Abstract

A pressure detector, a thermal energy storage vessel, a thermal energy storage system and a method for controlling at least one thermal energy storage vessel are provided. The pressure detector comprises a sealed tube having an internal space, wherein a compressible fluid is located in the internal space of the sealed tube. Moreover, the pressure detector comprises a pressure sensor which is configured to detect a pressure of the compressible fluid in the sealed tube, wherein the pressure sensor is configured to convert the detected pressure into a mechanical and/or electrical signal, characterized in that the sealed tube has a length in the range of ≥ 50 cm. The pressure detector according to the invention allows a simpler, less expensive and less energy consuming determination of an average temperature and of a state of charge of a thermal energy storage vessel than prior art average temperature detectors.
