Electronic Air Core Wide Angle Tachometer 750437

The wide angle air core tachometer has been developed as an alternative to the D'Arsonval type tachometer. Differences between the air core mechanism and D'Arsonval meter movement have forced the design of new drive electronic circuitry which would transform a linear output voltage to two bi-directional output wave forms. Combination of the new circuit and existing gage assembly is built into a tachometer assembly and is being produced in high volume utilizing automated assembly and computerized laser test and adjust equipment. Expansion of the concept will allow application to pressure and temperature gages, pyrometers, speedometers, etc.
