Industrial pressure sensors: Key components and future trends


Of the many industrial sensors used by manufacturers today, industrial pressure sensors are one of the most common and useful. They are a key component of real-time equipment condition and performance monitoring processes that enable predictive maintenance, one of the most effective ways to improve facility cost efficiency.



Pressure sensors work by measuring the difference in pressure in containers, conveyor equipment, or other hardware or infrastructure. Its main operating principle is a device that can expand or contract in response to applied pressure, whether liquid or gas.







As the pressure changes, the device expands or contracts and generates an electrical signal, which is then converted into an output for real-time readings, data analysis and other applications to facilitate more effective and efficient equipment maintenance and monitoring. Pressure sensors work alongside transducers and transmitters to create actionable information for technicians, managers and analysts.







The difference between pressure sensors, transducers and transmitters







Pressure sensors, pressure transducers, and pressure transmitters can all take pressure measurements and produce data and outputs, but they are not the same or interchangeable. Each device plays a unique role in acquiring and communicating data, recording and analysis.



Pressure sensors: Operate in a direct manner, generating electrical signals based on the action of the mechanical measuring device. The signal form of the pressure sensor is voltage.



Pressure transducers: Similar to pressure sensors, voltage output signals are generated based on the way pressure changes affect the mechanical device. Pressure transducers are able to transmit signals farther because they contain built-in signal conditioning capabilities.







Pressure transmitter: Unlike a voltage output, a pressure transmitter generates an electric current to generate its signal. The measurement method is the same, through the physical device's response to the pressure difference.







Type of pressure sensor



The seven main types of pressure sensors used in industry include:



Vacuum pressure sensor: Usually referred to as the Pirani sensor, which generates a signal based on the resistance change on the integrated sensor silk path.



Piezoelectric pressure sensors: Based on changes in the strength of the charge, this type of sensor produces a signal proportional to the pressure applied, with an almost immediate response time.







Barometer pressure sensor: Use mechanical operation to directly generate pressure readings based on the flexible capsule device.



Manometer pressure sensors: Use a liquid-filled U-shaped tube to provide direct pressure readings through fluid displacement.



Bourdon tube pressure sensor: Similar to a barometer sensor, but using its namesake device, a spiral or C-shaped tube that straightens as pressure is applied.



Sealed pressure sensors: Often used in unique atmospheric pressure situations, such as in submarines, these types of sensors contain a standardized atmospheric pressure that is used as a reference.



Strain gauge Pressure sensor: A spring is used to respond to pressure applications, and the change in spring form generates an electrical signal that is converted into a pressure readout.







Applications of industrial pressure sensors



Industrial pressure sensors have a wide range of applications in several fields, which further expand the range of potential uses. For example:



Monitor the process traffic on the device



Hydraulic and pneumatic systems



Vacuum technology



Monitor the tank level



Environmental application
