FlexiDrive S
Balluff’s explosion p roof Linear Transducer
he New 2013 Linear Position Sensing and Measurement from Balluff features the Micropulse TA12 explosion-proof linear position transducer now has IECEx explosive atmospheres approval rating, in addition to existing ATEX approvals, expanding the acceptability for the Balluff
T
TA12 transducer for worldwide use in applications where hazardous gases and/or dusts are
present.The Micropulse TA12 is a non-contact linear position sensor with a compact, explosion proof housing.
It is specifically designed for
continuous feedback on hydraulically and pneumatically actuated valves for oil and gas refining,
storage, transport, and handling.
The magnetostrictive sensor is designed for both extended duty and quick replacement – key attributes in the busy energy sector. Non-contact, wear-free magnetostrictive technology ensures long life and MTBF for maximum production uptime. In the rare instance where the unit does require service, the TA12 incorporates its electronics and sensing hardware in a Rapid Replacement Module (RRM) that allows fast field repairs by the customer.

mith Flow Control’s FlexiDrive valve actuator can be applied to any conventional wheel-operated device in
The FlexiDrive is a
dependable, versatile and cost effective remote valve operator. The FlexiDrive system allows a user to locate a point of operation in a place of safety or convenience.
It is
adaptable to any conventional valve with no modifications needed.
A patented flexible linear drive cable effectively
delivers rotary torque for distances up to 30 metres depending on the output torque required. The system can be passed through and around walls, bulkheads and floors, and is completely sealed and permanently lubricated for maintenance-free, continuous loop operation. The FlexiDrive is suitable for underwater use and is constructed from corrosion-resistant 316 stainless steel. It is designed to withstand temperatures from -22 to 347 degrees Fahrenheit and is delivered as a complete unit.

Custom-tailored drive units for baggage handling
international manufacturer has already equipped numerous airports throughout the world in locations as varied as Hamburg, London, Johannesburg, or Taipei. The drive expert’s dedicated
N
internet portal –
http://airport.nord.com/ – provides a concise presentation of solutions for the industry. NORD’s economic drive systems are based on efficient 2-stage helical-bevel geared motors that are especially easy to handle due to the lightweight gearbox design. In addition, NORD offers an electronics program featuring uniform operation across a differentiated, but manageable model range. Airport drive solutions include horizontal conveyors e.g. for check-in areas that perform simple start- stop operation as well as drives with high overload capability and brake management to propel incline conveyor belts and vertical conveyors. Economic motor-integrated frequency inverters ensure high dynamics and precision in lifting and sorting tasks. Basic screw and plug connections are all that is necessary for avery comfortable installation of these drives. .

The
torque transducers T40 family of H New precision gears
n the basis of the very successful RV-E series Nabtesco has developed the RV-N series with even more compact, more lightweight and more powerful precision gears. Numerous applications such as robotics, as well as rotary tables, machine tools and others require high torques, but offer only limited installation space. In addition, very fast and precise positioning movements have to be carried out with high payloads, and without backlash. This is exactly where the RV-N series shows its strengths: it is especially lightweight and compact, yet has a heavy-duty construction, which makes it ideal for entirely new applications. The compact design is achieved by means of a main bearing with an integrated inner race. High power density is possible due to reinforcement of the eccentric shaft bearing. The dimensions of the new gear are much more compact than the previous series – the power data remains at a comparable level with an average reduction by one size. Reduction of the weight by 40% reduces the mass inertia and therefore improves the load conditions. Special heat treatment of all components during the production process ensures high thermal stability of the gears and a significantly longer service life. The series is available in diverse sizes with rated torques from 245 to 7,000 Nm.

BM’s T40 family of torque transducers has been developed to set industrial standards with its
integrated, magnetic rotational speed measuring system utilizing reference signals that allows rotational speed and positional controls to be implemented in test benches.
The rugged
construction of the T40 family is designed to give high accuracy and excellent reliability. The integrated, magnetic measurement system for the HBM T40 family has been specifically designed to overcome the effects of humidity, condensation, dust, oil and grease that restrict the effectiveness of optical measurement systems.
The T40B family of
torque transducers provides measuring ranges of up to 50 Nm for various applications while the T40FM range covers maximum range options of up to 80 kNm. All models in the T40 range benefit from an output pulse count over all ranges of 1024 pulses per revolution. This makes it possible to implement resolutions of up to 12 bits in any downstream electronics depending on the evaluation method such as pulse quadrupling.
