Description
The model 614.11 and 634.11 capsule pressure gauges are based upon the proven capsule measuring system. The capsule measuring principle is particularly suitable for low pressures. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated.
The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges. Due to this high variance, regarding design and back mount connection, the instrument is suitable for panel mounting in a wide range of applications.
