1900/65A General Purpose
Equipment Monitor

Traditional Bently Nevada* monitoring systems like the 3500
Series are widely recognized for protecting large, complex
rotating machinery. However, it is generally diffi cult to justify
this type of continuous monitoring for less critical, essential
or general purpose equipment. As a result, these machines
typically operate without adequate protection.

The Bently Nevada 1900/65 General Purpose Equipment
Monitor is a fl exible, cost-effective system specifi cally designed
to continuously monitor and protect essential and balance-of­plant equipment assets in a wide range of industries including:
Oil & Gas, Power Generation, Water Treatment, Pulp & Paper,
Manufacturing, Mining, Cement, and others. The 1900/65
Monitor is suitable for monitoring and protecting cooling tower
fans, pumps, blowers, motors, pulverizers, air compressors,
small reciprocating compressors, small electric motors, small
hydro turbines, centrifuges, and other equipment assets.

Benefi ts

• Lower-cost, continuous online protection than traditional
rack-based systems

• Digital connectivity via optional Modbus® gateway serves
rich static variable set, alarm statuses, and event list data
to Distributed Control Systems (DCSs), Programmable Logic
Controllers (PLCs), Supervisory Control and Data Acquisition
(SCADA) Systems, and System 1* Optimization and
Diagnostic Software

• Reliable system offers improved capability over transmitters
for equipment protection

• Uses proven and reliable circuit designs as found in 3500
and 3300 monitoring systems

• 8-channel monitor offers greater number and variety of
inputs than other 1900 Series monitors

• Easy installation and confi guration through small size,
fl exible mounting options, and confi guration software

• Monitor functions independently or with an optional display
for local indication of all channels and variables

• Display can be mounted directly to the monitor or up to 250
feet away and connected to the monitor via a single cable

• Particularly suited for use on standalone, skid-mounted, and
packaged machinery

• Packaged and designed for cost-effective OEM applications

• Simplifi ed, less costly on-line installation via 232 or 485
connectors.

• Flexible Dynamic channels can be confi gured for vibration,
position or speed

Capabilities/Specifi cations

• Self-contained, stand-alone monitor

• Continuous monitoring and protection, suitable for auto­shutdown applications

• Optional Modbus gateway communicates via Modbus/TCP
over Ethernet to any Modbus client, including DCSs, PLCs,
SCADA systems, and System 1

• 4 channels of vibration inputs (2- and 3-wire velocity and
acceleration sensors and Bently Nevada proximity sensors)

• Up to 4 variables per channel with independent integration
and fi lter control

• Up to 8 pole fi lters on some variables

• 24 bit A/D converters with 25 kHz bandwidth

• 4 Channels of temperature inputs (type E, J, K, and T
thermocouples as well as RTD type sensors)

• 2 levels of alarms — ALERT and DANGER

• 6 confi gurable relays with voting logic

• Buffered transducer outputs — 4 on monitor, 1 on display

• 4 confi gurable 4-20 mA recorder outputs

fact sheet

• Stand alone confi guration software

• Accepts 18 to 36 Vdc power; an external power supply is
available for 110/220 VAC

• Mountable via DIN-rail clip or the bulkhead mounting plate

• Small package – Dimensions (inches):

– Monitor: 7.75 x 5.88 x 2.93
– Display: 7.75 x 5.03 x 1.29
– Monitor with attached Display: 7.75 x 5.88 x 3.85

• Optional fi berglass housing, or steel door (for panel­mount applications), to meet weatherproof installation
requirements and IP65

• Approvals include CSA (Class 1 Div 2 — although the
monitor cannot be installed in Div 1 locations, it will support
transducers installed in Div 1 locations via the use of
isolators and barriers), ATEX (Zone 2), CE, and GOST (IEC Ex)

• Trip Multiply function to prevent unwanted machine trips
during periods of expected high vibration like machine
start-ups
