Notes:
1. Initial warm-up time for signal conditioned circuitry is 1 minute max.
2. Output Voltage is ratiometric to supply voltage.
3. Temperature shifts when sensing differential pressure correlates to the density change of the gas over temperature.
4. Output load connected from V
OUT
to GND (current sinking).
5. Maximum allowable rate of flow change to prevent damage: 5.0 SLPM/1.0 sec.
* A 5 micron filter must be used on differential pressure sensors.
MOUNTING DIMENSIONS (for reference only)
Note: Positive flow direction is defined as proceeding from
Port 1 (P1) to Port 2 (P2) and results in positive output. Do not
exert a force greater than 4.54kg (10 lbs.) in any direction.
