Application

A large power plant needed a redundant overfill protection system for four of its boilers. Planning and implementation of the project were carried out by the engineering firm Wolter & Dros B.V. The heat exchangers, which were already equipped with mechanical float switches, have an output of 6000 kW each. The biggest danger in this application is the occurrence of hydraulic shock. A good overfill protection system must be able to survive such abrupt pressure surges unscathed. To provide twofold safety, the sensor should be based on a completely different measuring principle. By using two different measuring principles, systemic flaws can be eliminated.

VEGASWING 66

The solution

VEGASWING 66 is the ideal solution for this application.
With a temperature range of -196 ... +450° C and a maximum pressure of 160 bar, it’s just perfect for this demanding measurement task.
From the wide range of options the operator chose a robust aluminium housing and a standard, size G1 threaded fitting. Together with a relay output, the VEGASWING 66 sensor fit like custom made into the existing power plant systems.

This solution increases not only the reliability of the system but also its safety margin. If one of the two overfill protection systems fails, continued, trouble-free operation of the boiler is guaranteed.

User benefits
