Manual Introduction Thank you for choosing ExpertTM Level Transmitter. On the model 3400 transmitters, the pressure ranges together with the corresponding part numbers are printed on a label on the transmitter housing. We have done everything possible to make a level transmitter that can fulfil all your demands. For all versions the pressure range is indicated on the label. ExpertTM Level Transmitter is suitable for all kinds of level measurements.
Manual Mechanical mounting Model 1400 Cable bracket 1: Mount a suitable hook over the desired measuring location. Note the weight of the cable. 2: Remove the inner conical sleeve from the cable fitting and pull the cable through the outer part. Open the inner sleeve and fit it around the cable at the desired fixation point and press the inner sleeve into place in the outer part. Secure the cable fitting by pulling the cable downwards. Model 1400 3: Lower the pressure transmitter into the wellpipe.
Manual Electrical mounting Designation of wires, cutting & stripping the cable Cable length vs. supply voltage The factory delivered cable has the wires marked with the numbers 1 - 2 - 3 as to the table to the right. If the cable needs to be cutted and stripped, the shield should be connected as the no. 3 wire. The cable can be lengthened with any type of cable using connection box 202922. Although the measuring signal is not sensitive to electrical noise, we recommend the use of a screened cable.
Manual Explosion hazardous zone The insulation between the intrinsic safe circuit and the enclosure withstands 500 VAC. Isolator The KFD0-CS-Ex1.50P isolator (MJK part no.: 202993) which supplies the pressure transmitter through a galvanic separator so neither current nor voltage exceeds the specified limits. Hazardous area Safe area KFD0-CS-Ex1.
Manual Appendices Demands for cables in explosive areas Mechanical dimensions Using the the KFD0-CS-Ex1.50P isolator (MJK order no.: 202993) the max cable length can be calculated. The Cmax and Lmax for the isolator in explosion group IIC are: Cmax : 2,41 μF, Lmax : 4 mH. The capacity of MJK cable type 691005 or 691014 < 800 pF/m and the inductance is < 1,5 μH/m and the capacity and the inductance of the Expert Level Transmitter is Ci = 3,5 nF Li = 7 μH.

Manual Please note the following installation instructions: 1. Follow the installation and safety instructions contained in the Operation Instructions. 2. Install according to the manufacturer’s instructions and other valid standards and guidelines. 3. Do not operate the sensor outside the specified electrical, thermal and mechanical parameters. 4. Install the device only in media for which the wetted materials have sufficient durability. 5.
Manual Data Sheet for Expert™ 1400 Level Transmitter MJK Expert™ 1400 Level Transmitter has about the same specifications as the 7070 model. In addition it has a ceramic, capacitive measuring system with a much higher accuracy. Furthermore, Expert™ 1400 is approved for use in explosion hazardous areas: ATEX Ex ia IIC T6. Model 1400 is very useful for level measurements in for example ground water bore holes and in-fill sites, where explosion proof transmitters are required.
Manual MJK Expert™ 3400 Level Transmitter is designed for use in waterworks, sewage treatment plants and industrial applications where accurate and long term stable level measuring is required. It is very robust and designed for applications in rough environments with aggressive chemicals and aggressive fluids. Data Sheet for Expert™ 3400 Level Transmitter A major design feature is the programming facility.
