    Abstract: The present invention provides an optical sensor for monitoring current or power in a monitored element of a device such as a bridge-wire or hot-wire of electro-explosive devices. The optical sensor comprises an optical sensor made of semiconductor material. The semiconductor material comprises an absorption edge which is sensitive to a temperature variation. The semiconductor material is for placing in thermal contact with the monitored element of the device, whereby, when the current or power varies in the monitored element, it causes a variation in temperature in the semiconductor element and hence a spectral shift of the absorption edge which can be measured and which is representative of current and power variation.

    Abstract: A diaphragm pressure measuring cell arrangement has a housing body at least partly made of sapphire material and a planar sapphire diaphragm with a peripheral edge joined by a first edge seal to the housing body to form a reference vacuum chamber. An outer surface of the diaphragm is exposed to a medium to be measured. A ceramic supporting body is attached to the back side of the housing body by sealing glass and includes a surface area overhanging that surrounds the housing body to form a first sealing surface. A tubular sensor casing incorporates the measuring cell for mounted the ceramic support body, the casing including an inside second surrounding sealing surface corresponding to the first sealing surface. A metal ring seal is between the sealing surfaces and a pressing member presses sealing surfaces together.
