| 关于电容式压力变送器电气盒如何拆卸介绍： How to disassemble the electric box of capacitive pressure transmitter is introduced. 1、拧下接线端子侧的表盖就可触及信号端子（电源端子），他们牢牢地固紧在电气盒，不要拆卸，否则两腔室间的密封就被破坏，从而破坏了腔室的隔爆结构，达不到隔爆额定值。 1. The signal terminal (power terminal) can be touched by unscrewing the cover on the side of the connection terminal. They are firmly fastened to the electric box and do not disassemble it. Otherwise, the seal between the two chambers will be destroyed, thus destroying the explosion-proof structure of the chamber and failing to reach the explosion-proof rating. 2、拧下电路两侧的表盖，就可以触及智能电子部件和显示表头，应养成一种良好习惯；先断开电源，再去下电路侧的表盖。 2. Turn off the covers on both sides of the circuit, and you can touch the intelligent electronic components and the display head. You should form a good habit. First disconnect the power supply, then remove the covers on the side of the circuit. 3、拧下线路板固定的M4螺钉，并用此M4螺钉拧在放大板对应的M4螺孔中，就可以拔下放大电路析。 3. Unscrew the M4 screw which is fixed on the circuit board and screw it into the M4 screw hole corresponding to the amplifier board, so that the large circuit analysis can be pulled out and lowered. 4、效验电路板，应先排齐零位和量程调节螺钉，使其上的一字槽垂直于效验板，就可以方便地取下效验板了。 4. In the validation circuit board, the zero-position and range-adjusting screw should be aligned first so that the slot on it is perpendicular to the validation board, so that the validation board can be easily removed. 5、取下铭牌，拆下装在凋零、调零程螺钉上的开口档圈，就可以取下零位和量程和调节螺钉。 5. Take off the nameplate, remove the open gear ring mounted on the withered and zero-adjusting screw, and you can remove the zero position and range and adjusting screw. |
