BENTLY NEVADA 135321-01 3300/16 Dual Vibration Monitor
Description
The BENTLY NEVADA 135321-01 3300/16 Dual Vibration Monitor is a dual-channel monitoring device designed to replace the 3300/15 dual radial vibration monitor, which lacks radial position gap alarm functionality. It features two independent channels that continuously detect and monitor radial vibration and average shaft position (gap) via inputs from two proximity probes or systems. Key programmable features include a user-selectable power supply of -24 Vdc or -18 Vdc, with current limiting integrated on the individual monitor circuit board. Users can also program the frequency response to either 4 to 4,000 Hz (240 to 240,000 cpm) or 1 to 600 Hz (60 to 36,000 cpm). Note that the 1 to 600 Hz range is not recommended for machine applications requiring fast startup, specific inertia decay rates, or acceleration/deceleration rates exceeding 1000 rpm/s, as the extended low-frequency range down to 60 cpm retains vibration transients common during fast startup, which may cause alarm delays with vibration levels remaining above setpoints post-alarm trigger.
