As technology develops, pressure transmitter is getting more innovative and more powerful. This means that the devices are getting more complex to use, which means they’re also getting more expensive. So now, it’s harder than ever to find an exemplary transmitter you can trust.
Pressure transmitters are an essential tool for any industrial production process. They help eliminate the need for costly investments in expensive equipment and provide a way to measure pressure without the need for expensive and difficult-to-use gauges. Many factors need to be considered, including the industry’s specific requirements and how the device will be used.
Many different pressure transmitters are available today, each with unique features and capabilities. However, selecting the suitable pressure transmitter requires knowledge of specific factors that experience can only teach. This post will help you learn about these factors and how they can affect your decision when selecting a pressure transmitter.
Some Critical Factors to Consider when Selecting a Pressure Transmitter
Wireless pressure transmitters are now widely used in critical operations, making them applicable to many industries. These devices help prevent expensive equipment failures by monitoring pressures in high-pressure fluid lines, pharmaceutical industries, and mining industries.
As a performance-centered device, the pressure transmitter must be chosen carefully. The factors that need to be considered when selecting a pressure transmitter are detailed as follows:
Pressure transmitters are used in a wide range of industrial processes. They can sense pressure and fluctuation in the process, making them so versatile. However, all possible pressure conditions must be addressed when selecting a pressure transmitter.
The pressure transmitter must be selected within a suitable operational pressure range. If not, the pressure will not be transmitted accurately and may lead to damage to the device or improper operation of your equipment.
Maximum and Minimum Pressures at Extremes
The device’s operating pressure must be monitored to ensure accurate results. The operator must know the highest and lowest pressure spikes during the operation. A low-pressure spike may hamper the device’s accuracy, whereas increased pressure may cause damage. The pressure transmitter selected must be able to handle both conditions. Otherwise, severe device damage might lead to accidents.
Interconnectivity of Processes
Pressure transmitters are often used in embedded systems. This means they are mounted on components like orifice plates, pressure tanks, pipeline inlets or outlets, etc.
Therefore, various mountings are available depending on the connection’s versatility. The selection of transmitters must complement the mounting or variety of connectivity. A few important ones are listed below:
- Inline Mounting
When pressure transmitters are connected directly into a single connection at the measuring end of the pipe, they are called in-line pressure transmitters. The transmitters can be used in operations that require direct pressure measurement.
Inline Pressure Transmitters are used in various industries to measure the level, temperature, pressure, and flow rate of fluids and gases. They are used in pharmaceuticals, food & beverages, oil & gas, petrochemical, chemicals, and science research.
- Coplanar Mounting
This type of connection is intended for the detection of differential pressure. It is a coplanar pressure transmitter and can be selected for operations requiring absolute or differential pressure measurements.
A coplanar pressure transmitter has two process connections at the bottom. The coplanar pressure transmitter is placed on a single process flange. This makes it lightweight compared to other mounting styles.
- Bi-planar Mounting
The bi-planar pressure transmitters are connected to two ports in the measuring line in this biplane assembly.
In this configuration, two pressure transmitters are connected with two ports in the measurement line. Installing one pressure transmitter with the flow inlet side and one with the outlet side is recommended. The placement of the pressure sensors (inlet or outlet) depends on the pressure sensors and the measurement line. Placing the pressure sensors with the flow inlet side will result in forward sensing, and placing them with the flow outlet side will result in reverse sensing.
The pressure sensors may be exposed to oil, chemicals, temperature, corrosion, and other mechanical components. To avoid damage to the impulse lines, remote seals are one option. These remote seals help to isolate the sensing elements from damaging media, which may reduce accuracy or damage them. Furthermore, these seals provide for simple cleaning alternatives to enhance setup performance. Therefore, remote seals should be selected when choosing pressure transmitters.
When selecting one, it is vital to consider the environment where the pressure transmitter operates. The following are environmental or operational considerations that should be taken into account.
- When selecting a pressure transmitter, choose one with a remote seal that can withstand high temperatures, as temperature may rise beyond comprehension in specific applications, such as fluid pressure measurement.
- When choosing a transmitter, you should consider mechanical vibrations. A transmitter should be installed in a low-vibration, low-fluctuation environment.
- Sensors are susceptible to damage caused by pressure fluctuations. It is, therefore, necessary to consider the transmitter’s compatibility with the pulsation damper when choosing a transmitter.
- ATEX, CSA, FM, and IECEx approvals are needed if the transmitter is used in hazardous areas.
