Working Principle of U7139-002BA-2W0000

The U7139-002BA-2W0000 composed of a pressure sensitive elements, a conditioner circuit, a linear amplifier circuit, and 4-20mA current output circuit. The first working principle of this series pressure transmitter is that when there is a pressure difference between the entry side and the output side, it can create a difference between two sides of the pressure sensing components, and this difference is proportional to the measured pressure difference. Eventually, the diaphragm on the pressure inlet is bent or stretched to adjust the pressure inside the pressure chamber of the conditioner and the surrounding pressure connected with the conditioner, thus outputting a signal linear to the pressure difference between the two sides. The second working principle is that the output signal is amplified by the linear amplifier circuit, outputted to 4-20mA current output circuit, and eventually sent out as a 4-20mA current signal to fulfill an analog output.

In summary, U7139-002BA-2W0000, this is a pressure transmitter with wide application area, small size and high accuracy features. And its working principle is quite simple as well. After understanding its application field and working principle, you certainly can use it in the right situation to contribute to industrial production and processing.
