Pressure gauges are among the most common pressure measurement devices worldwide. The principle of the “Bourdon tube”, developed by Eugène Bourdon in 1849, has a predominant role in the development of this technology.

Bourdon offers mechanical pressure gauges for accurate measuring of relative, absolute and differential pressure covering measuring ranges from 0…6 mbar to 0…1600 bar and compatible with almost every application.

Mechanical pressure gauges are local indicators without external power supply. The indication is generated by the elastic deformation of a mechanical sensing element when pressurized. Different types of sensing elements allow solutions for nearly every kind of application. Many options can be selected to adapt the pressure gauge to specific process or application requirements e.g. medium compatibility, overpressure protection, safety, specific dials etc. Proven technologies, many years of experience, modern production methods and a certified quality management system guarantee excellent measurement results even under extreme operating conditions.
