Beskrivelse

Number of channels 2 Space- saving dual- channel version reduces installation costs Easily accessible rotary switch makes adjustment simple Can be used up to SIL 2 (IEC 61508) 9147 series vibration transducer supply units connect vibration, acceleration and speed sensors to condition monitoring systems. The measuring signals are galvanically separated when they are transmitted. They are transmitted at frequencies of up to 50 kHz. These units have already been tested with numerous sensors from well- known manufacturers such as Bently Nevada and are in use in systems across the globe.
