TWK has developed a new generation of inclinometers. They measure more precisely and faster than before, and are insensitive to interfering acceleration and lateral inclination excursion. These sensors are highly suitable for applications with dynamic requirements in which precise inclination angles nevertheless have to be registered and transferred to a control system.
TWK is the first sensor manufacturer to offer an inclinometer for SIL2/PLd applications with PROFIsafe via a PROFINET interface.
Modern control technology and automation have taken over important functions in this area of materials handling technology, marine crane technology. TWK has been developing and manufacturing the sensor systems required registering positions for this for over 50 years.
Like many plant manufacturers, operators of mountain cable railways are also compelled to meet the requirements of the European Machinery Directive in the event of conversions or new purchases. Certified electrical components with a known performance level help to implement safety functions.
Sport is healthy. Movement keeps the circulation going and strengthens the muscles. This "truism" applies to all age groups. The joints and locomotor system should be promoted - without overtaxing them. Injuries during sports should be avoided wherever possible. The rules of the respective sport as well as the sports equipment and the surroundings, e.g. the sports hall, contribute to this. The essential part of a sports hall is the hall floor. It differs from the usual floors in houses and offices and on the road.
There are a number of different options for precisely measuring linear distances or movements. Depending on the requirements concerning the measuring range and accuracy, measuring tapes, calipers or micrometer screws are used, for instance. All of these measurements are based on comparison with a measuring tool which is used as a reference. The most well-known reference for length measurements is the original metre standard in Paris.
The company named SkySails was founded in 2001 in Hamburg, and entered the maritime market with a ground-breaking idea. The intention was to support vessels' drives with gigantic towing kites, thus reducing fuel consumption by an average of 10 – 30% per annum.
"Safety last!" - this is the motto used by Harold Lloyd in the 1920s to climb the façade of a high-rise building in his eponymous film. He also made it to the top - and how! Things shouldn't be this daring, barely scraping by catastrophe by a hair's breadth. So safety first is preferable, after all: this is how machines, systems and operating equipment should be designed so that nobody falls from a great height or is harmed in any other way. Harold Lloyd would have been delighted back then.
Occasionally, you have to just switch off. But when is the right point in time? In the case of a wind turbine that has to be powered down in the event of danger, the mast vibration phase - zero-axis crossing or maximum - in which the turbine is stopped to prevent the mast from receiving an 'additional kick' that causes damage may be crucial. This point can be set precisely with the new SIL2 vibration sensor NVA115 from TWK.
The higher the more wobbly - this should never be the case, of course. Quite the opposite: the standard of safety should not suffer from aiming high. Cranes and mobile cranes as well as lifting platforms must therefore be equipped with safety sensor systems to always guarantee stability and operating safety.
Vibration monitoring is becoming increasingly important in machines and systems. The increasing demands are necessitating corresponding safety components. TWK offers a range of certified SIL devices. They register rotational angles, inclination angles and also oscillations and vibrations - 'safely'.
A context that comes into play twice. On one hand, the availability of a wind turbine should be high. This means very few turbine or sensor system failures and low maintenance effort with few repairs. On the other hand, turbines are increasingly being equipped with safety sensor systems. The Germanischer Lloyd guidelines additionally underscore this development. Certified safety components are therefore increasingly being used in wind turbines – e.g. with SIL2 certificate.
