1. Minimum or maximum span, or any span in between, may be positioned anywhere within the operating range. For example, if a 0 to 30 psig (0 to 2 bar) sensing element is used
and the minimum span of 15 psig (1 bar) is set, the process indication can be calibrated to a range of –30 inch Hg to 0 psig (–1 to 0 bar), 0 to 15 psig (0 to 1 bar), 15 to 30 psig (1 to 2
bar), 27 to 42 psig (2 to 3 bar) or any value between the operating range minimum and maxi mum values.
2. Travel stops should be used when the maximum or minimum process pressure will be 5% over or under the calibrated range. For example, a 0 to 30 psig (0 to 2 bar) sensing
element is calibrated for 10 to 30 psig (0.7 to 2 bar), the desired range. The minimum expected pressure is 0 psig and the maximum expected pressure is 40 psig (2.8 bar). Travel
stops must be used to prevent excessive overtravel and undertravel since the maximum allowable overpressure and underpressure is higher than 5% of the 20 psig (1.4 bar) span
which is ±1 psig (70 mbar).
3. Bourdon tube without travel stops may be pressured to this value without permanent zero shift.
4. Bourdon tube with travel stops set may be pressured to this value without permanent zero shift.
