Abstract:
A pressure and temperature sensor for detecting a pressure and temperature condition in a cavity, comprising a pressure body (16) which co-operates with a sensor housing (12) and which in a mounted condition can be acted upon by a pressure in the cavity and which is intended for transmitting the pressure to a piezoelectrically acting sensor arrangement (30, 32, 34), wherein an electrical signal produced by the sensor arrangement (30, 32, 34) as a reaction to the pressure is passed out of the sensor housing (12) by means of an electrical contact device (48, 50, 52, 54, 56, 58), characterized in that a thermoelectric detector element (40) is fitted in the pressure body (16) and an electrical temperature signal produced by the detector element (40) is passed out by way of the electrical contact device (48, 50, 52, 54, 56, 58); said thermoelectric detector element (40) is located adjacent to said sensor arrangement (30, 32, 34) in said pressure body (16) such that the temperature can be measured at substantially the same location where pressure is measured.
