Transducers, Micropulse

Balluff GmbH has launched Micropulse® Transducers for partial-stroke testing on hydraulic valve drives. One ideal application area for this in a rod housing is providing position feedback for hydraulic cylinders in valve drives. They are therefore often located in linear-activated fixtures like stop valves or seat valves, but also in ball valves and shutoff gates with swivel activation in combination with special drive mechanisms (such as Scotch yoke, rack-and-pinion drive, etc). Partial-stroke testing of cylinders opens up another area of application in combination with the diagnostic options of smart position regulators. Using the absolute signal, the operating suitability of the valve can be monitored during ongoing operation, between the tests already scheduled during downtime. This results in fewer service interruptions and unscheduled stoppages for the system operator. Models with Ex approval are regularly used in explosive atmospheres, found in the Oil & Gas industry and in power plants. Micropulse transducers work without making any contact and are entirely wear-free and maintenance-free, providing the user with an extremely long service life.
