Nowadays, pressure sensors are technologically advanced and designed to offer reliable performance than earlier ones. Most of these pressure transmitters are designed for long-term performance even in harsh environments of industrial, automotive, aerospace, gas turbine, oil processing, nuclear plant, and power station applications. Although they are built ruggedly using time-tested components, they are also prone to failure or sudden breakage at any time during their service life. However, being a critical instrument in every process monitoring and controlling applications, a sudden failure is not at all acceptable, as it leads to several hitches and consequences. However, by following a few tips, users can enhance the longevity/performance of pressure sensor to avoid unforeseen breakdown. This is what exactly covered in this post.

Performance and Service Life of Pressure Transmitter

Things to be noted to Augment the Performance of a Pressure Transmitter

Prevent unexpected failures and thus avoid costly replacement by abiding by the following tips.

Being one of the most fragile parts of the pressure transmitter, it is crucial to give additional care to the sensor diaphragm. Inspect the diaphragm on a regular basis, and ensure that it is in a good condition to withstand forces.
It is important to select these pressure-sensing devices after considering the application areas. To ensure the expected performance and longevity, the user must evaluate the following before the device is installed or monitoring purposes.
- Operational temperature ranges
- Chemicals and corrosive gasses compatibility
- Humidity or wet environment
Always act in par with the manufacturer’s instructions when wiring and grounding the pressure transmitter. This helps to prevent electromagnetic interference (EMI), which is a disturbance generated by an external source, that diminishes the performance of the sensor.
The price of the pressure sensors increases with the increase in the accuracy level. Hence, to get the expected performance, it is crucial to select the right model considering the level of accuracy required for the application.
It is important to fit the sensor in a pressure port it is designed for. Taking care of this is extremely important to augment the life and performance of your pressure transducer.
Ensure to provide added protection to sensor housing and cable if they are intended for applications near:
- Wash down area
- Electrically noisy area
Always opt pressure transmitters that are built confirming to specific approvals, or certifications. For example, pressure sensing devices meant for applications in petrochemical and oil and gas industries must be in compliance to hazardous location approvals.
Being a critical instrument for your process applications, you cannot afford buying a low quality pressure sensitive device that may give you inaccurate reading or may explode during the operation. To avoid such unforeseen situations and to get expected performance, it is important to procure the product from leading brands.

It would be too annoying to work with a pressure sensing device that fails to perform to the expected level, but gives troubles often. However, if you consider simple things as listed above right from the beginning, several performance problems can be avoided. When this fundamental knowledge is combined with the right selection of pressure transmitter from leading suppliers, working with pressure sensors will be easier than ever before!
