F. PRESSURE SENSOR BOARD
The pressure sensor option provides:
• Vacuum pressure sensor 0- (-15) psig
• Sample pressure sensor 0-30 psig
• Calibration gas pressure sensor 0-30 psig
Outputs
1. The standard output from all sensors is 4-20 mADC, isolated, loop powered1
2. Outputs are terminated on the Flow Control Drawer back panel on the analog
output Pressure Transducer Terminal Strip.
