Sometimes in industrial control, a simple contact closure is your best solution.
Process control instrumentation measures, controls, and monitors various chemical, pharmaceutical, and manufacturing processes. The accurate and reliable measurement of pressure and temperature is crucial for maintaining the quality of products and ensuring the safety of workers and equipment. Electromechanical pressure and temperature switches are process control instrumentation's most commonly used sensors. Despite the emergence of new sensor technologies, there will always be a need for electromechanical pressure and temperature switches in process control instrumentation.
Electromechanical pressure and temperature switches have several advantages over other types of sensors. One of the most significant advantages is their simplicity. These switches are relatively simple and have few moving parts, which makes them more reliable and less prone to failure. This simplicity also makes them easy to maintain and repair, saving time and money in the long run.
Another advantage of electromechanical pressure and temperature switches is their durability. These switches withstand harsh environments, such as high temperatures, corrosive chemicals, and high pressure, making them suitable for various industries and applications.
Electromechanical pressure and temperature switches are also cost-effective compared to other types of sensors. They are relatively inexpensive to manufacture and purchase at a lower cost than different types of sensors, making them an ideal choice for industries that require many sensors, such as refineries, paper mills, chemical plants, and water treatment facilities.
While many different types of sensors are available for process control instrumentation, each has advantages and limitations. For example, electronic pressure sensors are highly accurate and provide real-time data. Still, they can be expensive and prone to failure in environments with high electrical noise, shock, vibration, or extreme ambient temperatures.
Electromechanical pressure and temperature switches have several advantages over other sensors, including their simplicity, durability, and cost-effectiveness. While new sensor technologies are emerging, these switches will always be necessary for process control instrumentation. They are reliable, easy to maintain, and suitable for various industries and applications—electromechanical pressure and temperature switches are valuable components in process instrumentation.
