The model 611.13 capsule pressure gauges are based upon a modular capsule measuring system. One half of the capsule element forms the plastic case and the other half is made of copper beryllium.

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 customer-specific applications. The model 611.13 capsule pressure gauge is used with great success, particularly in medical applications.
