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.

60M100 Overview

The 60M100 Condition Monitoring System has been specifically designed for continuous permanent monitoring of wind turbine generator sets.

The system is designed to monitor equipment where reliability and availability are critical.

The 60M100 system is designed to monitor the basic characteristics and components of a wind turbine generator, including.

Tower sway

Main bearings

Main rotor

Gearboxes

All internal bearings

All bearing engagement

Debris monitoring

Generator bearings

Generator Grounding

Digital Communications

The 60M100 system has digital communications capabilities to connect to ADAPT software using a proprietary prtocol over an Ethernet connection.

The 60M100 system transmits data via Ethernet TCP/IP. You can monitor the values and status of process and control and other automation systems.

The 60M100 system provides extensive communication capabilities for all monitored values and statuses.

It can be integrated with process control and other automation systems that use Ethernet TCP/IP communication functions.

It allows Ethernet communication with other 60M100 systems and system software.

Supported protocols include

Modbus/TCP

The industry standard Modbus protocol over TCP.

The 60M100 supports both server and client modes.

System Features

The 60M100 monitors up to 150 static variables and generates high resolution waveform data and trend lines.

The 60M100 is a powerful and versatile condition monitoring system.

It provides basic monitoring functions and advanced signal processing and rules in a compact, rugged unit.

The module modulates the input signal to make a variety of measurements and compares the modulated signal with user-programmable alarms.

The 60M100 system is capable of receiving input signals from different types of sensors.

It supports up to 12 dynamic channel inputs, two key signals and digital communications. Channels 1 to 10 are connected to a 2-wire ICP type accelerometer.

Channels 11 and 12 can be configured to interface with 2-wire ICP-type sensors or 3-wire proximity probes.

Each dynamic channel can be configured independently with flexible signal processing options.

The Keyphasor channels can be connected to 3-wire proximity probes or other externally powered speed sensors.

The module enhances monitoring of rolling bearing machinery and gears with 24-bit analogue/digital conversion and a 40 kHz bandwidth design.

The 60M100 system is not a replacement for hard-wired safety systems, nor is it a replacement for standard systems that collect data on wind turbine operation.

Description

The Bently Nevada Seismic Probe Velocity Sensor System is designed to measure absolute vibration (relative to free space) of a bearing housing, enclosure, or structure.

The two-wire system consists of a transducer and appropriate cable.

The Seismoprobe series of velocity sensors is a two-wire design using moving coil technology.

It provides a voltage output proportional to the vibration velocity of the sensor.

Moving coil sensors are less sensitive to www.cniacs.com shock or pulse excitation than solid state velocity sensors.

Solid-state velocity sensors are themselves accelerometers with embedded integrated electronics.

Moving coil sensors are less sensitive to shocks or pulsed excitation and are a good choice for some applications.

Portable measurement applications are facilitated by the fact that no external power supply is required.

Available Types

There are two types of seismic probe velocity sensors:

l 9200: The 9200 is a two-wire sensor suitable for continuous monitoring or periodic measurements with test or diagnostic instruments.

When ordered with the optional integrated cable, the 9200 offers excellent corrosion resistance without the need for an additional cable.

l 74712: The Model 74712 transducer can be used for continuous monitoring or periodic measurements with test or diagnostic instruments.

l 74712: The 74712 is the high temperature version of the 9200.

Interconnecting cables can be used to connect 9200 and 74712 sensors to other instruments.

Other Instruments. These cables are available in various lengths, with or without stainless steel armour.

When ordering the 9200 and 74712 Seismic Probe Velocity Sensors, expect approximately six weeks lead time.

Approximate lead time is six weeks. Lead times vary depending on component availability and configuration.
