ISL 05x Inductive Conductivity Transmitter Safety instructions This instrument is built and tested according to the current EU-directives and packed in technically safe condition. In order to maintain this condition and to ensure safe operation, the user must follow the hints and warnings given in this instruction. During the installation the valid national rules have to be observed. Ignoring the warnings may lead to severe personal injury or substantial damage to property. The product must be operated by trained staff. Correct and safe operation of this equipment is dependent on proper transport, storage, installation and operation. ISL052 All electrical wiring must conform to local standards. In order to prevent stray electrical radiation, we recommend twisted and shielded input cables, as also to keep power supply cables separated from the input cables. The connection must be made according to the connecting diagrams. Before switching on the power supply take care that other equipment is not affected. Ensure that the supply voltage and the conditions in the environment comply with the specification of the device. ISL051 Before switching off the supply voltage check the possible effects on other equipment and the processing system. WARNING This product contains no replaceable parts. In case of malfunction the product must be shipped to Baumer for repair. Functional Principle A AC Proc. D D 2 1 A 3 2 1 4...20 mA outputs 4 www.baumerprocess.com Design and specifications subject to change without notice Inductive conductivity measurement is based on the principle of two series-connected toroidal-core transformers (1) and (2). The primary side of the transformer 1 is controlled by an AC voltage generator. The liquid flowing through the channel bore (3) in the measuring head form a conductor loop, which links between the secondary side of the transformer (1) and the primary side of the transformer (2). The output current is proportional with the conductivity of the media. Signal conditioning, amplification and conversion provides a 4...20 mA signal output from the galvanically isolated D/A converter. The measured conductivity is highly dependable of the media temperature. Therefore the fast-response temperature sensor in the tip (4) compensates for the temperature in the media. The special processing unit offers maximum accuracy and reliability. The very low resolution of 1µS/cm together with a fast response time gives a high sensivity. This ensures reliable detection of media even with minor differences in conductivity, such as different kinds of beer. Installation Manual Page 1 Mechanical Installation Dimensional Drawings Welding part Please refer to “Accessories” data sheet. The welding part has an engraved mark or hole. When the product has been mounted and correctly tightened the gland or M12 plug will align with this mark. Make sure that the gland/plug is pointing downwards to prevent fluids from penetrating into the instrument. [mm] ø89 98 M12plug M16 AF36 Cautions Use only the authorised special designed accessories. The product warranty is void when installed with other adapters. Do not use teflon, paper or other gaskets. G1 35 ø6 Channel boring L Mount the hole at the sensor tip in the direction of the media flow. 26 Temperature sensor tip It is not possible to turn the display relative to the channel bore. After carefully insertion of the sensor into the welding part tighten the union with a torque of 20...30 Nm. ø25.5 After Installation and Configuration Insert length L = 40: Standard sensor shaft Insert length L = 87: Extended sensor shaft Check the leak tightness of the sleeve. Check the tightness of glands or M12 plugs. Check the tightness of the cover.

Both 4...20 mA outputs are galvanically isolated from the power supply. Terminals 4 and 6 are internally connected. 24V control signals (pnp) can be connected to terminals 7 and 8 for remote selection of one of four measuring ranges. All four measuring ranges can individually be set to a range according to the table.

Push Left/right Push to set Note 3 Calibration of the ISL This procedure describes an easy procedure for determination of the temperature coefficient (TC) of a media. 1. Dip the measuring head in a sample media making sure that the channel bore is completely covered with media without bubbles. 2. Heat the media to 25.0°C 3. Ensure adequate circulation in the media. 4. Note the indicated conductivity. 5. Heat the media to min. 60°C 6. Set the TC in the setup menu to indicate exactly the same conductivity as it is at 25°C. Warnings: 1. A higher TC value will result in a lower conductivity indication. 2. Do not use the TC value to adjust a measured value. The instrument has been calibrated from the factory. 3. Inadequate circulation in the media will cause a slight heating of the channel bore resulting in a false measurement. www.baumerprocess.com Design and specifications subject to change without notice Note1: After 60 seconds without any action from the user the instrument switches back to normal mode indicating the actual measured values. Note 2: Each of the four measuring ranges is assigned its own setting for temperature compensation. The compensation is adjustable in the range 0.00...4.98%/K. The compensation is defined as being linear at 25°C. Note 3: Selectable temperature ranges: 0...150, -20....130, 0...100, -20...80, 0...50, -10...40, -20...150°C Installation Manual Page 4 5850-005_UK/2007-10-02/Rev.
