High-range pressure measurement is critical in various industries and applications. Mobile hydraulics, used extensively in construction vehicles, earth movers, elevators, and lifting equipment, rely heavily on accurate high-pressure readings for safe and efficient operation. These systems often operate at pressures exceeding several thousand psi, requiring robust instrumentation capable of withstanding harsh environmental conditions and frequent pressure fluctuations. High-pressure measurement is also crucial in the testing equipment used to develop, manufacture, and maintain these mobile hydraulic systems, ensuring performance and reliability. Furthermore, these instruments are indispensable in industries like manufacturing, where they are used in processes like injection molding and the operation of heavy machinery. They are also essential in the oil exploration industry, where they are used to monitor and control high-pressure operations in drilling and production.
Hydraulic systems that generate large loads and forces, such as those found in cranes, lifts, construction equipment, and structural test machines, often require high-range pressure measurement. These systems can operate at pressures of hundreds or even thousands of bars (or tens of thousands of psi). The destructive potential of such high hydraulic pressures necessitates the use of robust instrumentation. High-range pressure sensors and gauges are specifically designed to withstand the rapid rise and fall of these extreme pressures over numerous cycles, ensuring long-term reliability and accuracy. These instruments often incorporate specialized materials and construction techniques to prevent damage from pressure spikes, fluid hammer, and other harsh conditions.

While hydraulic systems pose a significant challenge due to the incompressible nature of liquids, pneumatic systems operating at very high pressures also require careful consideration. Although pneumatic systems may not exhibit the same fluid hammer effect as hydraulic systems, the risk of escaping high-pressure gas poses a serious safety concern. The potential for propelled objects and rapid decompression events necessitates the use of specialized pressure measurement equipment and stringent safety protocols.
Common units for expressing high-pressure ranges include bar, megapascals (MPa), pounds force per square inch (psi), and kilopounds force per square inch (kpsi). Understanding these units and their conversions is essential for selecting the appropriate instrumentation for a given application. For example, in the oil and gas industry, pressures are often measured in thousands of psi (kpsi), while in other industrial applications, bar or MPa might be more common. The choice of pressure unit often depends on industry standards, regional practices, and the specific requirements of the application.

Avoiding failures due to dynamic hydraulic pressures
Hydraulic high pressure measurement applications can be extremely unforgiving to some pressure transducers especially in highly dynamic systems which are testing hydraulic actuators or valves.
In some hydraulic systems it maybe appropriate to combine all of the methods below to protect a pressure measurement device, but it is also worth carefully choosing the pressure sensing technology that is most suited to the punishing changes in pressure it will be subjected.
Pressure surges
The constant opening and closing of hydraulic valves can create large surges in pressure sending shockwaves through the system. If the most appropriate pressure sensing technology is not employed this can lead to irreparable damage to the sensing element.
Blocked snubbers
One method to protect a high pressure transducer in a hydraulic system is to fit a snubber or a restriction inside the pressure connection. A snubber is very effective in absorbing high frequency shock pressures, but there is a trade off with the dynamic response and over time the snubber or restriction could become blocked from a build up of contaminant particles.
Compromising precision for overpressure
Another method to reduce the effect of hydraulic pressure spikes is to use a much higher range pressure transducer than you need so that its over-pressure rating is effectively increased. But this again leads to compromise in measurement performance which in this case is a combination of accuracy, signal to noise and lower output signal.
