WALCHM电极WEL系列产品介绍
Walchem 的 WEL 系列电极是适用于工业应用的高性价比差分 pH 和 ORP 电极
WEL 系列采用模块化设计,具有包含电子元件的坚固 CPVC 外壳。 无需工具,即可在数分钟内轻松连接或更换 pH 和 ORP 柱。电极具有独特的螺纹互锁连接和双 O 形环密封,确保防水贴合和固定。
可选的差分前置放大器或 4 到 20 mA 变送器,以及温度补偿元件都在外壳中,当电极需要更换时不会被丢弃。 电极由与其连接的控制器供电,因此信号始终经过前置放大,并且没有电池会耗尽。
与外壳集成的钛溶液接地棒可实现差分测量技术。 这导致电极寿命延长和可靠的测量、杂散电压和电流或接地环路问题的抵抗力。
Walchem’s WEL Series electrodes are cost-effective differential pH and ORP electrodes for industrial applications
The WEL Series are modular in design with a rugged CPVC housing that contains the electronics. pH and ORP cartridges can easily be connected or replaced in minutes without tools. The cartridges feature a unique threaded interlock connection and a double o-ring seal, ensuring a watertight fit and secure seating at all times.
The optional differential preamplifier or 4 to 20 mA transmitter, and temperature compensation element are in the housing, and are not thrown away when the electrode needs replacement. The electrode is powered by the controller it is connected to, so the signal is always preamplified and there are no batteries to go dead.
A titanium solution ground rod integral to the housing enables the differential measuring technique. This results in prolonged electrode life and reliable measurement, resistance to stray voltages and currents or ground loop problems.
