Description
The NI SCC-SG01 Strain Gage Module, with the part number 777459-13, is a sophisticated device featuring two Differential Input (DI) Channels designed for a Quarter Bridge Strain Gage Module configuration. This module allows for precise measurements with an input signal range of ±100 mV and is safeguarded by an overvoltage protection mechanism that activates at ±28 VDC, ensuring device safety in both powered on and off states.
It boasts an excitation channel capable of delivering a stable +2.5 VDC excitation voltage with a minimal variance of ±0.4%, along with a current drive of 42 mA2. The module’s performance is characterized by a drift of 13 mV/°C, which is mitigated by the inclusion of a 1.6 kHz lowpass filter for noise reduction and an instrumentation amplifier for enhanced signal clarity.
Furthermore, the NI SCC-SG01 is equipped with a potentiometer specifically designed for nulling bridge-offset, and it operates with a substantial gain of 100 and an input impedance of 10 MΩ. The module also features field-replaceable completion resistors, enhancing its adaptability and ease of maintenance for various applications.
