1. Improving the Reliability of Melt Pressure Detection by Redundancy Method Because of the high power of the melt booster pump, the high temperature and pressure of the transported polyester melt, the measurement of the outlet pressure of the melt booster pump is required to be reliable and accurate, and safety accidents due to the failure of the pressure gauge are not allowed. Using the redundancy method, two pressure transmitters are installed at the outlet of the melt booster pump to measure
