ABSTRACT:
Pressure detector circuits are disclosed in which a pressure sensor is connected to an amplifier having an output signal. A three state comparator compares the output signal with a first reference voltage to provide a comparison output which is fed back in a feedback path to another input of the amplifier through a low-pass filter. A first controllable circuit source connected in series with the first reference resistor are connected in the feedback path to detect an open or short circuit condition of the pressure sensor. Another controllable current source connected in series with a second reference resistor and a voltage divider are also provided in the feedback path which in combination with the first current source detect breaks and short circuit conditions of the pressure sensor. A switch connected is parallel to a high value resistor having a resistance higher than that of a low value resistor in the low-pass filter is also provided in the feedback path.
