Fits low differential and low-pressure control where you need an Additel ADT 773. Controller covering ADT773-LLP about −380 to 400 inH2O (−0.95 to 1 bar) and ADT773-D about −380 to 2,800 inH2O (−0.95 to 7 bar), with selectable accuracy 0.01% FS or 0.02% FS module-dependent.
Key advantages
- LLP — To ~1 bar / 400 inH2O
- D model — To ~7 bar / 2800 inH2O
- Accuracy — 0.01% or 0.02% FS
- Use — Low DP / low pressure control
- Modules — Module-dependent specials
Typical applications
- Low DP calibration.
- HVAC / cleanroom pressure.
- Lab low-pressure control.
