MPS4264TCU
Thermal Control UnitFeatures• Maintains a stable temperature environment for
MPS4264 series pressure scanners• For use with MPS4264/64CPx and 		MPS4264/64NPx models• Quick disconnects for electrical and pneumatic I/O• Rugged IP-54 rated aluminum case

General Description
The MPS (Miniature Pressure Scanner) line ofThermal Control Units is designed to provide acontrolled temperature environment for MPS4264
series electronic pressure scanners. The MPS4264
pressure scanners incorporate temperature compensated piezoresistive pressure sensors whichmust remain in a controlled temperature environment to provide the most accurate pressure measurement. All MPS4264TCU's include a rugged
anodized aluminum enclosure, pneumatic connectors, mating pnuematic connector, a single electrical/data connector, and breakout cable with flyingleads.
The MPS4264TCU offers an optional heater circuit
for use in environments as cold as -60°C. This
heater circuit utilizes two 20 watt heaters to keep
the MPS4264 scanner within its temperature compensated range (0-70°C). Exceeding the compensated temperature range can induce errors in thepressure measurements.

Application
Thermal Control Units are most commonly utilized
in flight test, automotive, wind turbine, wind tunnel,and engine test applications where temperatures
tend to vary and are often extreme.
Thermal Control Units may also be used anywhere astable temperature environment is not available for
MPS pressure scanners. Although the environmental
temperatures are within the compensated range ofthe scanner, a Thermal Control Unit can be used toimprove measurement accuracy and limit any effects
from temperature.
Thermal Control Units also provide a ruggedized
enclosure to protect the scanner's components frommoisture, dust, debris, and other contaminants that
could harm the scanner.

For higher temperature applications (60-125°C)
the Cooling Kit variant of the MPS4264TCU isrequired. The cooling kit variant contains the sameheater circuit as the heater only MPS4264TCUvariant. With the addition of the cooling kit, the MPS4264TCU can keep the MPS in the compensatedrange while the environmental temperatures range
from -60°C to 125°C. Approximately 3.0 CFM of23°C cooling air is required to properly cool theMPS while subject to the 125°C environment.
The electrical connector is a 17 contact M12 seriesconnector which provides module power, heaterpower, scan triggering, and Ethernet data. The
pneumatic connector is a Scanivalve 70MPS seriesconnector. These features make for easy use andadaptability when implementing the MPS4264TCU
into a complex system.
