The differential pressure transmitter transmits the static pressure difference upstream and downstream to the measuring chamber of the transmitter through a pressure pipe, and then converts it into a standard signal for output. Here, the impulse tube used in the differential pressure transmitter plays a non-negligible role. 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.

Third, the impulse tube of the differential pressure transmitter uses pressure-resistant and corrosion-resistant materials according to the nature and parameters of the measured fluid.

Fourth, the differential pressure transmitter pressure pipe needs to be regularly discharged, because the measurement medium contains dust, oil scale, fine particles, etc. deposited in the pressure guide pipe (or deposited in the pressure taking valve), directly or indirectly affect the measurement of the differential pressure transmitter.

Regularly check the impulse tube of the differential pressure transmitter to ensure the normal use of the differential pressure transmitter and the accuracy of measurement. If you have other questions about differential pressure transmitters, you can consult our technicians, Star Meter has been engaged in the production and development of differential pressure transmitters for many years, with a variety of different types of differential pressure products, Xingyi can also customize the requirements of the transmitter according to user needs.
