The steam drum – always under pressure
Process heat is usually supplied by steam at different pressures. The required process temperature is regulated via the steam pressure.
Depending on the process temperature, the steam drums operate with pressures up to 160 bar (2320 psig) at a temperature of 400°C (752°F). Such conditions place extremely critical demands on the applied measurement technology.
VEGAFLEX 66 – for extreme conditions
The process seal of the guided microwave instrument is made of ceramic material and thus enables implementation in the high temperature and pressure ranges of a steam drum. In contrast to free radiating radar sensors, a standpipe is not required for the measurement. The sensor can be installed directly in the drum or in the reference vessel.
VEGAPULS 66 – ceramics for high temperatures and pressures
Thanks to ceramic antenna components and a graphite seal, VEGAPULS 66 is well adapted for such extreme applications in steam drums. A standpipe provides optimal signal focussing and eliminates all interference from the measuring environment. The accuracy of the sensor is completely independent of process conditions.
