Abstract:
A sensor module, comprising:an outer module housing having an inlet adapted for fluid communication with a fluid, and having an electrical feedthrough to provide energization contacts, a serial output contact and logic level contacts; a transducer circuit located within the module housing having a sensor for sensing a fluid characteristic, a regulator coupled to the energization contacts, and a transceiver adapted to couple a serial representation of the sensed fluid characteristic to the serial output contact; and a logic circuit coupled to the transducer circuit, wherein the logic circuit has a selectable first mode of operation in which the logic circuit generates ON-OFF logic levels on the logic level contacts, and a selectable second mode of operation in which the logic circuit detects ON-OFF logic levels on the logic level contacts.
