NE2042 Eccentricity Monitor

NE2042 Eccentricity Monitor

Equipped with eddy current sensors, it can measure the radial vibration of various rotating mechanical rotors' shafts. Suitable for the system design and use of TSI rotating mechanical devices, it can be widely applied in industries such as power, machinery, chemical, metallurgy, etc. Provide multiple parameter measurements and early fault diagnosis for the safe operation of rotating machinery

1. Functional Description

△Axis eccentricity monitor,Connect two channelsEddy current displacement sensorThere are two ways to measure eccentricity:

1）Key phase method:

Channel B is connected to a key phase sensor, which emits a key phase pulse for each rotation of the shaft, providing time for eccentricity measurement

Intermediate benchmark; Channel A is connected to an eccentricity sensor, which measures only one eccentricity.

This method is suitable for measuring shaft eccentricity of units with large speed variation ranges, such as steam turbines.

2）Keyless phase mode:

Channel A and B are each connected to an eccentricity measurement sensor to measure two eccentricities, without any key phase input.

This method is suitable for measuring shaft eccentricity of units with relatively small speed variation ranges, such as water turbines.

• NE2042Axis eccentricity monitor, based on high-endDSPIntelligent instrument for processors.

The setting of parameters is achieved throughNE2000Configuration software completed.

Normal observation operations can be completed through the dashboard keyboard.

The following functions are provided as standard:

• The instrument functions can be programmed as follows:

Two channels work independently: each channel measures separately, and the two channels are not connected;

Two channel monitoring of the same parameter: Two channels measure the same parameter, which can achieve high reliability measurement and

It has functions such as differential identification;

• Warning of monitoring values, identification of danger exceeding limits, status indication, and output;
• Each channel provides programmable output voltage or current signals to recorders, etc;
• The alarm control output logic of the instrument is programmable:

Or "logicAny channel experiences a super relay action;

The logic of 'and'Both channels experience super relay action;

The four control relay functions of the instrument are programmable and can be selected to interlock or not. Each relay can be configured as a single (or dual) channel warning, danger, and other functions as needed;
