M4 Series SPECIFICATIONS
Pressure Measurement
M400: single pressure sensor (specified by customer)
M402: dual pressure sensors – any two compound gauge or absolute sensors, mix and match as desired
Accuracy: ±0.025% of Reading from 10 - 100% FS, ±0.002% of Full Scale under 10% of FS
Temperature Performance: Accuracy includes all affects of temperature from -20º to +50º C (-4º to +122º F)
Pressure Limits
DN sensors: 2x range when pressurized on P1 (HI) side only, 150 PSI
when applied simultaneously to P1 (HI) and P2 (LO) sides.
DI sensors: 3x range when pressurized on P1 (HI) side only,
3x range or 150 PSI (whichever is less) on P2 (LO) side only
1000 PSI when applied simultaneously to P1 (HI) and P2 (LO) sides.
CI, AI sensors: 2x range
Media Compatibility
DN sensors: Non-isolated for clean, dry, non-corrosive gases only (Brass, 316L SS, Silicon gel)
DI sensors: Isolated for fluids compatible with 316L SS and Viton
CI, AI sensors: Isolated for fluids compatible with 316L SS
