PH值传感器

pH 值传感器(型号:PH-BTA或PH-DIN)所有传统的pH 计的实验或示范都可以用我们的pH 值传感器。
使用此传感器更可以自动采集数据、作图表、数据分析等功能。
它的典型应用是:研究家庭常见的酸和碱、酸碱滴定、在化学反应、水族箱内光合作用过程中监测pH 的变化、研究酸雨和缓冲液、河流和湖的水质分析等。
威尼尔(Vernier) 有多本实验手册都有各种使用pH 值传感器的实验。

Protocol is widely used to establish master-slave communication between intelligent devices or sensors.A MODBUS message sent from a master to a slave contains the address of the slave,the function code(e.g.'read register'or'write register'),the data,and a check sum(LRC or CRC).The sensor is RS485interface with Modbus protocol.The default serial communication settings is slave address1,modbus rtu,9600bps,8databits and1stop bit.All communication settings can be changed with modbus command,and take effective after re-power up the sensor.Following modbus function code are supported by sensor.Modbus Function Code0x03:used for reading holdingregister.Modbus Function Code0x04:used for readinginput register.Modbus Function Code0x06:used for writing single holding register.Modbus

S40-PH-x-B03INSTRUCTION MANUALCONTROLSOUTPUT LEDIn the normal operating mode indicates the output status (the yellow LED ON indicates the output activation). In the setting phase indicates the setting steps.Please refer to the “SETTING” paragraph for procedure indications during detection or setting phases.POWER ON LEDThe green LED signal indicates the sensor functioning.The LED blinks with the yellow LED if the detection is lacking.TEACH-IN PUSH-BUTTONA long pressure on the push-button activates the self-setting procedure.The REMOTE input allows the external TEACH-IN control.CONNECTIONSREMOTE FUNCTIONThe connection of the REMOTE wire to + Vdc is equivalent to pressing the TEACH-IN push-button.Leave the REMOTE wire unconnected and insulated if not used. If it is connected permanently to 0V, the TEACH-IN push-button functioning is blocked.DIMENSIONSTECHNICAL DATA Power supply: 10 … 30 VDC Class 2 UL508 (reverse polarity protection)Ripple: 10% maxConsumption (output current excluded):35 mA max.

This condition is recommended for opaque object detection. EASYTOUCH ™: (with reflector):Carefully align the sensor and the reflector. The light spot has to be inside the reflector area (see “Installation” section)- Press the TEACH-IN push-button until the OUTPUT LED turns OFF and then release the push-button.EASYTOUCH ™ (without reflector)Before aligning the sensor on reflector (see “Installation” section), set the sensor without reflector, pressing the TEACH-IN push-button, await the blinking of the OUTPUT LED and then release the push-button FINE DETECTIONRecommended for critical detection conditions such as the detection of objects with shiny surfaces: Carefully align the sensor and the reflector. The light spothas to be inside the reflector area (see “Installation” section)- Insert object to detect between sensorand reflector. - Press the TEACH-IN push-button and await the blinking of the OUTPUTLED, without moving the object. Release the push-button.- Remove the object. - Press the TEACH-IN push-button and wait until the blinking OUTPUT LED switch OFF, without moving theobject. Release the push-button. The sensor selects the best operating conditions according to the acquired points and adjusts itself in the DARK mode condition. The acquisition sequence has to be inverted toselect the opposite operating modes.If the OUTPUT LED and the POWER ON LED blinkcontemporarily the detection has failed due to insufficient contrast or setting procedure error. The procedure has to be repeated from the beginning.

pH传感器的校准方法

pH 电极的校准程序:
1.标准溶液的获取:准备两种pH缓冲液,二者间的 pH 值之差一定要大于2pH。
通常最容易获取的pH缓冲液分别是:pH4.00,pH6.86,pH9.18。
一般情况下,每种标准液的体积以100~200ml为宜。
2.清洗,将pH电极从管路上取下,用蒸馏水冲洗
3.长按变送器上Enter键进入CALIBRATE界面(校准菜单),依次按▲▲▲▼按钮进入校准菜单“输入密码输入的密码显示为XXXX”。
4.设定好温度后,按▼键使得变送器界面显示为Standard(标准),按→键进入标准测定。
将探头插入到缓冲溶液中,待读数稳定后,按▲▼键将示数调为缓冲溶液的ph值,按Enter键确定
5.按▼键使得变送器界面显示为Slope(斜率),按→键进入斜率测定。
将探头插入到另一种缓冲溶液中,待读数稳定后,按▲▼键将示数调为缓冲溶液的ph 值,按Enter键确定。
此时,已完成两点校准。
* 为得到最佳校准结果,在稳定期间轻轻搅动缓冲液中的电极5秒钟。

在维护或更换零件之前确保电源断开。
在维护或更换零件之前确保仪表没有外部的压力(比如气压或液压)。
不遵守这些预防措施可能导致人体受伤或损坏设备。
健康与安全在接/拆电源线和传感器信号线的时候,确保仪器已经断电。
pH传感器是用来测量水中pH浓度的,所以取放传感器的时候,请带好合适的PPE。
环境保护此传感器是玻璃结构,它封装有塑料壳体和银/卤化银配件。
使用它的请考虑环境的影响,当到了使用寿命的时候,请根据当地的法律法规进行回收,请勿随意抛弃。
化学品连接到Crius@控制器的传感器会接触到一些危险的化学品,拿放传感器的时候请要万分小心。
注意(CAUTION)当使用此设备时,必须遵守现场的突发情况和个人安全防护准则PPE: 防护服,防护手套,护目镜示例2. pH传感器测量原理当使用电极时,pH被以电位的方式进行测量。
当它与溶液接触的时候会通过pH电极玻璃膜产生一个电势,这个电势变化同pH变化成正比,但是需要一个常数电势来对比这个变化,这个常数电势由内置的参比电极提供。
在酸性或者碱性溶液中,膜片外表面上的电压变化同氢离子变化成等比例关系,如下公式所示:E=总电势差(mv)E0=标准溶液R=气体常数T=绝对温度N=电子数量F=法拉第常数【H+】=氢离子活性技术规格传感器类型: pH2长度: 170mm壳体材料: ,Kynar,316SS接头尺寸:外径最大压力: 100Psi测量范围: 0-14耐压型pH流通池耐压型pH/Orp流通池设计用来允许电极可以在水中被看见,而且不需要减压到大气压。
它可以在线安装,如果压力允许,也能旁通安装。
如果是旁通式安装,那么要确保取样点压力高于插入点的压力以保证有水流流过传感器。
最大的允许压力要低于传感器的额定压力。
3. 设置安装传感器安装pH传感器可以被安装在敞开式单传感器流通池,敞开式双传感器流通池,单传感器密闭式耐压型流通池,单传感器自动清洗装置,双传感器自动清洗装置或者T型接头里,也可以进行浸没式安装(仅限pH3,phH传感器)。
所有情况下,传感器安装都要注意以下几个方面:传感器不能暴露在压力波动超过3Bar(43Psi)环境下。
推荐流量为min,敞开式流通池最小流量要求为mini,自清洗安装推荐流量为8-14l/min推荐温度为0-80℃(pH1,pH2,pH3),0-95℃(pH4),一些传感器带有温度补偿功能。
不允许传感器处于干燥状态。
耐压型密闭式流通池竖直安装取样进口压力高于回水压力确保水流通过传感器。
安装稳定,远离震动源。
压力不要超过传感器的最大允许压力。
请确保有足够的空间来安装、移除电极。

线缆类型和等级-高阻抗电极采用多芯同轴电缆(例如:pH电极)65 传感器调试开始使用前的准备取下电极上的瓶子或者保护帽并用蒸馏水充分清洗。
在运输过程中,气泡可能会跑到电极感应泡里,抓住电极对着光,检查下电极感应泡里是否有气泡,如果里面有气泡,抓住电极向下甩(就像甩体温计一样)来消除气泡。
安装pH传感器可以有几种安装方式可供选择,流通池安装,T型头安装,螺纹头安装等,安装方式在采购的时候就已经确认。
pH3和ph4传感器还能进行浸没式安装。
如果你把不允许浸没式安装的电极(pH1,pH2)进行浸没式安装,可能会导致严重的损坏。
这些传感器配有3/4” NPT公接头或者3/4”BSP公接头来连接支杆,不要使用有弹性的电缆使得电极悬挂着摇晃,不然可能会损坏电极。
校准/标准化(Calibration/Standardising)有两种方法来校准/标准化 pHsense传感器。
第一个是需要最少2到5个pH标准液来”校准(C alibrating)”传感器,第二种只需要一个pH标准液,一个pH试剂或者一个已经校准过的pH传感器。
第二种方法被成为“标准化(S tandardizing)”,因为它并不是一种真正的传感器校准。
pH校准需要设置零点和高点两个参数(offset and slope)。
当pH变化的时候,测量得到的电压也会变化,两者变化关系如下:pH值是7的时候电压为0mV,根据设备的不同,也许在pH为7的时候,测量的电压会稍微有点偏移0mV。
因此,使用pH值6-8的校准缓冲液就非常重要,它可以帮助确保pH为7的时候,电压为0mV。
这就是所谓的”零点(offset”)”.校准(Calibration)使用2到5个标准液可进行pH校准,校准液越多,校准就会越理想。
校准的时候,零点和高点都会被校准。
通常使用3个标准液进行校准就可以,但是在一些pH监测非常严格的应用中,建议进行5点校准。
你可以通过pH传感器预览或者以下方式进入校准功能:从菜单上选择传感器<Sensor>Options Maitenance Calibration根据你选择的传感器类型,你也许需要在选项里先进行温度校准,因为pH值同温度有关。
根据屏幕上的架构和提示,选择”Y e s”来校准温度,温度校准开始后,会进行30秒倒计时。
在倒计时时,控制器会计算传感器信号的稳定性,如果这个过程中,传感器被认为是稳定的,那么会有一个输入真实温度的选项,这个真实温度可用温度计测量样品水温度来获得。
只有在传感器信号是稳定的情况,控制器才允许温度读值被修改。
推荐使用3个或者更多个pH标准液(通常为pH 4,7,10)来校准,然后,也许只需要两个标准液来校准有Crius 控制的pH传感器。
校准温度后,或者在提示你是否校准温度的时候,你选择了“No”,那么你会自动进入校准导引,它会通过以下步骤导引你完成校准:1. 从流通池里取出pH电极2. 把电极放入一个pH标准校准液中,先用那个标准液进行校准并不重要。
3. 按(Next)并确等待知道读数变得稳定,读数稳定后,再按”Next”,30秒倒计时开始,倒计时过程中,控制器从校准中获取数据。
倒计时过程中,如果读数不稳定,那么校准会失败。
4. 系统会自动识别常规标准液(例如:pH=,如果系统识别到标准液,它会要你确认这个是否是标准液,选择”Yes”后,它会自动会有标准液的pH值。
如果不是这个标准液值,那么建议选择”No”然后手动输入使用的标注液值。
如果控制器没有识别到标准液,你会被要求手动输入pH值,pH值输入后,请按”Next”。
见控制器操作手册。
5. 完成后,控制器会要求你重复上面过程进行第二点校准。
6. 输入第二点pH校准值后,控制器会温你是否需要校准另外一点,选择”Yes”会带你再一次进入上面步骤,选择”No”会显示校准结果。
请记住,我们建议至少进行3点校准,如果可能,最好进行5点校准。
只有在“校准结果(Calibration Results)”页面选择“应用(A pply)”后,校准才会被保存。
校准结果页面显示的结果来源于校准标准液,从这些结果获得的计算过的高点和零点,也会显示校准和计算得到传感器健康状况的可信度。
典型零点在-30到+30mv之间,典型的高点在-50和-60之间,如果你的数值偏离了这些范围,请查看”维修导引(Troubleshooting Guide)。
传感器的”健康(H eath)’是通过对比现有高点和期望高点并计算得到的。
正常数值可能是100%,但是如果大于120%,那么可能是使用了不正确的校准标准液,如果小于80%,那么意味着需要清洗电极,如果清洗后,数值还是小于80%,那么就要考虑更换pH传感器了。
