1. Span is adjustable between minimum shown and maximum of the capsular element operating range and can be positioned anywhere within this range. For example, if a 0 to 2.0 bar (0 to 30
psid) capsular element is used and the minimum span of 1.0 bar (15 psid), 1.0 to 2.0 bar (15 to 30 psid), or any value between minimum and maximum value of the operating range.
2. Maximum difference between the two input supply pressures.
3. Capsular element may be pressured to this value (after reaching travel stop at upper range limit) without permanent zero shift or structural damage to controller components.
