For pressure ranges from 0-1 to 100 PSI that require a wide range of media compatibility, the AST45PT submersible series is an excellent solution to monitor level and temperature for indoor and outdoor applications.  This pressure transducer includes two independent output signals within a single device.  Whether the application requires heating to prevent freezing at a given temperature or constant monitoring to maintain a process, the addition of the temperature output signal provides a simple low cost solution.
