Three Ways to Improve pH/ORP Sensor Performance
Process water may be properly treated with the use of accurate pH and ORP readings. It is crucial for operators to have exact control over the performance, reproducibility, and lifespan of the pH/ORP sensors taking those readings. However, taking the measurements is just one step in the procedure. How the pH/ORP readings get sent is where data quality can be significantly impacted. Your pH/ORP Sensor’s performance can be improved with the aid of pH preamplifiers, pH analyzers/transmitters, pH buffer solutions, and pH calibration kits. We’ll discuss the potential benefits of each solution.
pH Preamplifiers Increase Signal Output for pH/ORP Probes
Signal deterioration is a major concern for individuals whose process water pH measurements are being obtained in difficult-to-access locations, such as the top of a big water tank. The raw output of a typical pH/ORP probe is about 59.6 mV/pH. This indicates that hardly any current is used to create the signal. The possibility of signal interference or deterioration increases with the distance between the probe and the transmitter. Experts in water quality frequently use a preamplifier for pH/ORP probes.
So what does the pH/ORP sensor preamplifier option do? The probe’s signal is successfully strengthened by an amplifier to make it more resilient, enabling it to travel farther without deteriorating. The advantages of signal enhancement are frequently worth the extra cost for those with remote water treatment or wastewater applications.
Some preamplifiers do more than merely amplify the pH/ORP Sensor signal. Preamplifiers with SMART capabilities offer extra features like automated pH sensor detection by the transmitter and even built-in calibration data storage. Because of this added capability, operators may quickly replace their outdated sensor with a new one that has already been calibrated. Before being deployed, many sensors might be calibrated in a lab setting. This is especially useful for people whose pH/ORP sensors need to be calibrated frequently, whose sensors are placed in hazardous areas, or whose transmitters are located far from their sensors. Less downtime and more accurate pH/ORP measurements result from this.
pH Transmitters & Analyzers Increase Process Control
Although the words “transmitter” and “analyzer” are frequently used interchangeably, the two devices have a few key distinctions. In order to diagnose issues or further regulate the process, transmitters often need a controller in addition to the digital or analog signal received from the sensor. For instance, the pH, ORP, conductivity, and a variety of other water quality parameters may be measured using the Petron Thermoplast Analytical 5081 transmitter. It makes use of Foundation Fieldbus or HART communication protocols, which enable setup, configuration, reading of process variables, and even problem-solving via a PC or HART communicator.
More advanced pH transmitters like the 5081 have some other characteristics that can be quite useful, such as an explosion-proof shell that enables it to be placed close to the sensor even in the roughest circumstances. Automatic temperature correction and two-point buffer calibration provide accuracy in the field while reducing mistakes. When you acquire your next pH/ORP transmitter, keep an eye out for these qualities.
pH analyzers often have certain crucial extra functions incorporated which allow for better control over operations. For example, the Petron Thermoplast Analytical 1056 Analyzer enables you to calibrate your chlorine sensor, pH/ORP Sensor, and conductivity sensor and even diagnose issues straight from the analyzer. Since pH sensors wander as they become older, this is convenient. In addition to measuring the voltage produced by an object like a pH probe, pH analyzers may also use other parameters to assess the condition of the electrode, including slope, offset, glass impedance, and even reference impedance. Using a configurable temperature coefficient, the Petron Thermoplast 1056 can even account for pH fluctuations brought on by changes in process temperature.
pH Buffer Solutions & Calibration Kits Help Maintain Sensor Accuracy
Maintaining the integrity of your process water or water treatment application depends on the accuracy of your pH sensor. You may calibrate and check the accuracy of your pH sensor using pH buffer solutions and calibration kits. We always propose a two-point calibration. Some pH meters incorporate automated buffer identification to help with calibration, such as the Petron Thermoplast 1056 that was discussed above. The most prevalent buffer standards that are readily available across the world are used, along with their temperature curves. Before finishing the calibration, the pH analyzer will detect the value of the buffer being measured and do a self-stabilization check on the sensor. These kinds of characteristics guarantee that your field measurements will be accurate.
