摘要： A hydrogen sensor comprises a housing (10), which is closed off by a membrane (14) that is made of palladium and selectively only pervious to hydrogen. The housing is evacuated and contains a Pirani pressure sensor (22). The membrane (14) and the Pirani pressure sensor (22) are each attached to a carrier (11, 12). Both carriers are joined directly next to one another or kept at a distance by a connection piece (25). The hydrogen sensor has a high sensitivity and a low response time due to the relatively large membrane surface and the low housing volume. It can be produced in a small size and integrated in the handle of a sniffer-type leak indicator.

摘要： A cold cathode pressure sensor (10) comprises a gas-tight housing (12), a test gas inlet (18), an anode (14) and a cathode (16, 17) arranged in the housing (12), and a radiation source (20) directed towards the cathode (16, 17) in order to ignite a cold cathode discharge. The housing (12) is at least in part made of glass. The radiation source (20) is arranged outside the housing (12) and irradiates the cathode (16, 17) through the glass which makes up the housing. The wavelength of the radiation from the radiation source (20) ranges substantially from more than 350 nm to less than 1400 nm.
