GF+SIGNET 2720系列前置放大器
+GF+SIGNET 2720系列前置放大器 (已停产，替换型号为2760系列）
3-2720 前置放大器
Signet2720前置放大器是应用中所必须的，它可以防止公共工业环境中的各种电磁噪音，对PH/ORP电极有较微弱的输出信号的干扰。Signet2720旋转锁前置放大器，在传感器测量点独特的安装的。它就*大限度地保护长度可达120m的加长电缆。独特的旋转锁设计简化了安装和维护，它能使电极能快速连接和拆卸。放大器的CPVC本体，在浸入式和在线应用中都不易破损，延长了工作寿命。如果需要远程前置放大器（如：罐温>80℃）或接其他生产商的电极，可用Signet2721远程前置放大器。

| 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.
