The Aneroid Bellows is a maintenance-free alternative to desiccant filters for moisture protection on vented gauge transducers. Made of flexible neoprene material attached to a polycarbonate mounting bracket, the bellows fluctuates with changes in atmospheric pressure maintaining a constant barometric reference. Note that the use of the bellows results in a closed reference pressure system subject to zero shift errors induced by changing temperatures of up to 0.003 psi/ºC. The bellows is not recommended for use with accuracy requirements of ±0.25% FS or better, nor for ranges < 2 psi.
