DataLogger VKT845
Data Collection Device compatible with New Generation IOT Systems
VKT845 is a device that combines high performance, reliability, stability and accuracy in data collection applications.
In 4 channels Strain Gauge, Loadcell, Extensiometer, LVDT, Transducer, 0-10VDC, 4-20mA, 0-20mA, thermocouple and single channel a 2-4 wire RTD such as Pt100, Pt1000 and a Encoder input upto 1Mhz are processed simultaneously.
It offers automatic or adjustable gain for analog channels, 19-bit resolution depending on sampling rate, and various filter options.
Instantly transmits raw and processed data via wired and wireless, as well as saves to SD card on a real-time basis for later use. The recorded data are transferred to the master device(eg Excel format) using wired or wireless communication.
Its aesthetic and functional structure offers up to 8 multiple uses.
Digital inputs can also be used to ensure that records are synchronized with external events according the user request
With its very low power consumption, VKT845 can easily take place in field applications where solar energy, battery, battery supply can be provided.
