Control Time Fast Mode: 10 seconds to stable flag for 10% FS step
pressure change into a 50cc volume. Larger volumes
can lengthen this time. Controlling to low absolute
pressures will lengthen this time.
Slow Mode: 15 seconds to stable flag for 10% FS step
pressure change into a 50cc volume. Larger volumes
can lengthen this time. Controlling to pressures less
than 0.5 psia will lengthen this time.
Supply Consumption Fast Mode: Zero after setpoint is reached. All supply
gas is used for upscale pressure sample filling.
Slow Mode: Zero
Measure to Control Offset Fast and Slow mode: <0.0005% Span
Overshoot <1% of active range.
4.3 Control Specifications for the Solenoid Valve Regulator Module
External Pressure Requirements:
Source Requirements 10% over range of highest pressure transducer or 20
psi over highest pressure transducer for a pressure
channel, whichever is less.
Exhaust Requirements A vacuum source is required for sub-atmospheric
pressure control.
Stability of Controlled Pressure 0.003% of span on active range. Typically better than
0.001% of span 10 seconds after displaying stable
flag.
Sensor Spans Available in each Regulator
Type LP SVR: 0-1 psig to 0-50 psig (0-5 psia to 0-50 psia).
MP SVR: 0-10 psi to 0-150 psi.
HP SVR: 0-75 psi to 0-1500 psi.
Minimum Control Pressure 0.05% FS or .025 psi over exhaust pressure, which-
ever is greater.
Control Time 10 seconds to stable flag for 10% pressure step
change into 50cc volume. Larger volumes can
lengthen this time. Controlling to pressures less than
0.5 psia can also lengthen this time.
Pressure Control Rates Slow, Medium, Fast, Max (default).
Supply Consumption <2.5 scfh in steady-state control.
Overshoot Low overshoot mode: <.005%
High speed mode: <1%
