CR-6plus, now a legacy product, was a modern multichannel central monitoring and recording system including a high performance data handling module, providing an extremely flexible 24 Bit multichannel recorder.

Its design was based on years of experience in creating solutions for earthquake, seismic, structural, dynamic and static monitoring.

Its modular architecture and industry standard interfaces offered high versatility, easy expansion, upgradeability, and long term availability of spare parts.

Connection of the sensor cables was extremely easy and fast with the versatile cable screw terminal design. All inputs and outputs of the CR-6plus were protected with a field proven over voltage protection (OVP) system.

Data from acceleration, velocity, displacement, strain, meteorological or any other type of sensors could be monitored and recorded with superior data quality.
 
The CR-6plus continuously monitored the real-time data, which could be recorded based on event detection and continuously. The continuous ring buffer size, the pre-event and post-event time, trigger thresholds and many other parameters were fully user configurable.

In addition to the real-time display of the measured data from each channel the system could provide statistical data such as mean, max, min, and peak values.

CR-6plus could optionally compare the monitored data to four fully independent alarm trigger criteria and provide relay outputs.

GeoDAS, a proven data acquisition and evaluation package developed by GeoSIG, complemented CR-6plus, providing a highly flexible user-friendly capabilities, and graphical, analytical and reporting tools with automation.
 
  • overview

  • CR-6plus is a 19’’ rack module consisting of Slot-in Modules (SiMs) inserted into vertical slots.
    Each CR-6plus rack is expandable up to 36 channels and by combining several CR-6plus systems, hundreds of channels can be monitored.
    System parameters of the CR-6plus are stored in the non-volatile system memory to allow automatic recovery.
  • Sensors

  • The CR-6plus offers the most flexible sensor connectivity options to cater for the needs of any measuring requirement. Any type of sensor complying with the CR-6plus signal input specifications can be connected on the conveniently available screw terminals.
