Pressure sensor at ordinary times we are generally not used alone, buy commonly when pressure sensor with the goods and only certificate and instruction manual, it is rare to see other attachments, but when pressure sensor used in the following situations should add additional devices. Let's say the attachment.
In order to keep the pressure sensors are not affected by erosion or measured medium viscosity is too large, the influence of crystallization, the installation of isolation device should be; In order to ensure that sensors are not affected by the dramatic change of measured medium or pulse pressure, the influence of adding buffer. Especially in the steep fall in pressure surge and pressure, the easiest way to make the pressure sensor damage to scrap, even spring tube burst, leakage phenomenon; In order to ensure the instrument is not affected by vibration, pressure sensor shall be equipped with damping device and fixing device; In order to guarantee the weighing sensor is not affected by high temperature of measured medium, should add liquid-filled pipe bending device; Special special sensor, and he is forbidden, it is strictly prohibited in the no special reliable device to measure, more it is strictly prohibited to use the general pressure sensor as a special medium pressure measurement; Pressure sensors for new purchase, before installation, must conduct metrological verification, to prevent shock pressure sensor transit damage accuracy, damage, or other factors.
For us to understand the purpose of these attachments selection pressure sensor is a function of at ordinary times, when we in the use of pressure sensors at ordinary times meet these situations can know to choose the corresponding accessories.
