ABSTRACT:
An arrangement for monitoring conditions of a fluid comprising a first station incorporating a detector and transmitter assembly including a plurality of condition sensors, each of which is adapted to monitor one or more conditions of a fluid, receipt circuits adapted to receive signals from the sensors, a radio transmitter circuit fed from the receipt circuits; and a second station incorporating a receiver and output assembly including a radio decoding circuit for receiving signals from the transmitter circuit, incorporating a sub-circuit for separating and decoding signals from each of the conditions sensors, and a sub-circuit for converting these signals to a common voltage range, and an output circuit for translating the signal voltages to appropriate signal values for a visual and/or audio output.
