压力变送器是一种常用的压力仪表，广泛应用于工业、化工、电力、电子、船舶、机床、石油等行业。压力变送器在使用过程中也会产生损坏的问题，损坏压力变送器一般有以下原因:
Pressure transmitter is a commonly used pressure instrument, which is widely used in industry, chemical industry, power, electronics, shipping, machine tools, petroleum and other industries. Pressure transmitter will also cause damage in the process of use. There are generally the following reasons for damage to pressure transmitter:
1:在压力传递过程中，应注意以下几点，变送器与热管之间的连接不应泄漏。管道必须保持干净，沉积物会从管道中冒出来，损坏传感器膜。*在使用前，如果阀门处于关闭状态，则应小心、缓慢地开启阀门，以免被测介质直接冲击传感器膜片，损坏传感器膜片;
1: In the process of pressure transmission, we should pay attention to the following points. The connection between transmitter and heat pipe should not leak. Pipeline must be kept clean, sediment will come out of the pipe and damage the sensor film. * Before use, if the valve is closed, the valve should be opened very carefully and slowly, so as not to directly impact the sensor diaphragm and damage the sensor diaphragm.
2:在测量蒸汽或其他高温介质,应使用散热器管、发射机和管在一起,并使用管路压力变化,在使用之前,如果阀门关闭,使用,应该小心,慢慢打开阀门,为了避免被测介质直接影响传感器隔膜,以破坏传感器膜片;
2: In measuring steam or other high temperature medium, radiator tube, transmitter and tube should be used together, and the change of pipeline pressure should be used. Before using, if the valve is closed and used, it should be very careful to open the valve slowly, in order to avoid the medium directly affecting the sensor diaphragm, so as to destroy the sensor diaphragm.
3.严禁用硬物接触隔膜，造成隔离膜损坏;
3. It is strictly forbidden to use hard objects to contact the diaphragm, causing damage to the diaphragm.
4:被测介质不允许冻结，否则会损坏传感器元件的隔离膜片，导致发射机损坏。必要时对发射机进行温度保护，防止冻结;
4: The measured medium is not allowed to freeze, otherwise the isolation diaphragm of the sensor element will be damaged and the transmitter will be damaged. If necessary, the transmitter should be protected by temperature to prevent freezing.
5:在测量蒸汽或其他高温介质时，其温度不应超过使用中变送器的极限温度，超过极限温度的压力变送器必须使用散热装置;
5: When measuring steam or other high temperature medium, its temperature should not exceed the limit temperature of the transmitter in use, and the pressure transmitter exceeding the limit temperature must use a heat sink device.
6:请勿使用高于36V的电压加到发射机上，以免损坏发射机;
6: Do not use a voltage higher than 36V to add to the transmitter, so as not to damage the transmitter;
