Sensata focuses on transmission pressure technology.Pressure-based transmission control systems have gained in popularity, as witnessed by GM's six-speed automatic transmission, which utilizes pressure-sensing systems to improve clutch feel and shifting performance. The sensors are produced by Sensata Technologies (www.sensata.com). "GM is leading with their new pressure-based control systems," says Abelardo Gonzalez, director of the Sensata Technologies U.S. automotive group and global transmission division. "These systems are much more accurate than speed-based technologies." Sensata offers a number of pressure sensor A pressure sensor measures the pressure, typically of gases or fluids. Pressure is an expression of the force required to stop a gas or fluid from expanding, and is usually stated in terms of force per unit area. A pressure sensor generates a signal related to the pressure imposed. technologies based on microelectromechanical (MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. ), ceramic capacitive and strain gauge strain gauge Device for measuring the changes in distances between points in solid bodies that occur when the body is deformed. Strain gauges are used either to obtain information from which stresses in bodies can be calculated or to act as indicating elements on devices for designs, Gonzalez is particularly keen on the continued development of MEMS for future transmission-based applications. "The line pressure stability in MEMS is excellent, not to mention it has a very low profile and is submersible submersible, small, mobile undersea research vessel capable of functioning in the ocean depths. Development of a great variety of submersibles during the later 1950s and 1960s came about as a result of improved technology and in response to a demonstrated need for ," he says. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. Sensata, the transmission pressure sensor market increasingly will require improved performance at the low end of the operating range (30-60 bar or less).--KMK |
