Differential pressure transmitter pressure transmitter is to measure the difference between the two ends of the transmitter absolute pressure transmitter abb, output standard signal (eg 4 ~ 20mA, 0 ~ 5V). Differential pressure transmitter pressure transmitter with the general difference is that they have two pressure ports Smart absolute pressure transmitters, differential pressure transmitters are generally divided into the positive pressure side and suction-side vacuum absolute pressure transmitters , under normal circumstances, the pressure differential pressure transmitter should be greater than the positive pressure side to the suction side of the pressure measurement. Differential pressure transmitter is to measure the pressure differential process pipe or tank in the media, and by converting the data, prescribing to convert differential pressure measurement into a current signal output. Select differential pressure transmitter need to know the following parameters: 1, differential value 2, medium 3, the working medium pressure 4, medium temperature 5, smart or analog honeywell absolute pressure transmitter | absolute pressure transmitter | Hua Hui science and technology provided by the Jinan-Technology Co., Ltd.
