Keller is the world's largest independent manufacturer of media-isolated, piezoresistive pressure sensors, producing in excess of 1 million units every year. Keller sensors are produced in three basic configurations: gauge pressure sensors, absolute pressure sensors and sealed gauge pressure sensors. Each of these types benefits from over 30 years of continuous development in our ISO9000:2001-accredited headquarters. Optimized mechanical packaging insures effective media isolation without degrading performance. A large percentage of OEM sensors produced by Keller are used in our own pressure transducers and pressure transmitters, so Keller understands the OEM viewpoint. Keller's designs cover a broad spectrum of applications, from medical vascular intervention systems to down hole oil tools. Whatever the requirement, Keller can provide the solution!
