Predictive maintenance ! Measurement of bearing condition ! Machine protection systems ! Machine control systems ! Machine monitoring systems Characteristics: ! Measurement of vibration (mm/s, in/s) in freq.band 10-1000Hz ! Measurement of bearing condition (HF parameter, g=9.82m/s2) in freq.band 5-16kHz ! Wideband measurement of acceleration (g=9.81m/s2) in freq.band 0.8Hz-16kHz ! Measurement of TRUE RMS and TRUE PEAK values ! A3900-II settings from computer via RS232 interface ! A3900-II is possible to connect to memory module for data storage (standard CompactFlash card) ! Adjustable current loop 4-20mA for actual value output ! Complete checking of failures. Current of the loop drops to 3.5 mA immediately and the control system does not generate any incorrect response ! Indication of exceeding the predefined vibration limits (ALARM, ALERT) ! ALARM limit relay ! The quality acceleration ICP sensor is used ! Continuous check of break of cable or sensor ! Simple connection to control systems (PLC) ! Simple installation to DIN rail Ref: 07032006RS " User’s guide
