SM39PWB-CY differential pressure transmitter is used to measure the level, density, pressure, and flow of liquid, gas or steam, and then convert it into 4mA~20mADC HART current signal output. It can also communicate with HART handheld terminal for parameter setting, process monitoring, etc.<\/p>\n\n\n\n

      Range limit<\/strong><\/p>\n\n\n\n

      It can be adjusted arbitrarily within the upper and lower limits of the measuring range.<\/p>\n\n\n\n

      It is recommended to select a range code with the lowest possible turndown ratio to optimize performance characteristics. Zero setting<\/strong><\/p>\n\n\n\n

      The zero point and span can be adjusted to any value within the measuring range in the table, as long as: the calibration span \u2265 the minimum span<\/p>\n\n\n\n

      Installation location affects<\/em><\/h3>\n\n\n\n

      The change of the installation position parallel to the diaphragm surface will not cause zero drift. If the installation position changes more than 90\u00b0 from the diaphragm surface, a zero position effect within the range of <0.4kPa will occur, which can be corrected by adjusting the zero. No range effect.<\/p>\n\n\n\n

      Output<\/em><\/h3>\n\n\n\n

      Two-wire system, 4mA~20mADC, optional HART output digital communication, optional linear or square root output. Output signal limit: Imin=3.9mA, Imax=20.5mA<\/p>\n\n\n\n

      Response time<\/em><\/h3>\n\n\n\n

      The amplifier component damping constant is 0.1s; the sensor time constant is 0.1s to 1.6s, depending on the range and range ratio. The additional adjustable time constant is: 0.1s to 60s. The impact on non-linear outputs (such as square root function) depends on this function and can be calculated accordingly.<\/p>\n\n\n\n
