WALCHM電極WEL系列產(chǎn)品介紹
Walchem 的 WEL 系列電極是適用于工業(yè)應(yīng)用的高性價比差分 pH 和 ORP 電極
WEL 系列采用模塊化設(shè)計,具有包含電子元件的堅固 CPVC 外殼。 無需工具,即可在數(shù)分鐘內(nèi)輕松連接或更換 pH 和 ORP 柱。電極具有獨特的螺紋互鎖連接和雙 O 形環(huán)密封,確保防水貼合和固定。
可選的差分前置放大器或 4 到 20 mA 變送器,以及溫度補償元件都在外殼中,當(dāng)電極需要更換時不會被丟棄。 電極由與其連接的控制器供電,因此信號始終經(jīng)過前置放大,并且沒有電池會耗盡。
與外殼集成的鈦溶液接地棒可實現(xiàn)差分測量技術(shù)。 這導(dǎo)致電極壽命延長和可靠的測量、雜散電壓和電流或接地環(huán)路問題的抵抗力。
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.
