3300/16-12-01-01-00-00-00 Framework Interface Module Bently Nevada
The 3300/16-12-01-01-00-00-00 XY/Gap Dual Vibration Monitor continuously measures and monitors two independent channels of radial vibration, and average shaft position (gap), accepting inputs from two proximity probe/ Proximitor® systems. This monitor is designed to supersede the 3300/16-12-01-01-00-00-00 Dual Radial Vibration Monitor, which does not provide radial position gap alarms.
Frequency Response: User-programmable for 4 to 4,000 Hz (240 to 240,000 cpm), or 1 to 600 Hz (60 to 36,000 cpm); – 3dB nominal. Note: The 1 to 600 Hz (60 to 36,000 cpm) option is not recommended for machine applications with rapid startup and coastdown rates where acceleration /deceleration exceeds 1000 rpm/s. Because of the extended low frequency range to 60 cpm, the monitor circuitry will retain vibration transients normally experienced during fast startups (such as with motor driven equipment). This can hold vibration levels above alarm setpoints beyond alarm time delays. This may result in Danger relay actuation after the internal time delay has lapsed, even if actual vibration has decreased below the Danger alarm setpoint level. If the standard 4 Hz (240 cpm) low frequency limit is not satisfactory for your application, contact your sales professional. The 1 Hz (60 cpm) option is recommended for applications where shaft rotative speed is less than 1,000 rpm.
