Pressure gauges and switches are among the most often used instruments in a plant. But because of their great numbers, attention to maintenance–and reliability–can be compromised. As a consequence, it is not uncommon in older plants to see many gauges and switches out of service. This is unfortunate because, if a plant is operated with a failed pressure switch, the safety of the plant may be compromised. Conversely, if a plant can operate safely while a gauge is defective, it shows that the gauge was not needed in the first place. Therefore, one goal of good process instrumentation design is to install fewer but more useful and more reliable pressure gauges and switches.

- It cost is low.
- Time tested application.
- Accuracy is high
Application
Pressure transmitters are used in a wide variety of applications. They are used in machinery to warn machine operators of high pressure levels before a disaster takes place. Pressure transmitters also ensure that machines do not apply too much or too little pressure during production. Pressure transmitters can be used in conjunction with other devices to measure depth, altitude, water flow, and even pressure loss in order to prevent leaks in a system.
