Pressure indicators encompass instruments and sensing assemblies that measure and display fluid and gas pressures across aircraft systems, including oil, hydraulic, bleed air, and cabin differential pressure, utilising technologies such as Bourdon tube mechanisms, piezoelectric transducers, MEMS-based sensing elements, and ARINC 429-compatible digital signal conditioning to convert pressure data into cockpit-readable outputs.
