Solution

Split Range And High Flow Control

Two requirements turn up together often enough to be treated as one problem: a single control signal that has to drive two final elements across different parts of its range, and an actuator that needs more air than a standard transducer will pass.

The process

Step By Step

STEP 01Decide where the split falls
STEP 02Set each unit separately
STEP 03Size the flow for the larger element
  1. Decide where the split fallsThe T1000 3-15 psig model recalibrates to 3-9 psig or 9-15 psig for split ranging. The PT700 offers a split range start at 4 mA or 12 mA.
  2. Set each unit separatelyCalibrate each transducer to its half of the range so the two do not overlap or leave a gap in the middle.
  3. Size the flow for the larger element12 SCFM on a standard T1000, 24 SCFM on the extended range build, 9.0 SCFM on a zero based T1500.
  4. Check the supply windowExtended range T1000 units take supply to 150 psig (10.4 BAR); zero based T1500 units need between 25 and 150 psig depending on output range.
  5. Add exhaust capacity if the element has to release fastThe T1000 high relief build exhausts 7 SCFM (336 SLPM) against 2 SCFM on the general purpose build.
  6. Verify both elements togetherStroke the signal from bottom to top and confirm the handover point behaves as the control strategy expects.

FAQ

Questions About This Process

Which models support split range

Split range operation is a listed feature of the T7800 series. The T1000 4-20 mA, 3-15 psig model can be recalibrated to 3-9 or 9-15 psig, and the PT700 offers a split range start at 4 mA or 12 mA.

What is the highest flow available

24 SCFM (677 SLPM) from the T1000 extended range build at midrange on a 150 psig (10.4 BAR) supply.

How do I get faster exhaust

Order the T1000 high relief build. It exhausts 7 SCFM (336 SLPM) at 5 psig above setpoint, suitable for cylinder return strokes and air hoists.
