Overview
GRANITE TEMP 120 20 channel thermocouple module is a module specifically designed for thermocouple measurement. Using a universal thermocouple socket, there are 20 universal thermocouple input channels. TEMP120 is used to handle harsh temperature environments and rapid thermal gradients applied to measurement modules. Each input terminal has a separate cold end reference temperature, which has been carefully designed to reduce temperature measurement errors in the presence of external temperature gradients.

6. Provide USB 2.0 interface for PC connection
detailed description
GRANITE TEMP120 20 Channel Thermocouple ModuleThe input is a universal copper/copper interface that allows for the connection of any type of standard thermocouple.GRANITE TEMP120 20 Channel Thermocouple ModuleIt is a part of the data acquisition system, which includes a DAQ (such as GRANITE 6, 9 or 10, CR6 or CR1000X data collector). The clock synchronization timing between modules is managed by the data acquisition system or data collector through the CPI communication port. The clock reference can refer to GPS or temperature compensated real-time clock. The measurement module can be centralized or distributed through network cables to make it closer to the measurement point. Therefore, in applications that require hundreds of thermocouples for measurement, it is easy to form a unified data acquisition system.
