Pressure Limits
Working Pressure Range .................... -97.90 kPa (-14.2 psi) gauge to 20 MPa (3000 psi) gauge
Supply Port ........................................ 23 MPa (3300 psi) gauge
Test Port ............................................ 20 MPa (3000 psi) absolute
Reference Port ................................... 115 kPa (17 psi) absolute
Vent Port ............................................ 150 kPa (22 psi) absolute
Relief Valves
Chassis Supply port relief valve is set to 24.1 MPa (-0/+700 kPa), 3500 psi (-0/+100 psi)
Exhaust port relief valve is set to ~830 kPa (120 psi).
Each Pressure Measurement Module (PMM) includes a module-specific pressure protection device.
Supply Gas Type
Clean Dry Air or Nitrogen (Industrial Grade, 99.5 %)
Maximum Particulate Contamination ≤ 1.25 micrometer (50 microinches)
Maximum Moisture Content ................ -50 °C dew point
Maximum Hydrocarbon Content ......... 30 ppm
Vacuum Supply
>50 liters per minute capacity with Auto Vent feature
Exhaust gas will pass through the vacuum supply. Appropriate protections should be taken when operating at higher
pressures.
Interface / Communications
Primary remote Interfaces .................. Ethernet, RS232, USB
Electrical Measurement Module (EMM)
Connection .......................................... Banana Jack
Maximum 30 V dc w.r.t. chassis ground
Aux Drivers ......................................... 4 external Solenoid Drivers
24 V dc. 100 % duty cycle when turned, reducing to 40 % shortly after.
Pressure Control Specifications
Control Precision (Dynamic Mode)
PM200-BG2.5K ............................... 0.005% Range Span
All other Ranges ............................. 0.001 % Range Span
Control Turndown ........................... 10:1 (Typical)
Control turndown is defined as the relationship between the provided supply pressure and the appropriate supply
pressure for the range. For example, a unit with a 7 MPa (1000 psi) and 700 kPa range (100 psi) with a supply
pressure of 7.7 MPa (1100 psi) provides control precision of 0.001 % range because 7 MPa is 10 times greater than
700 kPa. A system with ranges of 20 MPa (3000 psi) and 700 kPa (100 psi) with supply pressure of 22 MPa (3300 psi)
will have 0.001 % range control precision on the 20 MPa range but only 0.003 % control precision on the 700 kPa
range. Control precision of 0.001 % on the low range can be achieved by reducing the supply pressure.
Low Control Point ............................... 1 kPa (0.15 psi) absolute
Time to Setpoint (Typical)
PM200-BG2.5K ............................... 40 seconds
All other Ranges ............................. 20 seconds
Typical set time is the time required to be within 0.005 % of the setpoint for 10 % steps into volumes of 0 to 50 cm
3
and
pressures above 50 kPa (7.25 psi) absolute. Lower absolute pressures requires longer set times depending upon
quality of the vacuum pump, diameter and material of tubing used, and test volume.
Maximum Overshoot ........................... 0.02 % Range Span
