The invention relates to a pressure detector with adjustable threshold. The detector comprises pressure transducer means 21 coupled with a manometric diaphragm 11 subjected to the pressure to be detected. The transducer means 21 may consist of differential pressure transducer means, or of absolute pressure transducer means. The transducer means 21 are connected to an electronic processor circuit 3 for comparing the value of the electric signal delivered by the transducer means with at least one adjustable threshold value, a pressure presence signal being delivered. Application to the measurement of relative pressures, differential pressures or absolute pressures. <IMAGE>
