Paperless recorder features single-knob
operation
The Jumo Logoscreen nt is the latest in paperless recorders, with proven functions retained and new functions implemented.
The Jumo Logoscreen nt is the latest in paperless recorders, with proven functions retained and new functions implemented Easy-to-use operation of the instrument and the PC software components, high measurement accuracy (particularly for thermocouple measurements) and high noise immunity were at the forefront during development of the Jumo Logoscreen nt

Entry level price for well-featured controller
The iTRON family of microprocessor controllers from Jumo Instruments is designed for people needing a controller with a rich array of functions at an entry-level price.
Paperless chart recorders get affordable
The Jumo Logoscreen 500 fits the same size slot as a standard chart recorder and, starting at £999, costs far less than most alternative screen recorders.
For applications in security-sensitive areas, due attention was paid to criteria such as tamper-proofing and tractability of the stored process data.
One particular highlight is the way in which the user can operate the Jumo Logoscreen nt through just one control element, by being able to call up every function of the instrument by rotating and pressing the control knob.
The basic version of the Logoscreen nt is fitted with three or six analogue measurement input channels, and the three-channel version also includes eight binary I/Os, an error-signalling relay, as well as an RS232/485 and an Ethernet interface.

The latest in Jumo Instruments' highly successful dTRON microprocessor controller series is now sealed to IP65, making it particularly suitable for laboratory, medical and sterilisation applications
The number of inputs and outputs can be expanded through plug-in modules up to a maximum of 18 internal analogue inputs, thus enabling adaptation to the requirements of the system operator.
And, in addition to the internal measurement inputs, up to 24 measurement inputs can be implemented externally.
The Logoscreen nt handles all the usual sensor signals (current, voltage, thermocouples, and resistance thermometers) with a 125ms minimum sampling cycle time.
All measurements can be saved in up to nine groups, with various storage cycles.
Another feature of the Jumo Logoscreen nt is the ability to register data from different processes or batches simultaneously, but independently of one another.
For example, up to three batches can be started and stopped, displayed and monitored, at different times.
Keen savers will like this, since it means that, according to circumstances, up to three normal recorders can be replaced by a single Jumo Logoscreen nt.
The Jumo Logoscreen nt expands the usual visualisation options available in typical paperless recorders, such as traces, bar graph display, or textual information, with the option of a process diagram presentation.
Users can create their own process diagrams and implement them in the instrument.
Up to 12 measurements can be shown within these process diagrams.
Not only can the new paperless recorder have an enormous number of measurement inputs (up to 18 internally and 24 externally) and binary I/Os (up to 24 internally and externally) but it also offers these features: 27 counter/integrator channels and nine maths channels can be activated; the user menu for the instrument is available in a number of languages (English, French, German, Russian, Chinese); the instrument can be fitted with a Profibus interface and a connection for a barcode reader; it can also be used as a Modbus master, and offers the possibility of storing customer-specific HTML pages.
