The invention relates to a cold cathode pressure sensor comprising a gastight housing having a test gas inlet, an anode and a cathode arranged in said housing, and a radiation source directed to said cathode for igniting a cold cathode discharge. Said housing is at least partly made of glass. Said radiation source is arranged outside said housing and irradiates said cathode through the housing glass. Said radiation source substantially emits a radiation of a wavelength of more than 350 nm and less than 1,400 nm.
