Precautions for use of seismic pressure gauges
2011-9-10 11:08:16

  1 耐震压力表 必须 垂直 安装 :安装时应 使用扳手旋紧,不应 强扭表壳;运输时应避免碰撞; ( 1 ) The seismic pressure gauge must be installed vertically : it should be tightened with a wrench when installing, and the case should not be twisted strongly; avoid collision during transportation;

2 耐震压力表 使用宜在周围环境温度为-25~55 ( 2 ) The use of earthquake-resistant pressure gauges should be in the ambient temperature of -25 ~ 55 ;

3 使用 过程 如果 因环境温度过高,仪表指示值不回零位或 出现示值超差 ,可将表壳上部 密封橡胶塞剪开,使仪表内腔与大气相通即可; ( 3 ) In the process of use , if the ambient temperature is too high, the indicator value does not return to zero or the indication value is out of tolerance , you can cut off the sealing rubber plug on the upper part of the case , so that the instrument cavity and atmosphere can;

4 使用 工作环境振动频率<25HZ ,振幅不大于 1mm ( 4 ) The vibration frequency of the working environment is less than 25HZ , and the amplitude is not greater than 1mm ;

5 耐震压力表 仪表使用范围,应在上限的1/3 2/3 之间; ( 5 ) The range of instrumentation of the shock-resistant pressure gauge should be between 1/3 and 2/3 of the upper limit ;

6 仪表应 经常进行检定 ,一般 至少每三个月一次; ( 6 ) The instrument should be checked frequently , usually at least once every three months;

7 耐震压力表 在测量腐蚀性介质、 结晶的介质、粘度较大的介质 加隔离装置; ( 7 ) Seismic pressure gauges should be equipped with isolation devices when measuring corrosive media, media that is easy to crystallize, and media with large viscosity ;

8 需用测量腐蚀性介质的仪表,在订货时应注明要求条件。 ( 8 ) Instruments for measuring corrosive media are required, and the requirements should be specified when ordering.
