M2 pressure sensors are available to measure gauge (GI), compound (CI), differential (DI/DN), absolute (AI) or vacuum pressure. The display can read out in any of eleven pressure units or can be linearly scaled for special user units. Differential models offer a square root flow function to display flow rate in user defined units.
An adjustable damping feature minimizes the effects of pulsating pressures. A Min/Max function captures the extremes of pulsating or varying pressure signals and a Hold function can freeze the display at any point of interest. Auto Record documents up to 240 readings for future recall. -5º C

Certifications
Ex ia IIC T4 Class I,Div.1 Groups A,B,C,D, T4
Engineering Units
Inches of H 2 O (select 4 o C, 20 o C), PSI, mm of Hg, inches of Hg, Mbar, bar, kPa, kg/cm 2 , cm of H 2 O and user selectable scaling.
Media Compatibility
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.
Pressure Limits
Twice range on Gauge and Absolute units. Twice range on Differential units when pressurized on high side only and 10bar (10.5 Kg/cm 2 ) static when applied to both sides of the sensor simultaneously.
Leak Test
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.
Auto Record
Document up to 240 readings (automatically or manually) to reduce paperwork and field time. Saved readings can be recalled at any time.
Damping Rates
Exponential damping with user selectable time constant from 0.1 to 25 seconds.
Min/Max Capture
Capture speed is equal to the selected damping rate.
Field Re-cal
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
Auto Shut-Off
User selectable shut-off. Programmable at 10, 20, 30, 45, 60 minutes.
