摘要：A gas blender comprising a plenum for mixing gas, at least one flow valve, an oxygen nsor, a microprocessor, and driver circuits. The inlet gas port is adapted to be in fluid communication with a supply of a desired gas and the flow valve is dispod between the supply of gas and the inlet of the plenum. At least one driver circuit adjusts the flow valves to change the gas flow rate therethrough and, accordingly, the rate at which gas enters into the plenum. The oxygen nsor measures the percentage composition of oxygen exiting from, or inside, the plenum and generates an output bad on the measured percentage composition of oxygen. The microprocessor controls the percentage composition of oxygen exiting from the plenum and is electrically coupled to the output of the oxygen nsor. The microprocessor compares the output of the oxygen nsor to a predetermined level of oxygen and generates a respon signal bad on the comparison, which is communicated to the driver circuits. The driver circuits are electrically coupled to both the microprocessor and the flow valves and adjust the flow valve so that the percentage composition of oxygen exiting the plenum is maintained at the predetermined level. The blender of the prent invention may also include a pressure nsor in fluid communication with the
