Description
The specification details for the PXIe-4353, with a part number of 194969E-01L (781348-01), categorize it as part of the SC Express series. This model boasts 32 channels designed for thermocouple input, highlighting its capacity for extensive temperature data acquisition. The device ensures safety and integrity of measurements with an input isolation of 300 V, protecting against potential damage from voltage spikes.
Enhancements in measurement accuracy are provided through 2 auto zero channels and 8 cold junction compensation channels, which are critical for reducing error in thermocouple readings. The device integrates with a TB-4353 isothermal terminal block, specifically designed to maintain temperature uniformity at connection points, further enhancing measurement accuracy.
Data acquisition is conducted in a scan sampling mode, utilizing a Delta-Sigma ADC type to ensure high fidelity in signal conversion. With a maximum sample rate of 90 S/s, the PXIe-4353 is capable of balancing between speed and accuracy for thermocouple measurements. The voltage measurement range is specified at ±80 mV, with a differential input impedance of 20 MΩ, indicating the device’s capability to handle small voltage differences accurately.
The DC linearity of the device is 20 ppm typical, with a maximum of 60 ppm, which signifies the precision of the device in linear measurement scenarios. For troubleshooting and system integrity, the PXIe-4353 features software selectable open thermal couple detection, allowing users to identify disconnected or broken thermocouples efficiently. The input current varies depending on the operational mode, with 17 nA when open thermal couple detection (OTD) is enabled and 400 pA when disabled, showcasing the device’s low power consumption.
Moreover, the PXIe-4353 can handle a channel to channel voltage range
