The 1900/55 Fan Monitor is a four-channel monitor intended for low frequencyvibration monitoring on fan gear boxes. Although the monitor accepts input fromany Velomitor" transducer, the 190501 Velomitor'CT transducer must be usedfor low frequency applications. This transducer will give you a response from 1.5to 1000 Hz± 3 dB which will give the needed response for monitoring fan speedsof 90 RPM or greater.

All programmable options of the monitor can be set through the front panelcontrols without using switches orjumpers. The programmable options includerelay time delays, latching or nonlatching relays, de-energized or energizedrelays, danger relay bypass, LCD scan time, measurement units, and point lD

The monitor can be ordered with a communication card or one can be added tothe monitor in the future. A communication card allows the monitor to sendcurrent vibration levels to a plant computer or to some other system. Thisvibration information can be trended so that changes in vibration over time canbe analyzed.
