JUMO ecoTRANS Lf03

There where electrolytic conductivity has to be measured in aqueous solutions, transmitters or switches are required with specific features.
By concentrating on the essentials, JUMO GmbH & Co KG, Fulda, Germany, has developed a functional and economical series of devices for application in a wide range of industrial sectors.
Since their introduction at the beginning of this year, the JUMO ecoTRANS Lf01 (with transmitter output only) and the JUMO ecoTRANS Lf02 (switching output only) have been in service in tough industrial applications.
Now the JUMO ecoTRANS Lf03 has been added to this line-up.

Common features of these devices are the method of mounting and the functions that have been integrated.
Combined, these features provide a well-matched functionality for use in general water engineering, such as in monitoring reverse-osmosis or in ion-exchange plant, flushing baths and cooling water applications.
Operating and configuration of the JUMO ecoTRANS Lf03 can be performed through the keypad and the integrated LC display.
Alternatively, this can be done with the setup program that is available.
With the setup program you can also print out the configuration data, thus making it easier to create the increasingly important system and plant documentation.
Conductivity measurement covers the range from
0 — 1µS / cm, using a cell with a cell constant K = 0.01
1 / cm (for ultra pure water) up to 0 — 200mS / cm, using a cell with a cell constant K = 10.0 1 / cm.
Pt100 / Pt1000 resistance thermometers or PTC / NTC sensors can be used as temperature probes.

The following aspects deserve emphasis:
  • two parallel process value outputs (for conductivity and process temperature)
  • switching output
    (relay changeover contact or, alternatively, two open-collector outputs)
  • USP switching function as per USP<645> for use in pharmaceutical water plant
  • temperature compensation for
    natural water as per N 27888
    ASTM D1125-95 (ultra pure water)
    linear
  • electrical isolation between inputs and outputs
    The JUMO ecoTRANS Lf03 offers flexible options for unusual requirements.
