ELECTRONICS: Trans-Tek has created a unique category of Linear Displacement Transducer (LVDT), originally developed for a manufacturer of tools for the down-hole oil drilling industry. The products are the result of a collaborative, creative process that produced several iterations for increasingly deeper pressures and higher temperatures. Two models evolved, based on the company’s Series 230. However, Trans-Tek can add the same features to any stroke AC-AC LVDT. Other applications outside of the oil industry include R&D testing and nearly anywhere extreme environments exist.To accommodate such high pressure, the transducer housing is perforated to equalize pressure inside and outside the LVDT. Since the holes in the housing expose the coils inside, the fluid must be electrically non-conductive and chemically benign. Of course, many hydraulic oils meet this requirement. The high temperature ratings are achieved by using special internal materials.
These LVDT’s are rated for pressures to 35,000 psi, in electrically non-conductive, chemically benign media, at continuous temperatures as high as 450F. Non-linearity is ±0.25 percent and temperature coefficient of sensitivity is ±0.01 percent per degree/F. A high sensitivity output offers infinite resolution in a variety of strokes. Trans-Tek high-temp/high-pressure LVDT’s are available in a choice of 3/8- or ¾-inch OD body style with signal conditioners for dc-dc or 4-20 mA operation.
Trans-Tek was formed in 1967 to manufacture a broad line of Linear and Angular Displacement, and Linear Velocity Transducers. The company has grown from a small startup to a multimillion dollar manufacturer operating from a 14,000 sq. ft. facility. All transducers are produced in Ellington, CT.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
