Bently Nevada Machinery Condition Monitoring 1900/65A General Purpose Equipment Monitor

Description

The 1900/65A General Purpose Equipment Monitor is designed for the continuous monitoring and protection of equipment used in a variety of applications and industries.

The monitor is cost effective and is the ideal solution for general purpose machines and processes that benefit from continuous monitoring and protection.

Inputs

The 1900/65A provides four sensor inputs and four temperature inputs.

Each sensor input can be configured by the software to support 2-wire and 3-wire accelerometers, velocity sensors or proximity sensors.

Sensors or proximity sensors. Each temperature input supports E, J, K, and T type thermocouples as well as 2-wire or 3-wire RTDs.

Outputs

The 1900/65A provides six relay outputs, four 4-20 mA logger outputs, and one dedicated buffered output.

The 1900 Configuration Software allows the user to configure the relay contacts to be determined for any channel or combination of channels,

alarms, and hazardous conditions, and provide data on any logger output for any variable from any channel.

Dedicated buffered outputs provide signals for each sensor input.

The Modbus gateway option allows the monitor to provide static variables directly to any Modbus client,

status, event list, time and date information directly to any Modbus client, including Distributed Control Systems (DCS),

Supervisory Control and Data Acquisition (SCADA) systems, Program Control and Data Acquisition (DCS) systems, Data Acquisition Systems (DCADA).

(SCADA) system, programmable logic controller (PLC), or System 1 software.

The monitor uses internal counters and a Modbus client/master time base to generate time and date information.

The 1900/65A supports Modbus communications via Ethernet and a software configurable RS232/485 serial port.

Configuration

Users can create configuration files using software running on a laptop or PC.

The user can create a configuration file using software running on a laptop or PC and download the file to the monitor over the built-in Ethernet connection to define monitor operation and Modbus Gateway register mapping.

The 1900/65A can permanently store configuration information in non-volatile memory, which can be uploaded to a PC for changes.

Display Module

The 1900/65A supports an optional display/keypad for viewing channel information or making minor configuration changes.

This allows the 1900/65A to operate as a stand-alone software package. If desired, the user can mount the display up to 75 metres (250 feet) away from the monitoring module.

SPECIFICATIONS

Inputs

Sensor Inputs

Channels 1 through 4 can be configured by the user to accept inputs from acceleration, velocity, or displacement sensors.

Inputs for Acceleration, Velocity, or Displacement Sensors

Sensor Channel Types

The channel type defines the processing function applied to the input signal and the type of variable or measurement value derived from that input.

The channel type also defines the type of sensor that must be used. Sensor channel types include

Acceleration or Reciprocating Acceleration

Velocity or Reciprocating Velocity

Radial vibration (shaft vibration)

Thrust (axial displacement)

Position

Velocity

Acceleration and Reciprocating Acceleration Channel Types

The Acceleration channel type and Reciprocating Acceleration channel type support dual and triple wire accelerometers.

The Reciprocating Acceleration channel type has Timing Determination Channel Failure disabled.

Acceleration Variables and Reciprocating Acceleration Variables

The Acceleration Variable and Reciprocating Acceleration Variable are measurements that are filtered and processed from the raw sensor signal.

The Acceleration channel type and Reciprocating Acceleration channel type can continuously process up to four variables per channel. Up to four variables per channel can be processed continuously.

Vibration : Up to three bandpass filtered amplitude measurements.

Acceleration Envelope:

The user can apply the acceleration envelope algorithm to an acceleration or reciprocating acceleration variable.

Bias Voltage: The user can assign a sensor bias voltage value to any variable.
