Patent ID: 7272525

Claim:
An apparatus for use in monitoring a property of a fluid in a fluidic system, the apparatus comprising a plug adapted for removable engagement with the fluidic system, and a flexural resonator mounted on a first surface of the plug and having a sensing surface for contacting the fluid, the plug being adapted for electrical communication between the flexural resonator and one or more of a signal processing circuit, or a data retrieval circuit, one or more conductive paths extending through the plug and providing electrical communication between the flexural resonator and one or more contacts on a second surface of the plug, such that a removable sensor subassembly can be interfaced with the flexural resonator through the one or more contacts, and a temperature sensor mounted on the first surface of the plug, and one or more conductive paths extending through the plug and providing electrical communication between the temperature sensor and one or more contacts on the second surface of the plug.
