The differential pressure transmitter transmits the static pressure difference between the upstream and downstream to the measuring chamber of the transmitter through the impulse tube, and then converts it into a standard signal for output. Here, the impulse tube used in the differential pressure transmitter plays a role that cannot be ignored. Therefore, how to correctly protect the impulse pipe is also particularly important. First, the impulse tube of the differential pressure transmitter needs to be kept at the same temperature or in an environment with a small temperature gradient. Second, the length of the impulse tube of the differential pressure transmitter is not easy to be too long. Thirdly, the impulse tube of the differential pressure transmitter uses pressure-resistant and corrosion-resistant materials according to the properties and parameters of the measured fluid. Fourth, the impulse pipe of the differential pressure transmitter needs to be drained regularly, because the measurement medium contains dust, oil scale, fine particles, etc. deposited in the impulse pipe (or deposited in the pressure valve), which directly or indirectly affects the measurement of the differential pressure transmitter. Regularly inspect the impulse tube of the differential pressure transmitter to ensure the normal use of the differential pressure transmitter and the accuracy of the measurement. If you have other questions about differential pressure transmitters, you can consult our technicians, Star Meter has been engaged in the production and research and development of differential pressure transmitters for many years, with a variety of different types of differential pressure products, Xingyi can also customize the transmitter according to user needs.
