The invention relates to a fibre-optic accelerometer for determining acceleration along an axis, comprising an optical fibre with a fibre end face and an acoustic membrane with a membrane frame, a deflection mass and connection bridges, the acoustic membrane being designed to reflect, at least in part, a primary radiation from the fibre end face, and the connection bridges connecting the membrane frame and the deflection mass at least at two different axial positions.

Fibre-optic accelerometer

The invention relates to a device for detecting acceleration. The device contains: a frame; a mass; a lever arm connected to the mass, wherein the mass is provided at a first lever position; an optical fiber having a fiber-optic sensor; and a compensation element for disturbance variables, wherein the compensation element for disturbance variables is connected to the lever arm or the mass and wherein the compensation element for disturbance variables is connected to the frame.

The invention relates to an acoustic emission sensor (). The acoustic emission sensor comprises an optical resonator () having a sensor region () configured for reflective operation; an optical waveguide () which is optically coupled to the optical resonator (); a light source () which is optically coupled to the optical waveguide () to apply light to the optical waveguide (); and a detection device () which is optically coupled to the optical waveguide () to detect light from the optical resonator (). The sensor region () of the optical resonator () comprises a coupling device () for mechanically coupling to a solid measurement object (). The coupling device () comprises a first coupling element () for transmitting an acoustic emission signal between the sensor region () and the solid measurement object (), and at least one second coupling element (). The second coupling element () is configured to position the coupling device () on the solid measurement object (), and/or the second coupling element () acts as a filter for the acoustic emission signal.

Acoustic emission sensor having at least two mechanical coupling elements

An explosion-proof thermal imaging system is provided. The system include an explosion-proof housing having a window that is configured to allow thermal radiation therethrough. An infrared camera is positioned within the explosion-proof housing and is disposed to receive and image thermal radiation that passes through the window. An emissivity target is disposed within a field of view of the infrared camera, but on an opposite side of the window from the infrared camera. A temperature sensor is operably coupled to the infrared camera and is configured to provide an indication of temperature proximate the emissivity target.

Explosion-proof thermal imaging system

A thermal imaging system is provided. The thermal imaging system includes an explosion-proof housing with an optical window configured to contain an explosive pressure. The optical window allows electromagnetic thermal energy to pass. A thermal imaging sensor is disposed within the explosion-proof housing. Thermal imaging electronics are coupled to the thermal imaging sensor and configured to provide at least one thermal image based on a signal from the thermal imaging sensor. A lens assembly is disposed at least in front of the optical window external to the explosion-proof housing. A composite optical window for thermal imaging is also provided. In another embodiment, a thermal imaging system includes an explosion-proof housing having an optical window configured to contain an explosive pressure. An infrared (IR) camera is disposed within the explosion-proof housing. A reflector reflects electromagnetic thermal energy to the IR camera, but prevent an object from impacting the optical window.

A thermowell assembly for measuring a process temperature includes an elongate thermowell having a proximal end and a distal end. A bore extends between the two ends with the thermowell assembly configured to extend into a process fluid. An infrared sensor detects infrared radiation from the distal end through the bore of the thermowell and responsively provides a sensor output. A configuration is provided in which infrared radiation received by the infrared sensor from a wall of the bore is reduced and or radiation received from the distal end of the bore is increased.
