NI cFP-SG-140

8-Channel Strain Gauge Analog Input Module for Compact FieldPoint

  • Measures full-bridge or half-bridge strain gauges, load cells, force sensors, and torque sensors
  • Excitation level (2.5, 5, or 10 V) and filter software configurable per channel
  • 8 input channels
  • -40 to 70° C operating range
  • HotPnP (plug-and-play) operation
  • 16-bit resolution

The National Instruments cFP-SG-140 is an 8-channel input module for direct measurement of full-bridge and half-bridge strain gauges, as well as strain-gauge-based transducers such as load cells, force sensors, and torque sensors. Quarter-bridge strain gauges can be measured using customer supplied external resistors. This static strain gauge module is designed for DC strain measurements in a variety of applications, such as machine monitoring and control in industrial environments and structural monitoring. The NI cFP-SG-140 gives users programmable bridge completion for full and half-bridge configuration and the option to program each of its eight channels with a different excitation level of 2.5, 5, or 10 V. Each analog input channel has a software-enabled comb filter that users can set to reject frequencies above 15, 60, or 240 Hz. Designed from top to bottom for productivity and reliability, the cFP-SG-140 delivers filtered low-noise analog inputs with 16-bit resolution and features overranging, HotPnP (plug-and-play) operation, and onboard diagnostics to ensure trouble-free installation and maintenance. The cFP-SG-140 module comes with a NIST-traceable calibration certificate ensuring accurate and reliable analog measurements.
