Different Types And Uses Of pH Sensor

A pH sensor is among the essential tools for measuring the pH of water. The said sensor can detect the quantity of alkaline and acid in water and other solutions. When appropriately used, a durable pH sensor can guarantee the security and quality of the products and the processes involved in a wastewater or manufacturing facility.

The standard pH scale is characterised by a set ranging from 0 to 14. A pH of seven indicates that a substance is impartial. Substances with a pH value greater than seven are thought to be more alkaline, whereas those with a pH level of less than seven are considered more acidic.

The distinction between alkaline and an acidic substance is critical for any business that uses a cooling tower, boiler, production processes, swimming pool control, or other monitoring systems. The person’s body has a usual pH level of 7.4 that must be maintained to operate effectively. If the body’s structure has become too acidic or too alkaline, it will seek to come back to a neutral position.

Different Types Of pH Sensor

A pH sensor will keep pH levels at the optimal level for the procedure. Several kinds of pH sensors are available for your liquid measurement application, including laboratory pH sensors, combination pH sensors, differential pH sensors and process pH sensors.

1.    Laboratory pH Sensor

It uses combined pH sensor systems built to house plastic bodies and 12mm glass. These small sensors are ideal for light applications such as science and research, pool monitoring, and environmental sampling. These sensors are incredibly versatile. If you’re looking for a laboratory sensor, the junctions, wires, and sensor fill can all be customised to meet your specific application requirements.

2.    Combination pH Sensor

A combination pH sensor was the most commonly utilised sensor obtainable, attributed to its ability to serve as the basis for developing research lab sensors and procedure sensors. This electrochemical sensor has a reference electrode and a monitoring electrode. While the reference electrode concentrates on maintaining the signal stable when recording the pH level, the measuring electrode detects any latest changes in the pH level.

It is mainly used in developing research labs and process sensors. The greatest characteristic of this type of sensor is that it is a highly flexible innovation. The two electrodes can perform the essential functions of reading and assessing the pH levels of water, ensuring fast and accurate measurement results.

3.    Differential pH Sensor

They function slightly differently than combination pH sensors in that they have three electrodes. The first two electrodes are equivalent to those seen in combination sensors; however, the third is a metal ground electrode that can aid in source fouling prevention. Because of its third electrode, this type of sensor is considered heavy-duty.

Unlike a standard pH sensor, which can become polluted as pH levels shift, using the third electrode acts as a barrier for the measuring electrode, guaranteeing an accurate estimation even if particles are present. As a result, these sensors should last longer and are suitable for demanding wastewater and industrial applications.

4.    Process pH Sensor

It employs combination sensor technology in bigger, more robust bodies. These sensors are also equipped with a process connection, making them ideal for constant monitoring of your water’s pH levels. Because of their more outstanding durability, these sensors can be installed in a tank or instantly positioned into a piping system. If either you need the sensor to observe industrial source water, process water, or wastewater. There are three types of process sensors: modest sensors, moderate to heavy-duty sensors, and heavy-duty/coating sensors with a flat bulb glass, which several people recognise as a self-cleaning style.

The Significance Of High-Quality Water

The quality of the water being used in numerous industries development is essential for the performance of goods and services provided, which implies that poor water quality can directly impact your ROI. Handling your water quality through various systems is also essential for adhering to strict environmental, industry, and safety regulations.

When it comes to water pre-treatment for production, this form of water quality control involves removing contaminants from intake water before using it in a range of distinct production processes. When these contaminants are eliminated, service efficiency increases, heating and cooling effectiveness improve, and you can more successfully maintain compliance with required water quality criteria. The advantages of having an excellent monitoring system in place can be multiple, which may include:

  • Conserving energy
  • Water conservation
  • Avoiding downtime
  • Keeping your employees in a healthy environment
  • Limiting the use of dangerous chemicals

Poor water quality can cause health problems, rough garments, and dry, itchy skin for the average consumer. A durable pH sensor is essential in water quality and water purification. If the pH of a water system gets too high or too low, the water can be threatening.

Maintaining this water level and constantly monitoring pH levels might also help you save money. However, to obtain the best water quality, you must use different pH sensors. The use of the third electrode in differential sensors, for example, tends to make this sensor ideal for a wide range of industrial applications such as wet scrubbers.

Conclusion

Recognising the differences between various kinds of pH sensors can be beneficial to your business. When it comes to constantly monitoring pH levels in a water reservoir or tubing, an industrial sensor outperforms a lighter weight research centre detector. The above guide may also assist you in making the best decision, saving you time and money in the long run.
