Digital Indication and Control Instrument VarioFox
Nowadays it is hard to imagine complex logistics, production and maintenance processes without efficient communication technologies in areas where production processes have to be run permanently at an optimum rate. But smaller and medium sized companies in particular do not necessarily require network supported process visualization or even 24 hour round the clock manned supervision. This can be seen clearly at hand of an example: For a tank containing organic vegetable oil, an indication of the actual level ranging between 1-30.000 Liters is required locally at the filling device. A combined audible and visual alarm is required as soon as the tank level drops below 250 Liters and a solenoid valve must close when the level reaches 25.000 Liters. At the same time, the user would like to be able to read the oil level at any time on his PC in the office which is located some 23 km away. The Indication and Control Instrument VarioFox from AFRISO was developed for simple applications of this kind, is easy to operate and in conjunction with the AFRISO Event Reporting System EMS 442 and the web-service www.afriso-net.com forms in itself a completely independent measurement and control station with remote monitoring possibilities.

The new Digital Indication and Control Instrument VarioFox from AFRISO 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 linearization is available. The highest and lowest operational values are memorized but can also be utilized 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 Event Reporting System EMS 442 and the web-service www.afriso-net.com 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 visualization, recording or management.
