US Classification:

34053922

Abstract:

An exemplary apparatus includes a sensor array configured to sense a gas stream temperature, pressure, and humidity. The sensor array includes a plurality of sensors, each configured to sense at least one of the gas stream conditions. The apparatus further includes an electronic control unit comprising a memory storage device, a condition evaluation module, a display module, and a wireless transmission module. The memory storage device stores a plurality of condition parameters, each condition parameter corresponding to one of the gas stream conditions. The condition evaluation module is configured to determine if one of the sensed conditions violates one of the corresponding parameters, and is further configured to output a warning command in response to the determining. The display module is configured to display information relating to at least one of a sensed condition and a condition parameter. The wireless transmission module is configured to wirelessly transmit data relating to at least one of the warning command and one of the sensed conditions.
