Seal Condition Monitoring: From Sensors to Predictive Maintenance

Many plants still replace them on a fixed schedule or wait until leakage. Status monitoring allows early detection of damage and only interferes when really needed.

The numbers are usually monitored.

• Pressure and temperature of the fluid block or buffer.
• The level of liquid in the container and the speed of depletion.
• The flow of gas in the dry gas.
• Temperature and vibration of the pump.

From data to warning.

Data from the sensor is transmitted to the control system or analytical software.When a parameter exceeds the threshold or trend changes abnormally, the system alerts for planned maintenance instead of emergency repairs.

Benefit is

• Cut off the plan.
• Extend life by intervening at the right time.
• There are data to analyze the cause when the incident occurs.

Attention when launching.

Choose sensors that match the installation location, threshold warnings based on actual data, and train operators to read warnings.
