7 aneroid capsules
It uses a set of 7 aneroid capsules with a diameter of 62 mm made fromcopper-beryllium alloy. This material essentially eliminates age-hardening, hysteresis, and elastic after effects that could otherwise degrade the accuracy.
The influence of temperature on the set of aneroid capsules and the transmission system is compensated by use ofbi metalcomponents over the full measuring range and for temperatures between -30 to +40 °C (-22 to 104 °F).
All contacts in the movements are jeweled to reduce friction.
