HPM129A-121/123 High Temperature Melt Pressure Transmitter instrument can be used in Melt-blown fabric production procedure to measuring and controlling pressure of high-temperature articles. It also applied in the fields of chemical fibers, plastics and rubber or high-temperature resistant fluid. By assimilating advanced technologies of
similar international products and using imported raw materials and key elements, the instrument is characteristic of stable operation, reliable performance, high accuracy, strong output signal, excellent dynamic performance and slight high-temperature resistant zero drift. This series Transducers can joint with our Intelligence digital display
pressure sensor instruments to control and measure pressure.Connecting screws and outgoing connectors are all universal.
