Patent number: 7559228Abstract: A process is provided for measuring a gas concentration with at least one thermal measuring element. The thermal measuring element is operated by pulses. A measured value of the gas concentration in the environment of the measuring element is obtained from the evaluation of the response of the measuring element to at least one single pulse by determining transient states of the thermal measuring element. From this the measured value of the gas concentration in the environment of the measuring element can be derived, during the imposed pulse based on electric measured variables.Type: GrantFiled: August 23, 2007Date of Patent: July 14, 2009Assignee: Dräger Safety AG & Co.

Patent number: 7477395Abstract: A measuring device for determining the concentrations of gases by radiation absorption. The device includes at least one radiation source for generating radiation, a measuring cell, which is arranged downstream of the radiation source and in which the medium to be measured is located and at least one radiation detector, which is reached by the radiation after it has been sent through the measuring cell.

Patent number: 6989549Abstract: A robust gas sensor can be manufactured in a simple manner and at low cost, and have no movable optical components. A measured gas cell (3) has a wall defining a cylindrical space with a measured gas inlet. The measured gas cell (3) is limited in the longitudinal axial direction by a reflective, flat first cover element (1) and by a reflective, flat second cover element (5) arranged at a spaced location from and in parallel to the first cover element (1). The height of the measured gas cell (3) corresponds approximately to 1 to 3 times the diameter of the cover elements (1, 5). The second cover element (5) accommodates a radiation source (6) and two detector elements (23, 24) with at least one measuring detector and one reference detector. The radiation source (6) is arranged displaced by 30% to 60% of the radius of the second cover element (5) from the center of the second cover element (5).Type: GrantFiled: May 5, 2003Date of Patent: January 24, 2006Assignee: Dräger Safety AG & Co.
