Martens 傳感器 GTL737 溫度傳感器

Martens 傳感器 GTL737 溫度傳感器 Martens of the GHM GROUP

夾緊溫度傳感器GTL737用于在沒有介質接觸的情況下測量溫度。
測量端直接位于管壁上，并通過管道上的夾緊式適配器固定。 該測量過程提供高精度和快速響應時間，這通常優于具有介質接觸的測量原理。

●通過夾緊式適配器進行簡單安裝
●沒有媒體聯系的過程連接
●即使不使用熱化合物，也
●響應時間快
●更換/清潔傳感器，無需中斷過程
●帶集成變送器的Pt100傳感器
●變送器可通過GTL配置工具或按鈕進行編程
●LCD現場顯示，背景照明
●輸出4..20 mA，2線連接
