Description
Add temperature, voltage, current, pressure and other data inputs to the 840, 850 or 890 Series of Fuel Cell Test Systems: Our 892e multichannel data collection system for up to 16 additional channels of voltage and/or temperature measurement with SAI’s line of Turn-Key Fuel Cell Test Systems. The 892e is ideal for inlet/outlet pressure sensors, inlet/outlet cooling, or distributed stack temperatures, among others. Contact us for configuration information.
The Model 892e Data Expansion Subsystem is a hardware component intended to increase the input capabilities of the 850C/e and 890C/CL/e series of fuel cell test systems. The Model 892e is configured with two factory-installed eight-channel data acquisition modules, each of which is factory-configured for one of several input types.
