Measurement Computing DBK Part 2 - Manual (Page 190)

Overview
Features
o
Measure vehicle engine temperatures with remote DBK100s
o
One cable transmits up to 56 channels of TC measurements from the engine
compartment to the data acquisition system
o
Up to 896 TCs per system
DBK100/D and DBK100/T provide thermocouple measurement capability for in-vehicle applications, and
are well suited for TC measurements in proximity to a vehicle engine. With operating temperatures in the
range of -40° to +125°C, DBK100 Series devices are ideally suited for applications where engine
compartment temperature measurements are required.
The DBK100/D is housed in a rugged and water resistant, all-metal package designed specifically for harsh
environments. TC and system connections to each DBK100/D are water resistant, and are accessible from
one direction, enabling the DBK100/D to be mounted and its I/O accessed without having to be removed.
Maximum system capacity is 896 thermocouples when two DBK101 modues are used; or 448
thermocouples when one DBK101 module is used, as indicated in the following figure. For clarity,
thermocouple lines are not shown.
DBK100 System Example
These capacities were derived as follows:
o
14 thermocouples can be connected to each DBK100/T or DBK100/D.
o
Up to four DBK100/T or DBK100/D units can be connected to a each DBK101 channel. This is
illustrated in the preceding figure.
o
DBK101 has 8 channels. Thus 32 DBK100 units can be connected to a DBK101. With 14
thermocouples possible per DBK100, 448 thermocouple connections are possible.
o
Two DBK101 hubs can be connected to a DaqBook/2000 Series unit. When 2 hubs are used the
system can have up to 896 thermocouples (448 x 2).
