Abstract: An insertion electrode device (1) is designed for installing a probe (2) in a medium to be measured, through a receptacle or a fitting (3) in the receptacle. The probe comprises a probe head (10) at an end opposite the measuring end of the probe. The fitting or the receptacle has an internal shoulder (34). In the probe's installed state, the internal shoulder serves as stop for the probe head. A spacer ring (33) and a sealing ring (36) are arranged along a shaft of the probe between the probe head and the internal shoulder. The spacer ring has a profile which, together with the probe shaft, forms a groove (37), In the installed state of the probe, the groove completely accommodates and compresses the sealing ring.

Abstract: A modular force-measuring cell is disclosed which includes a force transducer equipped with sensors that measure changes occurring in the state of the force transducer as a result of a force or temperature. The force-measuring cell also includes a memory module for storing compensation data associated with the modular force-measuring cell. The memory module and at least one converter circuit for the conversion of the signals delivered by the sensors are arranged in a circuit module that is mechanically and thermally coupled to the force transducer.
