Flexial's Edge-Welded
Performance Advantage
New bellows design incorporating edge-welding technology replaces the old resistance weld design, resulting in 30% longer life and vastly improved linearity - a key failure mode of the original design where spring rate increases with bellows deflection (movement). Couple that with controlled and repeatable manufacturing processes and the result is linearity so consistent there may be no need to match range springs in calibration - and unit-to-unit calibration is virtually the same in every system.
Higher Performance – Greater Repeatability
Longer Life – Lower Cost

Differential Pressure Unit Bellows Assembly
This bellows assembly consists of two opposing internally connected bellows. Linear movement of the bellows which actuates a chart recorder is caused by a change in pressure. Flexial offers a line of Stainless Steel and Alloy 625 bellows assemblies for this line of Differential Pressure Units.
