Stress is one of the important industrial production parameters of the filter pressure annunciator offer, in order to ensure the normal operation of the filter pressure signal production specifications, the pressure must be monitored and controlled. Below is a selection of commonly used terms pressure sensor: standard size in the atmospheric-pressure standard representation, called positive pressure greater than atmospheric pressure; less than atmospheric pressure is called negative. Absolute pressure with pressure for a standard size represents an absolute vacuum. Comparison of the relative pressure of the object (standard pressure) in terms of pressure. Refers to the atmospheric pressure atmospheric pressure. Standard atmospheric pressure (1atm) equivalent to the height of the pressure of 760mm Hg. Vacuum means below atmospheric pressure. 1Torr = 1/760 Pressure (atm). Pressure range is adapted to detect the pressure range of the sensor. When can withstand the pressure when restored to detect pressure, its performance does not drop may be under pressure. When the accuracy of the pressure fluctuation values ??and from a certain temperature (23 ° C) lower, while increasing, decreasing pressure, with the full-scale value of the detected pressure to remove inverted output pressure value obtained by the operation point. Pressure sensor fault prone to go up, the transmitter output is also stagnant. In this case, first check for leaks or pressure port is blocked, if not confirmed, check the wiring and check the power supply filter pressure signal device manufacturers, such as power good output is simple to see if the pressure changes, or look Is there a sensor zero output, without changes in the sensor is damaged, it may be damage to the instrument or other aspects of the problem of the whole system; the pressure signal filter manufacturers, Xinfeng, Puyang filter pressure signal consists of Xinxiang City Xin HSBC sensing purification technology Limited.
