A moisture measuring device for gases, in particular compressed gases, compressed air and the like, for moisture content detection in a gas supply system, includes a gas sampling input for the test gas which is connected to the gas supply system. A separate gas channel used only for the moisture measurement branches off from the gas sampling input. The separate gas channel is connected with a measuring cell in which a dew point sensor is arranged. A drying cell with a drying agent is connected downstream of the measuring cell. The drying cell is substantially hermetically sealed against the outside environment. Lastly, the output side of the drying cell is connected to an outlet channel leading to the outside environment. A gas supply system may have the form of a compressed gas system, a compressor station, a storage system and the like.

A test method for a semiconductor device comprising a substrate wafer in which an element is formed and a material through which an infrared ray can be transmitted and a package having airtight space between a cap wafer which is provided being opposite to the substrate wafer, and which includes an applying water process in which a semiconductor device is exposed to high moisture atmosphere and a leak discrimination process in which an infrared ray from the semiconductor device is detected and leak of the package is discriminated based on absorption of the infrared ray by water molecules.

A process transmitter includes a transmitter housing and a liquid detector coupled to the transmitter housing. The liquid detector includes a temperature sensor configured to generate signals indicative of a presence of liquid within the transmitter housing. The process transmitter also includes a controller coupled to the liquid detector configured to receive the generated signals, determine the presence of liquid within the transmitter housing based on the received signals, and generate an output indicative of the determined presence of liquid within the transmitter housing.

A moisture detecting bleeder material includes a fiberglass material and a moisture absorption indicator material. The moisture absorption indicator material undergoes a color change from a first color to a second color when exposed to moisture. The color change thermally irreversible a temperature of 450 F.

An industrial process vessel insulation monitoring system for monitoring an insulated section of a process vessel containing a process material includes one or more condition sensors and a controller. The condition sensors are configured to sense at least one environmental condition, such as temperature, humidity, moisture level, and/or chemical composition, and generate condition outputs that are indicative of the corresponding sensed condition. The controller is configured to detect at least one section condition relating to the insulated section based on the condition output, and generate condition information relating to the at least one detected section condition. Examples of the section conditions include a thermal resistance of an insulation of the insulated section, damage or degradation to an insulation of the insulated section, corrosion of the process vessel at the insulated section, conditions that promote corrosion of the process vessel, and moisture intrusion to the insulation.
