New Digital Indication and Control Instrument Offers Cost Effective, 24 Hour Process Visualisation and Management

The new VarioFox Digital Indication and Control Instrument from Afriso (Germany) is a compact, ready-to-connect universal measurement and control instrument with integrated sensor supply and 2 (also choice of 4) voltage-free switching outputs. The instrument is very easy to operate and to program due to its text-orientated menu guidance (German, English or French).

VarioFox features a measurement unit listing, where units can be freely edited, as well as a free scaling/calibration of start and end of scale display values (99.999 - 9,999) which allows for almost all possibly required parameter settings. For horizontal cylindrical and spherical tanks, integrated calibration charts can be accessed. For non-linear vessels or specially fabricated tanks, a customer- specific 24-point linearisation is available. The highest and lowest operational values are memorised, but can also be utilised as instrument-internal visual and audible alarms on request. An alarm mute/accept button on the front of the instrument requires the responsible operator to act and this in itself provides for additional operational safety.

The measuring instrument works off an AC 50-253 V or DC 20-253 V supply and integrates a sensor input (4-20 mA, 0-20 mA, 0-10 V) and two isolated separate analogue outputs (0/4-20 mA und 0-10 mA). VarioFox, in conjunction with the relevant electronic transducers (pressure, temperature, level, humidity) or level switches, provides the user with an easy and quick-to-install stand-alone measurement and control system for the indication/display, processing and the control of process parameters or events. By combining the system with the Afriso’s EMS 442 Event Reporting System and their web-service the user obtains a web-based 24 hour access to all measurement data which he can then tailor exactly to his own requirements with regard to visualisation, recording or management.
