The principles of Synchro are similar to those of an electrical transformer. However, 2 phases structure of resolver is used for angle detecting sensor, like Synchro. The actual achievement of angle accuracy is 2.78 second. The latter is used for angle detecting sensor of Nobeyama Radio Observatory in 1981. We both have highly-reliable and high-accuracy Synchro.

After the World War Ⅱ, we commercialized Japanese Defense Agency's standard (at that time), 60 Hz and 400 Hz types. When Tamagawa was founded in 1938, the main application was oil meter of aircraft. It is widely used in the harsh environment of shock, dust, high-humidity and high-temperature. The application is vessel, watergate and steel industry. We have been producing Synchro more than 70 years, since the institution's formation. Through the evolution of machine development, builders and system integrators alike, agree that the ‘ resolver’ transducer is unsurpassed in its ability to reliably supply rotary position data in the harshest industrial environments.Synchro Overview Highly reliable angle detector with long operating life Using simple onboard switches, technicians and engineers can easily select the unique resolution required by the application, thereby reducing the number of units that must be stocked. The Absolute Parallel and Incremental Digital versions can also be ordered with a field programmable option. Referred to as DuraCoders, these motion sensing devices are available with the following output types Absolute Parallel, Incremental Digital, Analog Current, Analog Voltage, and DeviceNet. Recent advances in technology have enabled the integration of a resolver and on-board electronics in one housing as an alternative to other types of encoders. In typical applications, the resolver sensor feeds rotary position data to a decoder stationed in a Programmable Logic Controller (PLC) that interprets this information and executes commands based on the machines' position. Product packaging plants and stamping press lines are perfect examples of where you might find resolver based systems at work. It was not long before numerous industrial segments recognized the benefits of this rotary position sensor, engineered to withstand the punishment of a military application. Referenced as an analog sensor that is absolute over a singl e turn, the resolver was originally developed for military applications and has benefited from more than 50 years of continuous use and development. Regardless of the names people choose to describe resolvers, their role in the world of automation remains unparalleled. On occasion, synchros (cousin to the resolver) are also mentioned when explaining devices of this nature.

When discussing RESOLVERS, people often interchange terms such as: encoders, rotary position sensors, motion feedback sensors, and transducer sensors.
