産品詳情

産品特點

KBA127礦用攝像儀用于Zone01環境Ⅰ類氣體組以下（典型氣體爲甲烷、瓦斯等），適用礦井下各種需要監控的場所。

攝像儀采用光端機、網絡攝像機以光纜或視頻電纜傳輸監控信號。

KBA127礦用攝像儀內置超低照度攝像機或者紅外高清網絡攝像機，能在光線較暗或者無光的條件下獲得良好的監視效果。

不鏽鋼構造，能在0℃到+40℃溫度條件下長時間穩定工作。

供電電壓範圍85VAC~265VAC。

視窗采用特殊的鋼化平板玻璃制作，在堅固耐用的同時，保證了畫質的清晰。

以太網信號傳輸提高了系統應用的靈活性；光傳輸在保證信號質量的同時，使得傳輸距離有效提升。

‘I thought they were just some sort of grass,’ he said. ‘The woods are covered with them. Will you show them to me when they are all out?’ A VILLAGE ON THE TOKAIDO. A VILLAGE ON THE TOKAIDO. "But what is it for?" gasped Arthur. Arthur caught his breath. "No women?" A little ornament fell from the table by Countess Lalage's side and a cry escaped her. Lawrence looked up in mild surprise. "Are you not going to speak first?" Lawrence asked. Fifth.—Shrinkage; the allowance that has to be made for the contraction of castings in cooling, in other words, the difference between the size of a pattern and the size of the casting. This is a simple matter apparently, which may be provided for in allowing a certain amount of shrinkage in all directions, but when the inequalities of shrinkage both as to time and degree are taken into account, the allowance to be made becomes a problem of no little complication. We are getting the most dreadful lessons in philosophy--all of After the delay, which in India is a matter of course, the caravan set out—the last to go; for during the past three months no European had[Pg 247] crossed the pass, and in consequence of misunderstandings with some of the rebel tribes to the north, even the natives were prohibited henceforth from going to Cabul. The sun had now gotten so high that Shorty could hardly pretend to sleep longer. He gave a tremendous yawn and sat up. The older man regarded him attentively, the other sullenly. Now, out on a far planet there's a strange race. Maybe you've heard about them, because they work for us, they help get us the metals we need to keep going. They're part of the big line of supply that keeps us all alive, you and me both.
