Vibration Measurement Test System

The in-house system applies controlled airflow and mechanical disturbance at the same time, then records vibration and meter outputs so behavior can be reviewed against a defined test condition.

What the System Evaluates

Observe the meter while the disturbance is known

Static false output

Check whether vibration creates a flow signal with no airflow.

Dynamic variation

Observe frequency and flow output under airflow and vibration.

Mode comparison

Compare signal-processing states under the same program.

Test-System Structure

Airflow, disturbance and sensing on one platform

  • Blower establishes the airflow path
  • Electric regulating valve sets the flow condition
  • Vortex flowmeter is mounted in the test line
  • Vibration motor applies mechanical disturbance
  • Vibration sensor is positioned near the sensing area
  • PLC and software coordinate control and collection

Test Process

A compact controlled sequence

  1. 1. Establish airflow

    Start the blower and set the regulating valve.

  2. 2. Stabilize the point

    Confirm the required flow condition.

  3. 3. Apply disturbance

    Run the vibration motor at the defined condition.

  4. 4. Collect together

    Record vibration, flow and equipment status.

  5. 5. Compare states

    Review static or dynamic behavior against the program.

Controlled Conditions

Data Collected

Relate meter output to the applied condition

The software interface can display vibration frequency, instantaneous flow, accumulated flow, regulating-valve opening and blower status.

Review basis

Vibration + flow + equipment status
