ZJS Intelligent Vibration Swing Monitor

1. Overview                                               

The ZJS vibration swing monitoring device is a dual-channel intelligent digital instrument with a single-chip microcomputer as the core processor. The instrument is connected with the eddy current displacement sensor to monitor the radial displacement in the X and Y directions of the main shaft of the hydro-generator unit online; it can be connected with the low-frequency vibration sensor to monitor the vibration value in the vertical and horizontal directions online. The instrument has dual-channel digital display, analog quantity, switch quantity and communication output.

2. Features

The intelligent monitoring device with single-chip microcomputer as the core processor has strong applicability.

Two-channel two-level alarm value can be set independently.

Press the button to set the vibration/swing monitoring method.

It can switch to display the gap voltage between the eddy current sensor and the spindle to determine the accuracy of the installation gap.

With power-off protection, automatic memory function.

Perfect system self-check function.

The working power supply (+24V) of the transmitter can be provided.

3. Technical performance                                       

Display mode: dual LED highlight digital tube display is clear and intuitive.

Input signal: when used for vibration monitoring: it can receive signals from two channels (horizontal/vertical) vibration sensors, when used for swing monitoring: it can receive signals from two channels (X/Y) of eddy current sensors.

Measuring range: 0~1.00mm (swing is the symmetrical displacement in X/Y direction)

Measurement accuracy: 0.01mm

Alarm output: Contact form: normally open contact.

Contact capacity: 5A/AC220V, 2A/DC30V.

Alarm setting: The second-level alarm value can be arbitrarily set between the upper and lower limits of the range.

Working power supply: switching power supply AC85~265V, DC110~340V.

The instrument provides the transmitter: DC24V power supply, the transmitter does not need an external power supply.

Environmental conditions: Temperature: Working temperature: 0℃~40℃.

Storage temperature: -25℃~+70℃.

Relative humidity: ≤85%RH.
