How to Specify Pressure Sensors for Hydraulic Applications

Hydraulic applications rely on fluid power or the use of pressurized fluids to generate, control and transmit power. These types of systems can produce high power and high forces in small volumes and have long service lives. Fluid power is used in a wide range of industrial applications including self-propelled scissor lifts, injection molding, machine tools, steel making and metal extraction, paper industries, textile machinery, disability lifts and security and parking barriers.
 
Pressure sensors are critical components in these systems, where they are used in a control loop with a Program Logic Controller (PLC) to help control the fluid pumps and ensure the system pressure is within a specified range. If a pressure sensor was to fail in these types of applications, the feedback to the control of a motor would be interrupted. This could lead to equipment failure, costly downtime or potential safety issues for workers using the equipment.
 
Pressure sensors play critical roles in hydraulic applications which typically involve high system pressures of greater than 50 bar (725 psi). These essential components help keep equipment running safely and efficiently - a failure due to incorrect specifications in the design process could lead to dangerous working conditions or costly downtime. Design engineers should carefully consider the frequent challenges encountered in hydraulic applications and key specifications such as sensing technology, burst strength, shock and vibration, and Electromagnetic Compatibility when selecting pressure sensors for these types of systems. Selecting components with more stringent ratings can help prevent component failure and increase the safety and reliability of the equipment.
