*If the measured differential pressure is expected to go from positive to negative, a

transmitter with offset (elevated zero) should be ordered.

Three options are available:

“0”

No offset. At zero differential pressure, the output signal is:

4 mA (4 to 20 mA range)

Pressure excursion

0% to 100% of range, see standard pressure ranges tables on page 4

“A” 1/4 span offset. At zero differential pressure, the output signal is:

• 8mA(4to20mArange)

Pressure excursion

-33% to 100% of range see standard pressure ranges tables on page 4

“B” 1/2 span offset. At zero differential pressure, the output signal is:

• 12mA(4to20mArange)

Pressure excursion

-100% to 100% of range, see standard pressure ranges tables on page 4.

To order: Determine the positive pressure range. From standard pressure

ranges table on page 4, find the corresponding pressure code. Add the required

offset (none, A, or B).
