傳輸電纜選用
1、24V電源傳輸電纜的單芯單向電阻應＜20歐姆。DC24V供電時，電纜的最遠傳輸距離如下表：
| 電纜單芯截面積 | 千米電阻 | 最遠傳輸距離 | |
| mm2 | 單向 | 回路 | m |
| 1.0 | 18.1Ω | 36.2Ω | 820 |
| 1.5 | 12.1Ω | 36.2Ω | 1652 |
| 2.5 | 7.4Ω | 14.8Ω | 2057 |
2、在防爆場所，電纜芯線必須采用符合國家標準的銅線，電纜單芯截面積應>1mm2;如需接頭，必須采用防爆接線盒；非鎧裝電纜必須采用穿鋼管防護敷設；鋼管與變送器進線口（G3/4"）可直接套線連接，或加防爆連接軟管；RS-485信號連接必須使用屏蔽雙絞線。
SFD-600與其他廠家氣體變送器產品的性能比較
| 產品名稱 | 探測顯示精度 | 現場液晶顯示方式 | 信號輸出種類 | 故障自診斷技術 | 靈敏度線智能補償功能 |
| 索福達SFD-600XX可燃、有毒氣體變送器 |
一般性可燃、有毒氣體變送器顯示精度為0.1%，探測顯示精度高于行內同類產品。 劇毒類氣體變送器精度為0.01%，探測顯示的高精度業內首創（如：TDI氣體的量程0-0.05mg/m3、砷化氰氣體的量程范圍0-0.03mg/m3）。 |
采用最新多彩液晶，六色顯示。低濃度是為綠色、一段報警時為淺紅色、二段報警時大紅色、故障報警時為黃色。進入菜單參數修改時炫紫色、進入內部參數選項為藍色。幫助您迅速判明現場情況。 |
三種信號輸出： A、4-20mA標準電流信號； B、一段、二段報警點直流驅動信號（驅動容量DC24V/1A）； C、Modbus協議、RS485總線通訊信號。 |
設備發生故障時，顯示屏背景變成黃色，并顯示相應代碼指示故障種類，方便現場儀表維護及使用。 |
基于大多數氣體傳感器的靈敏度線性會隨時間的增加而下降（催化燃燒傳感器每月下降1-2%），我們首創的只需要磁棒調試的傳感器智能線性補償技術，大大提高了氣體探測的客觀性與安全性。 使用高能磁棒進行調試，避免了開蓋、機體按鍵及遙控調試所帶來的受現場環境影響而造成可靠性低、防護防爆性差等缺點。 |
| 其他廠家的可燃、毒性氣體變送器。 | 顯示進度為1%，探測顯示精度一般。 | 普通單色顯示。 | 只能輸出一種或兩種信號。 | 無此功能 | 使用遙控器或開蓋調試，防爆方面存在隱患。 |
