A subsea housing assembly, in particular for a subsea sensor, includes a first housing portion and a second housing portion. The first housing portion includes a first electrical connection for data communication and the second housing portion includes a second electrical connection for data communication. A wall provides separation between the first housing portion and the second housing portion of the subsea housing. An inductive coupler, that includes a first coupling section disposed in the first housing portion and a second coupling section disposed in the second housing portion, is provided. The inductive coupler is configured to provide inductive coupling across the wall for providing at least a data communication between the first and second electrical connections.

An improved method of sealing a window into an aperture in a body uses a lubricant comprising polymer particles suspended in a volatile, low viscosity, low surface tension carrier fluid. The carrier fluid is applied to one or both of the sidewalls of the window and aperture, and the window is pressed into the aperture such that the carrier fluid evaporates, leaving the polymer particles to fill interstitial surface voids, while enabling the sidewall of the window to make intimate mechanical contact with the sidewall of the aperture. While having broader application, the present disclosure finds particular utility in optical characterization techniques based upon the Raman effect and fluorescence probes used in process monitoring and control.

An instrument enclosure includes top and bottom sections, the bottom section having a first part fastened to a second part, and hinges hinging the top and bottom sections to enable the top section to rotate between a close positioned and an open position. When closed, the instrument enclosure defines an enclosed space suitable for receiving a field instrument. The bottom section may be fastened to a standpipe or to a bracket fastened to the standpipe. The bottom section may define an opening configured to receive the standpipe and/or an opening to receive process line tubing carrying process line signals to the field instrument. The field instrument may be affixed to an end portion of the standpipe received in the enclosed space, removably attached to an interior of the instrument enclosure, or affixed to a mounting plate attached to the standing pipe.

A sensor module for a rail vehicle contains a box-like module housing with a housing wall having a front opening. It further has one or more environment sensors arranged in the module housing for acquiring environment data that can be perceived through the front opening. Moreover, it contains one or more front windows, which have in each case one window pane, which closes the front opening. As a result, the integration of environment sensors into rail vehicles, in particular for high-speed operation, can be optimized. A rail vehicle ideally contains such a sensor module.

A seal for a meter ring includes a sealing section and a connecting portion. The sealing section is configured to block transmission of light from a first portion of a meter cluster to a second portion of the meter cluster. The connecting portion extends from the sealing section and is configured to couple the sealing section to a meter ring.

A sensor-cluster apparatus includes: sensors configured to detect and collect external environment information, the sensors including one or more kinds of sensors; a body member having one surface onto which the sensors are mounted; a case on which the body member is fixed, the case including: an inner space in which the body member is mounted; and an opening defined in one surface thereof exposing the inner space, the sensors are exposed through the opening; and a cover configured to open and close the opening of the case, wherein, the sensors are configured to be detached from the body member through the opening of the case with the body member fixed to the case.

A device cover including an upper portion, a lower portion, and a fastener is disclosed. The upper portion includes a top surface, upper sidewalls extending downwardly from a perimeter of the top surface, and a transparent section carried by the top surface. The lower portion includes a lower surface and lower sidewalls extending upwardly from a perimeter of the lower surface. The fastener has a first side connected to the upper portion and a second side connected to the lower portion. An attachment portion is positioned on an end portion of the fastener and connected to a portion of each the upper portion and the lower portion. The first and second sides of the fastener are cooperatively configured to secure to one another. The upper and lower portions are cooperatively adapted to form a void and to operably carry a device within the void.
