  1. application<\/em><\/li>\n<\/ol>\n\n\n\n

    The diaphragm box of the double-flange remote diaphragm pressure transmitter is used to prevent the medium in the pipeline from directly entering the pressure sensor component of the transmitter. Silicone oil and other filling liquids are used to transmit pressure between it and the transmitter.<\/p>\n\n\n\n

    SM39PWB-SFLYC double flange remote diaphragm pressure transmitter is used to measure the level, density and pressure of liquid, gas or steam, and then convert it into 4mA~20mADC HART current signal output. It can also communicate with HART handheld terminals to set parameters and monitor processes.<\/p>\n\n\n\n

    The measuring range of SM39PWB-SFLYC double flange remote transmission diaphragm pressure transmitter (when not migrated) is 0-1kPa~2MPa, and the rated pressures of the remote transmission flanges are: 1.6\/4MPa, 6.4MPa 10MPa, 150psi, 300psi or 600psi.<\/p>\n\n\n\n

    1. How it works<\/em><\/li>\n<\/ol>\n\n\n\n

      The SM39PWB-SFLYC double flange remote transmission diaphragm pressure transmitter is composed of the SM39PWB-CY series differential pressure transmitter and the remote transmission flange with capillary installed by welding. Its working principle is the same as that of the CY series differential pressure transmitter (CY series differential pressure transmitter technical specification), but the pressure transmission path is slightly different: the pressure acting on the remote transmission flange side first passes through the diaphragm and filling liquid on the remote transmission flange, and then through the capillary to reach the corresponding positive and negative sides of the measuring sensor.<\/p>\n\n\n\n

        The minimum range of the remote transmitter should be the larger value of the minimum range in Table 1 and Table 2. The adjusted range shall not be less than the minimum range.

          The damping constant of the amplifier component is 0.1s; the time constant of the sensor and remote flange is 0.2s to 6s, depending on the sensor range, range ratio, capillary length, and filling fluid viscosity. The additional adjustable time constant is: 0.1s to 60s.<\/p>\n\n\n\n

                The transmitter body can be directly fixed in any position. The best state is to make the process flange axis in a vertical state, and the position deviation will produce a correctable zero offset. The electronic case can be rotated up to 360\u00b0, and the positioning screws can fix it in any position. The remote flange is connected to the matching flange that meets the ANSI\/DIN standard. The matching flange should be equipped with a soft gasket and mounting bolts and nuts (the user can choose the mounting bolts and nuts). For double-sided flange remote transmitters, the capillary component and the remote flange should only be installed in the same ambient temperature. The minimum bending radius of the capillary is 75mm, and winding is strictly prohibited!<\/p>\n\n\n\n
