Abstract: A sensing assembly for use in a piezoelectric liquid level sensor. The sensing assembly comprises: a first piezoelectric sensing module arranged on a magnetostrictive wire and adapted to receive an ultrasonic guided wave signal propagating along the magnetostrictive wire; a second piezoelectric sensing module arranged on the magnetostrictive wire and spaced apart from the first piezoelectric sensing module; and an isolation layer arranged on the magnetostrictive wire between the first piezoelectric sensing module and the second piezoelectric sensing module and adapted to block the ultrasonic guided wave signal from propagating to the second piezoelectric sensing module. Using the sensing assembly, the liquid level of the oil in the tank can be calculated precisely under a strong vibration noise.

Abstract: The present invention discloses a method and system performed by a controller (201) for controlling redundancy functionality by configuring distant located redundant modules in a communication network. The method performed by the controller (201) comprising the steps of: creating (302) a redundant pair over the communication network (206) having a TSN; defining (304) a primary (202) and secondary module (204) based on a transmission of a signal to a first and second module; causing (306) the primary module (202) and the secondary module (204) to create a TSN stream configuration for communicating redundancy information between the primary (202) and secondary module (204); enabling (308) the primary module (202) to communicate (308) the redundancy information periodically over the TSN stream configuration to the secondary module (204); and triggering (312) the secondary module (204) to perform the function of the primary module (202) in response to determining at least one event.
