1、仪表应垂直安装于-20℃-55℃，相对湿度不大于85%，无耐腐蚀性气体，无强烈振动的环境中。环境温度（被测介质温度）偏离20℃±5℃时，须考虑温度影响所造成的误差。
2、耐振表安装时应尽量避免表壳、罩圈受力，防止破坏表的密封，造成仪表的灌充液渗漏。
3、在测量液体压力时，仪表应与测压点保持同一水平面，否则应考虑因液位差所产生的测量误差。
4、测量高压气体或剧烈波动的介质压力时，应附加缓冲装置。
5、仪表在测量均匀变化的压力时，工作压力应不大于其测量上限的3/4，测量波动压力时，工作压力应不大于其测量上限的2/3。
6、仪表在使用时应接入24VDC电源。
7、仪表接入控制系统时，其接点装置一般作为主令电气使用，使用时应注意接入仪表的负载功率，电压及电流均不得超过其额定值。
8、仪表设定针的设定，可用一字槽螺丝刀将调节装置的拨片压下后旋转，将设定指针拨至所需控制压力的标度处，耐振表在设定完成后应将调节装置的密封帽旋上，防止仪表内的灌充液漏出。
9、耐振表的外壳是密封的，环境温度变化会造成表壳内部压力产生变化进而影响仪表的精度，因此在使用时应将安装在仪表上部的橡胶塞的突出部分剪去，使仪表内部与大气接通。
10、根据所用仪表的类型按图将相应的接线焊接在航空插头的接线端子上。
1, meters should be installed on the vertical -20 ℃ -55 ℃, relative humidity of not more than 85 percent, Wu Nai corrosive gases, without a strong vibration environment. Ambient temperature (measured medium temperature) from 20 ℃ ± 5 ℃, to take into account the temperature caused by the impact of the error.
2, vibration-resistant forms should be installed to avoid Case, cover laps force to prevent the destruction of the seal table, resulting in leakage of fluid-filled instrument of irrigation.
3, in the measurement of liquid pressure, the instrument should be maintained at the same horizontal plane pressure points, or should be considered due to poor level generated by measurement error.
4, measuring high-pressure gas or sharp fluctuations in the medium pressure, should additional buffer.
5, measuring instruments in the uniform changes in pressure, the pressure should not limit its measurement of 3 / 4, measuring fluctuations in pressure, the pressure should not limit its measurement of the 2 / 3.
6, in the use of instruments should be access 24 VDC power.
7, gauges access control system, its general as the main contact devices to electrical use, the use of instruments should pay attention to access the load power, voltage and current shall not exceed their ratings.
8, the set-setting instrument, the word slot screwdriver can be used to adjust the device for film pressure after rotation, will be required to set guidelines for the control of pressure on the scale, resistant to vibration table should be set after the completion of The seal-conditioning apparatus rotation, the instrument to prevent the leakage of liquid-filled irrigation.
9, vibration-resistant form of the shell was sealed, environmental temperature changes will cause Case internal pressure changes in turn affect the accuracy of instrumentation, the use of instruments should be installed in the upper part of the outstanding rubber Cypriot cut so that the internal instrument Connected with the atmosphere.
10, according to the type of instrument used by the appropriate wiring plans will be welded in the aviation plug on the Connection. |
