PXIe—4353
Product Description
32-channel, 24-bit PXI temperature input module. The PXIe 4353 thermocouple input module provides integrated data acquisition and signal conditioning for temperature measurements. The PXIe 4353 includes increased accuracy and synchronization capabilities, making it ideal for measurement systems with scalable channel counts, from low to high channel counts. The module's high accuracy is due in large part to the NI TB 4353 thermostatic junction box, which optimizes thermal conductivity between the thermocouple termination and cold-junction compensation (CJC) channels. The PXIe 4353 has both a 2-way auto-zero channel for offset compensation and thermocouple open-circuit detection for recognizing thermocouple disconnections.
