Ohio Semitronic成立于1964年，布尔曼博士在美国制造出OSI第一家向市场推出和发展霍尔效应器件。OSI最初的产品是基于霍尔效应测量原理布尔曼博士在1952年概括这段时间以来传感器，OSI发展迅速，发展了一些精确的电气和电磁测量技术，以及超过13,000的产品，OSI的13,000产品线已发展到包括电压传感器，公司产品受到客户的需求不断扩大推动。随着客户不断创新，开发OSI，创建了一个测量解决方案，OSI提供一系列的精度和线性度指标的同时匹配其客户的技术和经济需求。每个精度和线性度规格可根据NIST认证和ISO 17025精度要求的一致性，因此仍然OSI ISO 9001：2008 2009年以来的认证。产品范围：Ohio Semitronic传感器、电流传感器、变送器、电流互感器、电流继电器、开关、电流转换器、电流变送器、电压传感器、隔离转换器、电流开关等.
Ohio Semitronics, Inc was founded in 1964 by Dr. W. E. Bulman, a pioneer in the then-emerging field of solid state physics. Dr. Bulman made OSI the first company in the US to market and develop Hall Effect devices. Because of Dr. Bulman, and OSI’s President Emeritus John Redmyer, OSI has technological roots in both Battelle Institute and Bell Semitronics, Inc. develops and delivers power measurement technologies such as, transducers and current sensors from its plant in Hilliard, Ohio. OSI’s range of measurement technologies perform in a variety of demanding environments such as, Petroleum and Petrochemical, Electric Utility, Solar and Wind, Test and Measurement, Automation and Control, and Naval surface and subsurface applications.
