7BN1642壓力變送器具有工作可靠,性能穩定,安裝使用方便,體積小,重量輕,性能價格比高等特點.能在各種正負壓力測量中得到廣泛應用.
7BN1642壓力變送器采用進口擴散硅或陶瓷壓阻傳感器作為壓力檢測元件,傳感器的信號經高性能電子放大器轉換成4-20mA或0-10mA統一輸出信號.

壓力變送器7BN1642?主要性能指標:

◆ 精度等級:   0.25級基本誤差±0.25%

               0.5級基本誤差±0.5%

◆ 非線性誤差: 0.25級≤±0.25%FS

               0.5級≤±0.5%FS

◆ 輸(shu)出(chu)特性:   兩線制(zhi)4-20mA輸(shu)出(chu)的品(pin)種,標準供(gong)電(dian)(dian)(dian)(dian)DC24V,負(fu)(fu)載電(dian)(dian)(dian)(dian)阻(zu)(zu)大于600Ω時(shi),每(mei)增(zeng)加50Ω需(xu)增(zeng)加1V供(gong)電(dian)(dian)(dian)(dian),但zui高供(gong)電(dian)(dian)(dian)(dian)極限為DC45V.當需(xu)要超過DC24V供(gong)電(dian)(dian)(dian)(dian)時(shi),輸(shu)出(chu)回路(lu)應避免長期工作在零負(fu)(fu)載電(dian)(dian)(dian)(dian)阻(zu)(zu)狀態,必要時(shi)可在輸(shu)出(chu)回路(lu)中串入電(dian)(dian)(dian)(dian)阻(zu)(zu)以降低輸(shu)出(chu)功率管的功耗(hao).零負(fu)(fu)載電(dian)(dian)(dian)(dian)阻(zu)(zu)時(shi)zui底(di)供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓DC12V。
