KVS Intelligent Vibration Pendulum Monitoring Instrument

Product Overview: 　

Vibration and runout are important indicators for evaluating the quality of unit operation and are important parameters affecting the safe operation of hydroelectric generators. The KVS series intelligent vibration and runout monitoring instrument is an intelligent dual channel digital instrument with a super large scale microprocessor as the core. The instrument is connected to an eddy current sensor to monitor the radial vibration of the main shaft X and Y directions of the hydroelectric generator unit online, and connected to a low-frequency vibration sensor to monitor the vibration of the vertical and horizontal channels online. The instrument also has analog, switch, and communication signal outputs.

Technical indicators:

Functional features: (The following description is for a single channel, with two channels having the same function and being independent of each other)

Input: velocity displacement sensor

Alarm setting: There are two levels of alarms: "Warning" and "Danger"

Panel display: (via the conversion switch on the front panel) vibration value, alarm setting value

Panel indicator: When the sensor is normal, the OK light is on; When the sensor malfunctions, the OK light goes off;

After troubleshooting the sensor, the OK light flashes for 5 seconds and then turns on

When the "warning" alarm appears, the warning indicator light (yellow LED) lights up; Press the reset button and the alarm indicator light will turn off

When the "danger" alarm appears, the danger indicator light (red LED) lights up; Press the reset button and the alarm indicator light will turn off

Attention: When the alarm indicator light is on, it does not equal the output of the alarm relay contact. Only when the alarm reaches the set delay time will the alarm be triggered

Only output and maintain.

Alarm delay: Alarm delay relay contact output function increases alarm reliability; The delay time is selected by the userInstrument calibration and alarm equipment

Fixed value change: When replacing sensors or measuring materials, or when calibration is required after prolonged use;When the alarm value needs to be changed,

Just open it beforeThe panel can be operated.

Alarm output: "Warning" and "Danger" alarms, both of which are relay contact outputs (constant power loss)

Alarm multiplier: When the unit starts and stops, press the alarm multiplier button to avoid false alarms caused by excessive vibration during the unit's start and stop process

(Unless otherwise specified by the user, it is set at 2 times when leaving the factory)

Signal output: Record output of 1-5V, 4-20mA

The raw signal of the sensor is buffered and amplified before being output from the rear panel terminal for diagnostic analysis

Indicator self check: The LED indicator lights up within 10 seconds of power on for self check

Power on alarm delay: The instrument automatically shields the alarm relay within 15 days of power on to avoid false alarms during the power on process

Interference suppression: When peak interference occurs, the alarm relay is automatically shielded to avoid false alarms

Alarm relay status: self-locking or self resetting

Input: Vibration speed sensor 2 points
