BENTLY 3300/20 DUALTHRUST POSITION MONITOR

BENTLY 3300/20 DUALTHRUST POSITION MONITOR

DESCRIPTION

The BENTLY 3300/20 DUALTHRUST POSITION MONITOR (Bentley 3300/20 Dual Thrust Position Monitor) is a monitoring system developed by Bently Nevada, Inc. specifically designed for the continuous measurement and monitoring of the axial position of shafts in relation to the axial clearance of machines.

Main functions and features

Dual-channel monitoring: the monitor has two independent channels, capable of monitoring the same collar or two different positions of the shaft at the same time, improving the accuracy and reliability of monitoring.

Thrust Bearing Failure Detection: It is able to detect the failure of thrust bearing at an early stage, which is of great significance to ensure the safe operation of the equipment.

High-precision measurement: Measurement of thrust position is achieved by measuring the gap voltage through the proximity probe, which has high precision and stability.

False alarm protection: As sensor failures (e.g. out-of-range clearance) can be misinterpreted as thrust position movement, leading to false thrust alarms, it is recommended that two proximity probes are used for monitoring and configured for AND voting (i.e. both sensors must reach or exceed the alarm set point at the same time in order to activate the alarm relay) to prevent false alarms.

LED Indicators: Each channel is equipped with one green LED indicator and one red LED indicator to show the operational status of the monitor, sensors and field wiring as well as alarm status.

Installation and Configuration

Mounting probe: It is usually necessary to install an axial probe to directly monitor the thrust ring to ensure the accuracy of the measurement results.

Configuration Parameters: Users can configure the monitor's parameters according to actual needs, including alarm setpoints, channel selections, and so on.

Debugging and calibration: After installation and configuration, debugging and calibration are required to ensure that the monitor can work properly and accurately reflect the actual state of the equipment.

Application Scenarios

BENTLY 3300/20 DUALTHRUST POSITION MONITOR is widely used in a variety of industrial fields that require high-precision thrust position monitoring, such as power generation, petrochemical, steel and so on. It is especially suitable for those critical equipments which require very high requirements on the operation status and health condition of the equipments, such as steam turbines, compressors, etc.

Maintenance and upkeep

Regular Inspection: Regularly inspect the monitor and probe to ensure that they are in good working condition.

Cleaning and maintenance: Clean and maintain the monitor and probe to avoid the accumulation of dust and dirt affecting the measurement accuracy.

Replacement of damaged parts: If the monitor or probe is found to be damaged or malfunctioning, the damaged parts should be replaced in time to ensure the normal operation of the equipment.
