PS-DR™
Dual Range Option |
Fuel
Cell Testing For Wide Dynamic Range
Beat the Resolution Limit Of Mass Flow Control!
Four Independent Gas Lines
Paired for Wider Range
Mass Flow Controllers (MFC) have a 1 part in 100 accuracy.
To provide a high accuracy over a wide dynamic range (particularly
in low flow ranges) the MFCs can be paired to provide
a high and low flow range with much better precision.
When coupled with the Power Station™, the PS-DR™
gas management unit enables fuel cell and the testing
of wide ranging reactant gas mixtures for PEM, alkaline,
and phosphoric acid fuel cells. It provides capacity
for small single cells and to fuel cell stacks.
Key Features
- Software control supports enhanced gas flow control
by “teaming” large and small mass flow
controller “pairs”
- Precision automated gas supply, product water collection
and effluent management
- Convenient front panel access to manual controls,
and output and return gas fittings
- Safety designed in through hardware features and
software control
