1、儀表應(yīng)垂直安裝于-20℃-55℃，相對(duì)濕度不大于85%，無耐腐蝕性氣體，無強(qiáng)烈振動(dòng)的環(huán)境中。環(huán)境溫度（被測(cè)介質(zhì)溫度）偏離20℃±5℃時(shí)，須考慮溫度影響所造成的誤差。
2、耐振表安裝時(shí)應(yīng)盡量避免表殼、罩圈受力，防止破壞表的密封，造成儀表的灌充液滲漏。
3、在測(cè)量液體壓力時(shí)，儀表應(yīng)與測(cè)壓點(diǎn)保持同一水平面，否則應(yīng)考慮因液位差所產(chǎn)生的測(cè)量誤差。
4、測(cè)量高壓氣體或劇烈波動(dòng)的介質(zhì)壓力時(shí)，應(yīng)附加緩沖裝置。
5、儀表在測(cè)量均勻變化的壓力時(shí)，工作壓力應(yīng)不大于其測(cè)量上限的3/4，測(cè)量波動(dòng)壓力時(shí)，工作壓力應(yīng)不大于其測(cè)量上限的2/3。
6、儀表在使用時(shí)應(yīng)接入24VDC電源。
7、儀表接入控制系統(tǒng)時(shí)，其接點(diǎn)裝置一般作為主令電氣使用，使用時(shí)應(yīng)注意接入儀表的負(fù)載功率，電壓及電流均不得超過其額定值。
8、儀表設(shè)定針的設(shè)定，可用一字槽螺絲刀將調(diào)節(jié)裝置的撥片壓下后旋轉(zhuǎn)，將設(shè)定指針撥至所需控制壓力的標(biāo)度處，耐振表在設(shè)定完成后應(yīng)將調(diào)節(jié)裝置的密封帽旋上，防止儀表內(nèi)的灌充液漏出。
9、耐振表的外殼是密封的，環(huán)境溫度變化會(huì)造成表殼內(nèi)部壓力產(chǎn)生變化進(jìn)而影響儀表的精度，因此在使用時(shí)應(yīng)將安裝在儀表上部的橡膠塞的突出部分剪去，使儀表內(nèi)部與大氣接通。
10、根據(jù)所用儀表的類型按圖將相應(yīng)的接線焊接在航空插頭的接線端子上。
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. |
