How to Choose Pressure Transmitters for Your Industry

by Alex Hales

Pressure transmitters are a practical, precise, and dependable method of monitoring pressure in various industrial applications, including process tanks for calculating fluid level, pipelines, producing fresh water, flow rate, and oxygen generators. Because there are so many alternatives and models to choose from, it might not be easy to find one ideal for all your prospective uses and placements. For a well-informed decision, there are a few factors to remember when choosing pressure transmitters for your industry, as explained.

Pressure Transmitters

Pressure transmitters are devices that detect pressure and transmit an output signal proportional to the measured pressure change. Piezoresistive pressure transmitters from MicroSensor take low electrical output signals and turn them into higher-level signals that are sent and processed over a long distance by a built-in pressure signal and provide accurate readings over a lengthy period.

How to Choose Pressure Transmitters for Your Industry

Consider operating environment

The case and wetted materials of the transmitter can be tailored to its intended environment, increasing its life span. The evaluated medium should play a role in the choice of each transmitter. Check that the medium’s specific properties are compatible with the transmitter because some transmitters may not function reliably in high temperatures or vibration as they may lead to an inaccurate output.

Accuracy requirements

Pressure transmitters contain different accuracies depending on your performance requirements; hence you can use accuracy to choose the kind of transmitter and its properties. Precise readings are essential in critical operation applications or when dealing with very low pressure. Therefore, high-accuracy transmitters are more suitable.

Should contain remote seals

In many industrial applications, pressure sensors are mounted into other mechanical parts and can be subject to chemicals, oil, corrosion, extreme temperatures, and other forms of deterioration.

Accordingly, remote seals are one option if pressure sensors are to be built into impact lines, as they provide a shield to the different parts from potentially destructive media, protecting the transmitters from degradation and maintaining their accuracy, which may provide simple cleaning alternatives that boost the system’s efficiency. Therefore, it is important to choose pressure transmitters that have remote seals.

Application

You can measure pressure in various ways, but the most common are absolute, sealed gauge, and differential pressure transmitter. The kind of measurement required depends on the application.

Process connection

Pressure transmitters are common in large industrial systems. You can install them on various parts, such as pipelines, orifice plates, outputs, and pressure tanks. Consequently, there are numerous mounting options based on the adjustability of the connection. It would help if you chose transmitters that work well with the chosen mounting or connecting method.

Take away

If you observe the mentioned considerations while selecting a pressure transmitter, you should be able to get your desired efficiency. Avoid a transmitter model that could interfere with the system’s function or raise the chance of an inaccurate reading. You may get a good idea of the options by checking out the many models available to determine what works best for your needs.
