GF+SIGNET 2720系列前置放大器
+GF+SIGNET 2720系列前置放大器 (已停產(chǎn)，替換型號為2760系列）
3-2720 前置放大器
Signet2720前置放大器是應(yīng)用中所必須的，它可以防止公共工業(yè)環(huán)境中的各種電磁噪音，對PH/ORP電極有較微弱的輸出信號的干擾。Signet2720旋轉(zhuǎn)鎖前置放大器，在傳感器測量點獨特的安裝的。它就*大限度地保護長度可達120m的加長電纜。獨特的旋轉(zhuǎn)鎖設(shè)計簡化了安裝和維護，它能使電極能快速連接和拆卸。放大器的CPVC本體，在浸入式和在線應(yīng)用中都不易破損，延長了工作壽命。如果需要遠(yuǎn)程前置放大器（如：罐溫>80℃）或接其他生產(chǎn)商的電極，可用Signet2721遠(yuǎn)程前置放大器。

| 2720/2721 Preamplifier |
 |
|
Pre-amplification is required to protect the output signal of pH & ORP electrodes from a wide variety of electromagnetic interference common in industrial environments. The Signet 2720 Preamplifier is installed locally, at the sensing point, to maximize this protection while allowing cable extensions up to 120 m (400 ft). Signet's unique twist-lock design simplifies installation and maintenance by providing for the quick connection and disconnection of electrodes. And the CPVC body is virtually unbreakable for extended service life in both submersible and in-line applications. If remote pre-amplification is necessary (e.g., tank temperature > 80° C), or if connecting to another manufacturer's electrode, use the Signet 2721 Remote Preamplifier.
