engineering’s US facility, Allen, Texas, said the Rota Engineering sensor uses Hall effect technology to monitor the position of a magnet embedded within the cylinder’s piston…

Smart cylinders maintain the gap

Rota Engineering’s design of LDT eliminates the need for a gun-drilled piston rod. It uses Hall-effect technology to sense the position of a magnetic piston through the barrel of a cylinder. A linear Hall-effect sensor positioned along the length of the cylinder barrel detects the position of the cylinder’s piston by sensing the position of a magnetic field formed by a permanent magnet embedded in the piston. As the piston rod extends or retracts, the magnetic field propagates through the cylinder wall to communicate with the linear Hall-effect sensor…
