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.
A major new introduction to Jumo Instruments' range of industrial process recorders offers all the benefits of paper-free recording without the inconveniences of alternative models Paperless recorders have been available for some time, but have always been expensive, more complicated to use and tend to be larger than other industrial instruments, so do not fit standard slots
The Logoscreen 500 overcomes these problems: it is extremely easy to use and in terms of its size and functions, is a direct replacement for paper recorders.
It offers the largest internal memory on the market, and it can also communicate with external computer equipment for central storage and data analysis.
In addition, it fits the same size slot as a standard chart recorder and, starting at £999, costs far less than most alternative screen recorders - without the cost and time taken to replace consumables such as paper, pens and ink.
For ease of use, the Logoscreen 500's five inch colour display is configured to look exactly like a paper chart recorder - even down to the perforations along the edge of the "paper".
A key advantage of the Logoscreen 500 is the ability to review recorded on the display rather than manually checking through large quantities of paper.
The unit's internal software can search and analyse measured values by date, time or events, and data can also be visualised in different ways to add clarity, such as vertical diagrams, scales, bar graphs, channel labels and event traces.
Set-up is via the eight clearly marked buttons on the front panel of the instrument.
These buttons are used for all operations, providing options for set-up, events, display options and inputting, storing and analysing data.
They also allow users to input their own text into an event list, or to give the recorder a unique name.
Alternatively, the Logoscreen can be programmed by diskette, which fits neatly into the front panel, or via Jumo's newly enhanced PCA software.
Costing less than £100, the PCA software allows data recorded by the Logoscreen 500 to be stored, managed and visualised on a PC running most versions of Microsoft Windows.
This means that process data can be permanently stored and, later, easily located by batch number and quickly re-analysed.
Sections of data can also be cut and pasted into a spreadsheet for further analysis and display in graphical format.
This is a particular benefit in food processing, environmentally critical processes and other applications where accountability is paramount.
The PCA software and Logoscreen 500 combination is particularly powerful when weekly, monthly or quarterly reporting on a process is required.
In this type of application, significant time and cost can be saved, giving a strong payback, which is often needed to justify purchasing.
The data acquisition cycle is every 250 ms, with a minimum memory cycle of 1s and instantaneous display of the recorded value.
Data can be accepted from thermocouples, resistance thermometers or voltage/current signals, and is input via either three or six universal analogue inputs, which are set up by the front panel or using a PC and set-up software.
The Logoscreen 500 is also supplied with its own RS232/422/485 interface, and it can also be networked using Modbus or Jbus (Profibus will be available shortly).
As well as providing the means of communicating directly with a PC, these enable the Logoscreen 500 to act as an analogue input module to a larger system.
This makes it ideal for use in networked data acquisition and batch processing applications.
Few other commercially available, compact data recorder have this degree of power or flexibility.
The Logoscreen fits a 144 x 144mm aperture, and has a front bezel size of 144 x 120mm.
It operates on a low voltage 20-53v DC or high voltage 110-240V AC supply.
Extra options include four logic inputs and three relay outputs.
