Pressure

Pressure measurement covers instrumentation for process (absolute and gauge) pressure and differential pressure, and it is frequently extended into hydrostatic level and differential-pressure flow applications. Endress+Hauser groups the category around absolute/gauge pressure measurement, hydrostatic level measurement, and differential-pressure flow measurement—reflecting how pressure sensing supports multiple core measurement tasks in process automation.

Pressure is a primary indicator of process state, equipment loading, and safety margin. Stable pressure measurement supports control of pumps and compressors, reactor and vessel operation, and leak or blockage detection. Differential pressure is widely used for filter monitoring, flow measurement across primary elements, and validation of operating conditions across heat exchangers and other process equipment where fouling or restriction changes performance over time.

Engineering the measuring point requires attention to range selection, overpressure protection, wetted-material compatibility, temperature effects, and installation geometry. Absolute and gauge transmitters are selected based on reference needs and expected vacuum/overpressure conditions. Differential pressure installations depend on impulse-line design (or alternative approaches) to manage condensation, plugging, and response time. Hydrostatic level measurement adds considerations for density variation, mounting elevation, and the choice between direct immersion or diaphragm-seal configurations depending on process media and hygiene requirements.

Typical applications include discharge and suction monitoring on rotating equipment, pressure control in reactors and columns, steam and condensate systems, and header monitoring in utilities. Differential pressure is applied to track filter condition, to measure flow where appropriate primary elements are used, and to support verification of equipment health. Hydrostatic pressure measurement supports tank and vessel level duties where head pressure provides a direct, robust proxy for inventory.

Pressure measurement performance is sustained through disciplined calibration, proof testing where required, and consistent integration into the control and maintenance ecosystem. Modern transmitters are commonly deployed with standardized outputs and digital communication options to support diagnostics, configuration management, and lifecycle documentation. The category is positioned to provide measurement solutions for a wide range of applications and industries by enabling selection of an appropriate pressure measuring point for the process.
