SC24V-ALN26-225電極傳感器 SC24V、SC24V-ALN26-120、SC24V-ALN26-225 Features
• VP connector
• Sterilizable pH sensor
• No reference electrode or junction
• Maintenance free pH sensor
• No diffusion = high stability SC24V Differential pH sensor
The SC24V it a differential pH sensor. This means that the reference is not a （liquid） junction but a glass sensor which does not respond to pH changes （within the applicable range of the sensor）. Therefore the sensor is truly maintenance free and the output voltage of the sensor depends only on the salt concentration of the process. The sensor responds to pH changes rather than analyzes the accurate pH value. In that sense it is best to describe the sensor as pH control sensor rather than pH measuring sensor. A pH sensor measures the voltage that the pH membrane measures as function of the pH value of the process sample.
This voltage is then compared with the mV output of a reference cell that is independent on the pH value of the sensor In most pH control applications the salt concentration is rather constant, so the output of the SC24V differential sensor is only dependent on the pH of the process. A rule of thumb is that a change in salt concentration of +/- 25% has an effect of less than 0.1pH on the pH reading. 廣州技創電子設備有限公司優勢代理銷售日本橫河YOKOGAWA全系列儀表！ 日本橫河YOKOGAWA 指針電表、數字萬用表、兆歐表/絕緣電阻表、鉗型電流表、便攜式校驗儀、功率計、分流器/變壓器、有紙記錄儀、無紙記錄儀、混合記錄儀、記錄儀配件、便攜式記錄儀、數字調節儀、信號轉換器/互感器、閥門定位器/轉換器、溫度變送器、壓力變送器、電磁流量計、渦街流量計、手操器、數字溫度計、數字照度計、氧分析儀、電導率儀、PH/ORP計/電極、探頭/傳感器/電纜、DCS卡件/模塊/PLC、分流器/變壓器/電阻器、張力計 |
