<p>#CMT# #/CMT# The device has a housing, in which several electrical devices capable of producing heat are arranged, and a temperature measuring arrangement (51) is provided above the devices, which has several temperature sensors (31-42) that are fixed to places in an evenly distributed manner. The places are arranged in a matrix-shape, where the temperature of air or a gas is measured through the sensors. A carrier (30) e.g. printed circuit board, is provided for attaching the sensors, where the sensors are arranged above the housing in longitudinal and transverse rows. #CMT#USE : #/CMT# Used in a low-voltage switching cabinet (claimed). #CMT#ADVANTAGE : #/CMT# The temperature sensors are fixed to places, which are arranged in a matrix-shape, in an evenly distributed manner, where the sensors are arranged above the housing in longitudinal and transverse rows, thus avoiding a time delay between the beginning of the inadmissible heating up of the devices and response of the temperature sensors based on the gas or air mixing within the housing, and hence ensuring a precise detection of the temperature. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a low-voltage switching cabinet. 30 : Carrier 31-42 : Temperature sensors 51 : Temperature measuring arrangement.</p> |
