Sensonics DN2601AV Machine Protection Unit - Single-channel installed machine and bearing vibration monitoring and protection unit

The supervised machine is completely safe with the Sensonics DN2601AV machine protection unit. The device is virtually maintenance-free and performs continuous self-checks on its measuring channels and attached measuring circuits for safety. The unit is capable of receiving one ICP-powered (with built-in charge amplifier) piezoelectric vibration acceleration sensor. The monitoring unit of type DN2601AV can be applied to all types of rotating machinery: such as electric motors, pumps, fans, compressors, mills, grinders, mixers.

• one vibration acceleration sensor can be connected
• signal processing: - vibration velocity in low frequency range (machine condition) - vibration acceleration in high frequency range (bearing condition)
• two freely adjustable alarm threshold values
• built-in digital display
• many selectable measuring ranges
• adjustable lower and upper frequency limits
• continuous channel and sensor checks
• compact, DIN rail mountable housing

• buffered sensor signal (BNC, for measurement and analysis instruments)
• 2 x 4 ... 20 mA current output (proportional to vibration level)
• 2 x 2 alarm level relay outputs (with selectable operation)
• 1 fault indication relay output (operated based on self-check)

The DN2601AV device processes the sensor signal according to the set measurement range and signal integration, then outputs current signals proportional to vibration velocity and vibration acceleration. The buffered sensor signal is available on the BNC connector for further evaluations.

The operation of the two alarm relay outputs per processed vibration signal is based on the appropriate signal levels. If any vibration characteristic exceeds the set predictive or protective threshold value, the corresponding predictive or protective LED lights up, and the corresponding relay contact also switches.
