Product Introduction
The Bently Nevada 1900/65A-00-01-01-01 is a general purpose equipment monitor designed for continuous online protection of industrial machinery. It is part of the 1900 series, intended for balance-of-plant (BoP) assets that do not require full 3500 system functionality. This model provides vibration and temperature monitoring with relay outputs for alarm and shutdown.
The part number configuration indicates:
1900/65A – Base monitor, 4-channel (2x vibration + 2x temperature or 4x vibration)
00 – No internal modem
01 – 24 VDC power supply
01 – Standard input/output (4–20 mA retransmission)
01 – No communication module (no RS-485/Modbus)
01 – Standard enclosure (IP20, panel mount)
It supports accelerometers, proximity probes, and RTD temperature sensors. The monitor calculates overall vibration amplitude and provides programmable alert and danger setpoints with time delay.

Application Scenarios
This monitor is typically used in balance-of-plant machinery where continuous online monitoring is needed but a full-scale protection system is not justified. Specific applications include:
Fans and blowers – Monitoring bearing vibration and temperature to prevent unplanned downtime.
Pumps – Centrifugal, positive displacement, and cooling water pumps in power plants and water treatment facilities.
Small compressors – Reciprocating and screw compressors for air or process gas.
Motors and gearboxes – General industrial electric motors (up to medium size) and speed reduction units.
Conveyor drives – Monitoring critical rotating components in material handling systems.
HVAC chillers and cooling towers – Equipment in commercial or industrial HVAC applications.
