DN: Non-isolated differential sensor for clean, dry, non-corrosive gases. GI & AI: Isolated Gauge or Absolute sensor for fluids compatible with 316L SS. See Meriam's M200-DI for wet/wet DP requirements.
Exponential damping with user selectable time constant from 0.1 to 25 seconds.
Accuracy: + 0.01% FS (+ 0.02% F.S. for DN0028) No temperature effect from 59o to 86o F (15o to 30o C).
Engineering Units: Inches of H2O (select 4 C, 20 C, or 60 F), PSI, mm of Hg, inches of Hg, mBars, Bars, kPa, kg/cm2, cm of H2O and user selectable scaling.
Pressure Limits: Twice range on Gauge and Absolute (GI and AI) units. Twice range on Differential (DN) units when pressurized on high side only and 150 PSI (10.5 kg/cm2) static when applied to both sides of the sensor simultaneously.
Allows users to view Min/Max pressure values and calculates leak rate per minute in pressure units. The feature is very handy when troubleshooting or pressure testing pneumatic systems.
Capture speed is equal to the selected damping rate
Document up to 240 readings (automatically or manually) to reduce paperwork and field time. Saved readings can be recalled at any time
The M2 series can be recalibrated in the field for zero, span, and linearity. The user has the option to select a 1 point or 5 point calibration procedure. Enables users with accurate primary standards to calibrate their devices locally if desired.
User selectable shut-off. Programmable for Disable, 10, 20, 30, 45, 60 minutes.
