Emerson Universal pH / ORP Sensors
3900,3900 VP Universal pH / ORP sensor uses a double salt bridge reference electrode , which has a strong anti-pollution ability , can work in harsh working environments and extend the life of the sensor. Double salt bridge reference electrode reference electrode can be protected , to avoid erosion by toxic ions - in the process , such as ammonia , chlorine , cyanide or sulfide . Both sensors are used as a Teflon liquid junction ( salt bridge ) , wrapped around pH / ORP glass balls sensitive film .
AccuGlass technology enables glass composition pH glass electrode beyond today's industry standards. AccuGlass glass of the sensor used is glass composition over the years Rosemount Analytical research results , which are shown to extend the life of the sensor. Glass other sensors on the market today is different, the glass can resist rupture, especially in high temperature conditions . Moreover, in the high pH value measurement applications , the glass composition can reduce the measurement error due to the presence of sodium ions produced . In short , AccuGlass glass composition enhances the performance of the sensor , so that a more accurate measurement of pH value , longer life.
3900VP provides waterproof cable connector , you can avoid replacing the sensor cable is twisted phenomenon occurs . Variopol VP multi-pin cable connector is an integral part of the model of the sensor, the use of special need to reprovision VP cable length . Once the cable is installed and connected to the analyzer , places and then replace the sensor , they do not need to replace the cable , without the need for re- wiring analyzer . When the sensor is detached from the process monitoring points , first disconnect the cable , when to avoid demolition of sensors, cables twisted phenomenon occurs .
3900 and 3900VP sensor body using the PPS material, has a strong resistance to chemical corrosion. Completely sealed design eliminates other conventional pH / ORP Sensor design or humidity infiltration occurs problems, and the user does not need to simplify the design structure is filled with electrolyte (KCL), does not require a lot of maintenance diagnostics work program .
Install the sensor is very convenient , offers a variety of installation methods. The first two models are used , the two parts thread design and front-end interface has 1'' MNPT thread and 3/4'' MNPT two sizes , this design concept facilitates the pH and ORP measurement applications , the sensor assembly into the plug-in , immersion or flow-through installation.
Two types of sensors are sensors compound , i.e., the sensor with the measuring electrode , reference electrode and the measuring element , the pipe can be measured in an open container , pH, ORP , or in the oxidation -reduction potential of water-soluble gas tank . 3900 and 3900VP meet most application requirements , and Rosemount Analytical instrumentation matching water quality analyzers and other manufacturers of analysis .
