CR6 Measurement and Control Datalogger
The CR6 measures almost any sensor with an electrical response, drives direct communications and telecommunications, reduces data to statistical values, performs calculations, and controls external devices. After measurements are made, data are stored in onboard, nonvolatile memory awaiting transfer to the computer.
- Operational in extreme environments with a standard operating range of -40° to +70°C and an extended operating range of -55° to +85°C
- Connects directly to a computer's USB port
- U terminals configurable to what you want them to be: analog or digital, input or output
- Supports static vibrating-wire measurements using our patented VSPECT® spectral-analysis technology
- Differentiates even slight changes in data values with high-resolution measurements (to 0.05 µV, 24 bit Adc)
- Contains an onboard CPI port for hosting Campbell sensors and distributed modules (CDMs)
- Directly connects to Ethernet with 10/100 Ethernet RJ-45 or Ethernet over USB (virtual Ethernet)
- Includes a microSD card drive for extended memory requirements
- Provides simple serial sensor integration and measurement with SDI-12, RS-232, and/or RS-485
- Supports full PakBus® networking
- Includes an embedded web page for direct connection via web browser
