Electrochemical transmitters are widely used in

Electrochemical transmitters are an integral part of our daily lives and account for the largest proportion of all chemical sensors. Electrochemical sensors are in use and/or are being developed for a wide range of applications. Some examples include gas sensors such as those used to detect CO in the home, heavy metal sensors used in water quality analysis, and hydrocarbon, alcohol and ketone sensors used to measure engine oil degradation.

Applications of electrochemical transmitters

Electrochemical transmitters are used in a variety of applications and continue to play an important role in many industries. Some of the most common applications include:

1.Air quality environment monitoring

Due to the expanding industrial world, many countries are affected by poor air quality, especially in urban areas. This poses a threat to the quality of life, and the main sources of air pollution are nitrogen oxides, sulfur oxides, hydrogen sulfide, and some volatile organic compounds. Electrochemical gas sensors are now becoming important tools for monitoring and controlling pollutants that affect air quality. They provide a cheaper alternative to widespread air monitoring and can replace traditional and more expensive air quality monitors based on infrared spectroscopy and gas chromatography.

2.Detection of explosive gas and toxic vapor

In hazardous locations in the manufacturing and chemical industries, there is an increasing focus on explosion protection. This is due to the presence of toxic and flammable gases. Monitoring of these hazardous areas contributes to a safer work environment. Government and industry regulations require workers to only be exposed to toxic gases and fumes. This suggests an increase in the use of electrochemical gas sensors, which can improve sensitivity and selectivity for a wide range of toxic gases.

3.Oxygen monitoring in the medical field

Electrochemical oxygen sensors are used in many makes and models of medical respirators and ventilators used in respiratory therapy, life support systems, and emergency medicine. When critically ill patients are at risk of not getting enough oxygen from ambient air due to respiratory problems, a ventilator is used to deliver an oxygen-enriched mixture of medical-grade O2 and ambient air through a pressurized tank. The percentage of oxygen required depends on the severity of the patient's illness, so measuring the concentration and flow of oxygen is critical to the patient's health. Their small size, ease of implementation, and simple operation make electrochemical transmitters ideal detection and monitoring devices in healthcare.

4.Food quality control

As the world's population grows, so does the need for improved food supply, transportation and storage. Controlling food quality is important to both suppliers and consumers. However, electrochemical sensors are commonly used to monitor industrial oxygen. Their use in food industry applications is increasing due to reliable measurement and fast response time, and they are widely used due to compact size and low cost. Carbon dioxide and ethanol are used in the food and beverage industry, so continuous monitoring of the gas is required to prevent people from ingesting toxic or harmful gases. Other applications requiring gas detection include steam processes, inert gases for packaging, CO2 for carbonation, toxic gases for sterilization, and ammonia for refrigeration.
