Beacon industrial electronics provides ac tachogenerators generally used by turbine manufacturers. These ac tachogenerators have a standard output of 1 v ac per 100 rpm and have an operating range of 0 to 6000 rpm of the actual rotation without any ratio involved. The output voltage can be decreased or increased depending on the customer`s requirement. These tachogenerators find its application in various fields like paper, plastic, textile, sugar, fertilizers, oil and gas, shipping as well as by the indian navy. The tachogenerators are available in different mounting arrangements, such as flange mounting, direct mounting, base mounting, pedestal mounting as well as other custom designs. These ac tachogenerators can be used to drive analog or digital tachometers, which would be used to display the speed. The ac tachogenerators are rugged in design and are able to operate efficiently even in temperatures up to 60dc and humidity of 95 per cent rh.
