A barometer of the type having a stabilized membrane capsule includes a transmission mechanism for transmitting the motion of the membrane capsule to a pointer mechanism. The transmission comprises a lever shaft with two lever arms thereon, one coupled to the pivotable drive element of the pointer mechanism and the other having a free end abutting directly on the membrane capsule and having an axis which extends obliquely relative to the plane of the membrane capsule.

A barometer comprising a substantially planer stabilized membrane capsule, a base plate supporting the membrane capsule on one side thereof, pointer drive means disposed on the other side of the membrane capsule and including two substantially parallel plates fixed with respect to the base plates, a pointer shaft rotatably mounted in the two plates and a pivotably mounted drive element engaged with the pointer shaft to rotate same in response to the pivoting movement thereof and transmission means for coupling the membrane capsule to the pointer drive means, the transmission means comprising a rotatable lever shaft, a first lever arm mounted on the lever shaft for rotation therewith and coupled to the drive element to pivot same in response to rotation of the lever shaft and an elongated second lever arm mounted on the lever shaft for rotation therewith and having a free end abutting directly on the membrane capsule to effect rotation of the lever shaft in response to movement of the membrane capsule and wherein the longitudinal axis of the second lever arm extends obliquely relative to the plane of the membrane capsule.
