Brief description
The JUMO ecoTRANS Lf 01/02 conductivity transmitter is used to measure the conductivity of
liquids in conjunction with electrolytic conductivity sensors.
The instruments are designed for application in general water engineering.
The JUMO ecoTRANS Lf 01 features a freely configurable analog measurement value output.
The instrument can, for example, be used as an economically priced universal transmitter.
The JUMO ecoTRANS Lf 02 is equipped with a changeover relay.
And, using the teach-in connector, the JUMO ecoTRANS Lf 02 can also automatically define the
switching point of the integrated relay.
Typical areas of application are freshwater monitoring and water treatment, reverse osmosis
plant, ion exchanger plant, condensate monitoring, and cooling water checks.
The instrument is programmed via the setup connection (notebook/PC), using the setup
program:
• calibration of the cell constant
• calibration of the temperature coefficient
• configuration of the parameters: range, reference temperature, cell constant, temperature,
switching point, analog output, and others.
Key features
• 3-way isolation (input, output and supply
are electrically connected with each other)
• DIN rail mounting
• 1 electrically isolated analog output
0(4) to 20 mA/0(2) to 10 V
(Type JUMO ecoTRANS Lf 01)
• 1 relay (Type JUMO ecoTRANS Lf 02)
• Teach-in function (definition of switching
point through the teach-in connector) on
the JUMO ecoTRANS Lf 02.
• 1 LED, two colors (red/green), for signaling
operating states
• Calibration timer
• Customized characteristic for temperature
probe can be implemented (e.g. NTC, PTC)
• Reference temperature is settable
