背景技术Background Art

pH电极又称pH探头、pH传感器,英文名称pH electrode或pH sensor,是PH计上与被测物质接触的部分,用来测电极电位的装置。电位分析法所用的电极被称为原电池。原电池是一个系统,它的作用是使化学反应能量转成为电能。此电池的电压被称为电动势(EMF)。此电动势(EMF)由二个半电池构成。其中一个半电池称作测量电极,它的电位与特定的离子活度有关;另一个半电池为参比半电池,通常称作参比电极,它一般是与测量溶液相通,并且与测量仪表相连。最熟悉也是最常用的PH指示电极是玻璃电极。一套工业在线pH测量系统通常由pH传感器即pH电极、pH变送器、电极护套及电缆等四部分构成。pH electrode, also known as pH probe or pH sensor, is the part of the pH meter that contacts the substance being measured and is a device used to measure the electrode potential. The electrode used in potentiometric analysis is called a primary cell. A primary cell is a system that converts chemical reaction energy into electrical energy. The voltage of this cell is called electromotive force (EMF). This electromotive force (EMF) consists of two half-cells. One of the half-cells is called the measuring electrode, and its potential is related to the specific ion activity; the other half-cell is the reference half-cell, usually called the reference electrode, which is generally connected to the measuring solution and connected to the measuring instrument. The most familiar and most commonly used pH indicator electrode is the glass electrode. An industrial online pH measurement system usually consists of four parts: a pH sensor, i.e., a pH electrode, a pH transmitter, an electrode sheath, and a cable.

pH电极使用时间一般在一年,需要定期更换,需求量大。每一支pH电极制造好后,在出厂之前都要进行检测,要将做好的电极接入测试机器中,放置在三种不同pH值的溶液中进行检测,每次检测时间都需要在一分钟以上,每次检测后都需要对电极头进行清理。现有的pH传感器检验方法多为人工检验,需测试人员对各个传感器进行逐一的测试液测量。并且单一传感器需多个测试液进行检验测量,效率低下,人力成本高。因此,传感器测试方法需要进行改进和优化。The service life of pH electrodes is generally one year, and they need to be replaced regularly, so the demand is high. After each pH electrode is manufactured, it must be tested before leaving the factory. The finished electrode must be connected to the testing machine and placed in three solutions with different pH values for testing. Each test takes more than one minute, and the electrode head needs to be cleaned after each test. Existing pH sensor inspection methods are mostly manual inspections, and testers are required to measure the test fluid for each sensor one by one. In addition, a single sensor requires multiple test fluids for inspection and measurement, which is inefficient and has high labor costs. Therefore, sensor testing methods need to be improved and optimized.

需要一种减少人工参与、大大降低了人工成本与时间成本、有效提高检验效率、风力吹扫减少传感器头残留的pH电极自动检测装置。There is a need for an automatic pH electrode detection device that reduces manual involvement, greatly reduces labor costs and time costs, effectively improves inspection efficiency, and reduces sensor head residue by wind purge.
