The Characteristic Change of Pressure and Differential Transmitter due to a Rapid Change of Ambient Temperature
주위 온도의 급격한 변화에 따른 압력 및 차압 전송기의 특성 변화
Abstract
The pressure and differential pressure(DP) transmitters are used for gas flow rate calculation on the orifice gas metering system. On site, the pressure and DP transmitters are installed in a shelter to diminish the affects of environmental change such as an ambient temperature. But there has been an argument about the effectiveness of the shelter and this brought up the necessity to verify the affects of ambient temperature. These experiments were performed to verify the ambient temperature effects as observing the output of transmitters when the ambient temperature were changed from
