5.8.2 Seal layout of temperature sensor

The sealing of the temperature sensor is generally carried with wire seals.

In this section the sealing methods used by Elster GmbH for the standard temperature
sensors are illustrated as examples. Other variants of seals are possible depen ding on the
combination of temperature sensor and thermowell.
