On-Line Measure System of the Temperature in the Synthetic Ammonia Tower Based on the LM75A Temperature Sensor

Abstract

The multi-layer temperature was measured in the synthetic ammonia tower by the LM75A temperature sensor, which can exactly adjust temperature in the synthetic ammonia tower, and improve the synthetical rate of ammonia, except for which, reduce cost. The hardware and software system of on-line measuring temperature in the synthetic ammonia tower was designed and debugged. The result was that this system can very good realize the multi-layer temperature measuring in the synthetic ammonia tower, and exactly adjust the temperature of the synthetic ammonia tower in time, at the same time the temperature can exactly display on LCD screen.
