Abstract: The invention relates to a device for measuring fluid parameters, comprising a Coriolis flow meter. The meter comprises a flow tube and an actuator forcing the flow tube into vibration and/or rotation. Further, the meter comprises a displacement sensor for sensing a displacement of the flow tube. The displacement sensor is arranged for measuring an optical fiber length change.

Abstract: In an arrangement of a traffic infrastructure and an optic sensor system (10, 20), the traffic infrastructure has a traffic carrying surface (51) for providing support of conveyance elements (92) of a vehicle (90), therewith allowing movements of the vehicle over the traffic carrying surface. The optic sensor system (10, 20) comprising an interrogator (10) and at least one fiber optic sensor (20) arranged below the traffic carrying surface that is coupled to the interrogator. The at least one fiber optic sensor (20) comprising an optic fiber (21) with a plurality of optic strain-sensor elements (22) distributed over its length. The plurality of optic strain-sensor elements (22) have mutually different optical characteristics, e.g. a mutually different characteristic wavelength. The interrogator (10) is configured to transmit an optical interrogation signal into the at least one fiber optic sensor, to receive a response optical signal modulated by said fiber optic sensor, and to identify changes in the optical characteristics of the response optical signal resulting from strains induced in said optic strain-sensor elements as a result of a conveyance element (92) of a vehicle (90) moving over the traffic carrying surface (51) across said at least one fiber optic sensor. wherein the at least one fiber optic sensor (20) extends at least substantially according to a straight line in a direction at least substantially parallel to the traffic carrying surface.

Abstract: The airport monitoring system (1) for monitoring an airport territory (5), comprises an airport territory surface and an optic sensor system (70, 72a, . . . , 72e, 100). The airport territory surface has a traffic infrastructure to support conveyance elements of a vehicle (90), e.g. an aircraft or a service vehicle, therewith allowing movements of the vehicle over the airport territory surface.The optic sensor system (70, 72a, . . . , 72e, 100), includes an interrogator module (100) and fiber optic sensors (72a, . . . , 72e) coupled thereto. The fiber optic sensors are arranged below the airport territory surface and have a respective plurality of optic strain-sensor elements (722) with mutually different optical characteristics.The interrogator module (100) transmits optical interrogation signals into the fiber optic sensors and receives respective response optical signals that have been modulated by the fiber optic sensors based on their optical characteristics. The interrogator module (100) identifies changes in the optical characteristics of the received respective response optical signals resulting from strains induced in the optic strain-sensor elements as a result of pressure exerted by a conveyance element (92) of a vehicle (90) on the airport territory surface (51) near a fiber optic sensor.

Abstract: A sensor system (10) and method for monitoring a powertrain (20) having a drive shaft (1). The sensor system (10) comprises an optical fibre (2) with a strain sensitive element (3). According to one aspect, a connection structure (4) is configured to hold at least a part of the optical fibre (2) with the strain sensitive element (3) at a radial distance (R2-R1) remote from the drive shaft (1) for amplifying the strain (S2) on the strain sensitive element (3) with respect to the strain (51) on the drive shaft (1). According to a further aspect, at least three respective lengths of one or more optical fibres follow parallel, e.g. helical, paths with respect to each other to distinguish different strain forces.
