Pressure measurement is a crucial aspect of various manufacturing and technical processes. It is essential to monitor pressure levels to ensure that the process is running smoothly and avoid any industrial tragedies, making pressure transmitters a must-have device. Differential pressure transmitters are used to measure pressure differences between two points in a system, providing valuable insight into the process state.
Low pressure differential transmitters are used to measure non-aggressive gases and compressed air using a piezoresistive silicon sensor housed in a robust aluminum casing. These transmitters are compact, making them suitable for filter controlling, air conditioning technology, machine and plant engineering, and other similar applications. The differential pressure range of these transmitters is from 0.6mbar to 1000 mbar.
Industrial differential pressure transmitters can measure pressure in the range of 0.04 bar through to 16 bar, using either silicon or stainless steel piezoresistive sensors. These transmitters have an accuracy level of <0.25% and offer an output of 4-20mA or 0-10V. They are commonly used in industrial applications such as process engineering, where they provide invaluable feedback on the state of liquids, vapors, and gases.
A smart differential pressure transmitter is an enhanced version that uses a capacitive sensor to measure static overpressure up to 320 bar accurately. These transmitters are suitable for use in the chemical industry and other harsh environments where overpressure can be an issue. The accuracy level of these transmitters is 0.1%, and they can be manufactured with media wetted parts made of stainless steel, hastelloy, or tantalum.
In conclusion, pressure measurement is essential for various industrial applications, and differential pressure transmitters provide accurate and reliable readings. Low pressure differential transmitters are suitable for non-aggressive gases and compressed air, while industrial differential transmitters are built for harsh industrial environments. Smart differential pressure transmitters take pressure measurement to the next level by using capacitive sensors to measure static overpressure accurately. Choosing the right pressure transmitter for the application is crucial to ensure that the process runs smoothly and safely.
