【英文介绍】
National Instruments SCXI-1328 High precision isothermal terminal
The NI SCXI 1328 (Part number: 777687-28) has 18 screw terminals for connecting SCXI-1120, SCXI-1120D, SCXI-1121, SCXI-1125, and SCXI-1126 modules. Of the 18 screw terminals, a pair is connected to the SCXI chassis grounding. For SCXI-1120/D, SCXI-1125, and SCXI-1126, the other 8 pairs of screw terminals are used for signal connection to 8 module inputs. However, for the SCXI-1121, four pairs of screw terminals are used for the four module inputs and four pairs for the module excitation channel. The SCXI-1328 has a maximum field line gauge of 26 to 14 AWG. The NI SCXI-1328 has a DC coupling with an accuracy of 0.5 °C at 15 to 35 °C and 0.9 °C at 0 to 15 °C and 35 to 55 °C.
The SCXI 1328 shielded terminal is equipped with a high-precision thermistor for precise cold-end compensation and an aluminum isothermal plate that reduces the temperature gradient on the screw terminal when the user completes the measurement with a thermocouple. The NI SCXI 1328 has an onboard temperature sensor that measures the ambient temperature inside the terminal. If the user uses a thermocouple to measure the temperature, the temperature can be obtained from an onboard temperature sensor, which can be used for cold-end compensation. To change the voltage reading to temperature, the user can use the thermistor conversion equation. If the user is running LabVIEW, the conversion thermistor VI can be used. If the user is running NI-DAQ, you can use the thermistor conversion function call. The SCXI-1328 can be verified with Fluke 5700A and NI 4060 or HP 34401A. It has a maximum operating voltage of 300 Vrms (for channel-to-ground and channel-to-channel connections).
The NI device weighs 7 ounces and measures 7.0 x 3.125 x 1.2 inches. In the physical dimension. It has a recommended operating temperature range of 0 to 50 °C, a storage temperature range of -20 to 70 °C, and a non-condensing humidity range of 5 to 90% RH.
