Description

The Sefram 8460 is a High-Speed Thermal Chart Recorder for: Voltage, Current (with shunt or Clamp), Temperature (thermocouples), measurements on sensors (e.g. 0-10V; 4-20 mA), etc..

One of the benefits of the 8460 is that it is a modular system, with 4 input boards available:

Another feature of this system is that it is possible to record 6 up to 36 channels, and 16 logical inputs. Additionally, long term measurements with a sampling rate of 1MHz are possible with the 500GB internal hard disk memory. Also, with a special integrated function of Power Analysis you can record all your parameters on a Single-Phase and Three-Phase network (50Hz, 400Hz and 1kHz).

Furthermore, this Data Acquisition System can be remotely controlled by USB, Ethernet or Wi-Fi connection and the results can analysed on license-free software from Sefram.
