相对压力变送器PFA

微分 低压 高静压

高精度差压变送器的测量范围从1毫巴到30巴。可靠的压力变送器适用于您的工业仪器。压差(dp)是两个压强之间的压强差。压差传感器比较两种压力:低压侧参考压力(LP)和高压侧压力(HP)。压差传感器将压差转换成电子信号。对于应用在非常低或非常高的温度，压差传感器可以配备一个或两个膜片密封。测量压差，例如监测泵，例如测量压降，例如监测过滤器堵塞，连续测量液体或气体液位，例如压力罐，传感器单元的高压(HP)端测量压力。传感器单元的低压(LP)侧测量气体大气压力，高压和低压侧之间的压力差允许发射机计算液位。密度必须恒定，以保证测量的准确性。测量液体(液体、气体、蒸汽)的体积或质量流量。 In this last case, it is associated with a deprimogen which creates a differential pressure according to the flow of a fluid. To measure an interface or a density. Numerous applications: flow, level, filtration, density, interface. Robust design withstands high static pressure. Improved accuracy compared to using two relative pressure sensors. Measures very small measuring ranges.
