µFORS-3UC

Northrop Grumman LITEF‘s Fiber Optic Rate Sensor μFORS is designed to meet the requi-rements of a wide range of air, land and sea applications.

Using the latest technology, it provides com-pensated angle or angular rate outputs via its digital interface, which can be set to either asynchronous or synchronous operation mode.

With small volume, low weight and small power consumption, the μFORS can be integrated easily. Its configurable measurement range makes it an ideal candidate to standardize system design, thereby reducing system comple-xity and cost.

Free from effects of gravity induced errors, and with no moving parts, Northrop Grumman LITEF‘s μFORS is insensitive to shock and vibration. It offers high reliability without the need for periodic maintenance.
