A pressure sensor suitable for use in automotive applications is provided to sense the pressure of a pressurized fluid medium and generate an electrical signal representative of the sensed pressure on a set of electrical contact members. A main housing body has a fluid supply opening adapted to conduct a pressurized fluid medium into the housing body. A pressure measuring cell is provided including a plastic measuring cell housing and an electric pressure sensor arranged on the plastic measuring cell housing. The pressure measuring cell is disposed on the housing body of the pressure sensor apparatus adjacent the fluid supply opening so that at least part of the electric pressure sensor is acted upon by the pressurized fluid medium. A reinforcement plate member is adapted to engage a back side of the pressure measuring cell to hold the pressure measuring cell in place relative to the main housing body against the pressure of the pressurized fluid medium. At least two electrical conductors are integrally molded into the plastic measuring cell housing and extend completely through the plastic measuring cell housing and through the reinforcement plate member to form first and second sets of electrical contacts on opposite high and low pressure sides of the plastic measuring cell housing to enable electrical connection to the electric pressure sensor disposed in the main housing body.
