压力变送器使用注意事项
Precautions for the use of pressure transmitters
1：切勿用高于36V电压加到变送器上，导致变送器损坏；
1: do not use higher than 36V voltage added to the transmitter, causing damage to the transmitter;

Imported food, casual snack
2：切勿用硬物碰触膜片，导致隔离膜片损坏；
2: do not touch the diaphragm with hard objects, causing the diaphragm to be damaged;
3：被测介质不允许结冰，否则将损伤传感器元件隔离膜片，导致变送器损坏，必要时需对变送器进行温度保护，以防结冰；
3: the measured medium is not allowed to freeze, otherwise it will damage the sensor diaphragm, causing damage to the transmitter, the necessary temperature protection of the transmitter, in order to prevent them from freezing;
4：在测量蒸汽或其他高温介质时，其温度不应超过变送器使用时的极限温度，高于变送器使用的极限温度必须使用散热装置；
4: in the measurement of steam or other high temperature medium, the temperature should not exceed the limit when using the temperature transmitter, temperature transmitter used must be higher than the limiting radiation device;
5：测量蒸汽或其他高温介质时，应使用散热管，使变送器和管道连在一起，并使用管道上的压力传至变压器。当被测介质为水蒸气时，散热管中要注入适量的水，以防过热蒸汽直接与变送器接触，损坏传感器；
5: measurement of steam or other high temperature media, should use the cooling tube, the transmitter and the pipeline connected together, and the use of pipeline pressure to transformer. When the measured medium is water vapor, the heat pipe to inject the right amount of water, to prevent direct contact of superheated steam and transmitter, sensor damage;
