A sensor apparatus for determining and/or monitoring a process variable of a medium in a containment includes: a crystal body including at least one defect; a magnetic field system for producing a magnetic field in the region of the crystal body and in the region of the medium within the containment, wherein the crystal body and the magnetic field system are arrangeable from the outside at a wall of the containment; a detection unit for detecting a magnetic field-dependent, fluorescent signal from the crystal body, wherein the detection unit has an excitation unit for optical exciting of the defect and a detector for detecting the fluorescent signal; and an evaluation unit for ascertaining at least one piece of information concerning the process variable based on the fluorescent signal.

Quantum sensor

A method for monitoring the condition of a coil, wherein the coil is part of a device for determining at least one process variable of a medium in a container, includes applying an electrical excitation signal to the coil and receiving an electrical reception signal from the coil, determining a first value for the reception signal at a first predefinable measurement time, comparing the first value for the reception signal at the first measurement time with a reference value, and determining a condition indicator for the coil on the basis of the comparison. Disclosed also is a device that is designed for carrying out the disclosed method.

Monitoring the condition of a vibronic sensor

The present disclosure relates to a pH-sensor for determining and/or monitoring a pH value of a medium, having a sensor unit with a wall in contact with the medium, and at least one pH-sensitive material, which has at least one spin state that changes as a function of a pH value. The at least one pH-sensitive material is arranged in or on a region of the wall in such a way that the at least one spin state is subjected to a change in the pH value of the medium. The pH-sensor also includes a spin-sensitive unit, which is configured to detect a variable associated with the at least one spin state, wherein the spin-sensitive unit is arranged in an environment of the at least one pH-sensitive material such that the spin-sensitive unit is subjected to a change in the spin state of the at least one pH-sensitive material.
