Measuring high range pressure is typically required when working with hydraulic systems that generate large loads and forces, such as cranes, lifts, construction equipment, and structural test machines.
On hydraulic systems the pressure is often in the order of a few hundred (x100) bars or a few thousand (x1000) psi. Hydraulic pressures can be highly destructive to sensitive components such as measurement instrumentation, and therefore these devices have a very robust mechanical design to withstand the rapid rise and fall of very high pressures over many cycles.
It is also possible to measure pneumatic systems with very high pressures. In some ways pneumatic systems are less destructive than hydraulic systems because there is no fluid movement to create a hammer effect, however the safety risks are a greater concern, because of the risk of escaping high pressure gas which is capable of propelling objects to a high velocity.
Pressure units which are used to describe high pressure ranges include bar (bar), megapascals (MPa) or pounds force per square inch (psi, lbf/in2), or kilopounds force per square inch (kpsi, ksi).
Pressure sensors are measurement devices for detecting variations in pressure of liquids or gases. Typically a pressure sensor is made of two subcomponents, an electromechanical assembly on the frontend, and a signal conditioning module on the backend.
The frontend of the pressure sensor is connected directly via a thread or clamped seal to a pipe or vessel containing the liquid or gas to be measured. The pressure generated by the liquid or gas will apply a force to a sensitive exposed surface area within the electromechanical assembly which produces a physical change to the material, such as a deformation. This physical change is translated into an electrical change by smaller elements incorporated into the sensitive part of the assembly, typically on the reverse side of the surface in contact with the liquid or gas.
Since there are many different types of electromechanical technology used to measure pressure, producing very different electrical characteristics, it is necessary to add on a signal conditioning module to rationalise the electrical signal and convert it to one which is a commonly used standard within a particular industry or application.
