style="font-size:16px;">1）原始值檢查，真實(shí)準(zhǔn)確。</span> </p> <p> <span style="font-size:16px;">2）控壓范圍檢查</span> </p> <p> <span style="font-size:16px;">3）設(shè)定點(diǎn)誤差檢定</span> </p> <p> <span style="font-size:16px;">4）切換差的檢定：在檢定設(shè)定值誤差時(shí)，同一設(shè)定點(diǎn)上切換值的平均值與下切換值平均值之間的差值為開關(guān)的切換差，其值應(yīng)不大于量程的10%，生產(chǎn)廠對切換差有特殊要求的除外。</span> </p> <p> <span style="font-size:16px;">5）重復(fù)性誤差的檢定：在檢定控制器設(shè)定值誤差時(shí)，在同一檢定點(diǎn)通過三次測量中各自測得的上切換之間大差值和下切換值之間大差值，兩者中大者相對于量程的百分比即為控制器的重復(fù)性誤差，其***值不應(yīng)超出開關(guān)的精度等級。</span> </p> <p> <span style="font-size:16px;">6）絕緣電阻的檢定：將控制器電源斷開，用500VDC的絕緣電阻表測量端子與外殼之間，端子之間絕緣電阻≥20MΩ。</span> </p> <p> <span style="font-size:16px;">7）開關(guān)調(diào)整單元封固</span> </p> <p> <span style="font-size:16px;">開關(guān)檢定完后，將開關(guān)定值調(diào)節(jié)裝置封固，以防定值改變。</span> </p> <p> <span style="font-size:16px;">8）觸點(diǎn)電阻的測量≤0.1Ω</span> </p><p> <span

style="font-size:16px;">如果壓力有脈動(dòng)或振動(dòng),需要帶節(jié)流閥用以抑制脈動(dòng)壓力對儀表的損傷。</span> </p> <p> <span style="font-size:16px;">4.帶隔膜的場合</span> </p> <p> <span style="font-size:16px;">測定腐蝕性、高黏度或溫度過高時(shí),需要選用帶隔膜。</span> </p> <p> <span style="font-size:16px;">5.防爆的必要性</span> </p> <p> <span style="font-size:16px;">防爆形式分為隔爆型和本安型,長野產(chǎn)品多數(shù)為隔爆型。</span> </p> <p> <span style="font-size:16px;">6.是否需要帶指示</span> </p> <p> <span style="font-size:16px;">根據(jù)客戶指示。</span> </p> <p> <span style="font-size:16px;">7.接點(diǎn)數(shù)量</span> </p> <p> <span
