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.
Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Plastic may not be the most beloved of materials to the more environmentally minded, but Plasti 2012 aimed to mold a different opinion of the material in people's minds.
The rare earth element market has become steadily more rational, and new sources coming online will continue to reduce costs. Still, it is unlikely that prices will drop to their former lows.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
