Maxwell vacuum gauge PM-4, the force measured since the instrument, Maxwell vacuum gauge PM-4 sales force measured by Shanghai Automation Instrumentation Co., Ltd. Maxwell vacuum gauge PM-4, the force measured since the instrument, Maxwell vacuum gauge PM-4 sales force measured in Shanghai Automation Instrumentation Co., Ltd. (www.licesh.com) launched this new upgrade, above pictures for reference only, please Dial telephone or pictures on this page, for the latest information, contact: Hua powder. 4, the vacuum gauge at the end of the measurement, the application of vacuum hose clamps and clamping gas isolation using the vacuum system. This can keep the vacuum cleaner McNamara, within the mercury vacuum gauge PM-4, but also to avoid a vacuum gauge is removed when the separation Maxwell vacuum gauge PM-4 sales, atmospheric vacuum gauge to make a strong impact crusher. If you do not remove the vacuum gauge should be stopped after mechanical vacuum pump, be sure to mechanical pump and vacuum system gas line is disconnected, and the mechanical pump into the atmosphere inside in order to avoid mechanical pump oil back into the vacuum system and vacuum gauge by oil pollution. Vacuum gauge is based on the principle of making a variety of vacuum pressure is used to measure the size of the vacuum sensor. According to People's Republic of China National Standard (GB7665-87), the definition of the sensor (Transducer / Sensor) is: can feel the provisions are measured in accordance with certain rules and converted into the device or devices available output signal. Sensor is a certain degree of accuracy in the measurement object is converted to determine a corresponding relationship with whom to facilitate the application of a physical quantity measuring device. Gauge is a certain precision will have to determine the vacuum pressure into the relationship between voltage and current values ??of the measuring device is a sensor Maxwell vacuum gauge PM-4 Main, in a system function Maxwell vacuum gauge and a thermometer PM-4 images, magnetometers, light meter, and so on, there is no essential difference.
