FIELD: measuring equipment engineering.
SUBSTANCE: device has two profiled stripes hermetically connected at edges and forming external and internal contours of manometer spring cross-section. Materials used to make these profiled stripes have various mechanical characteristics and have different moduli of elongation. According to another variant, profiled stripes forming external and internal contours of spring cross-section have different wall thickness.
EFFECT: higher precision, higher durability.
