eDAQ Non-Isolated Thermocouple Layer

Overview

The SoMat eDAQ Non-Isolated Thermocouple Layer (ENTB) measures temperatures on 32-channels of non-isolated thermocouple signal conditioning. Thermocouples come in several styles of dissimilar metals, or calibrations; and the ELNTB is compatible with the four most common calibration types (J, K, T and E). Each channel is individually software-selectable between these calibrations.

Since 16-channels (x2) share a common cold junction, the ENTB has excellent channel-to-channel accuracy. This is particularly valuable when measuring things such as thermal gradients.

In addition to the ENTB layer, (2) SoMat Cold Junction Thermocouple Boxes (ECJTB) are required for the thermocouple termination.
