Measuring device to test completely installed insulated rail joints safely and contactless with direct resistance indication

No longer a non-defective joint will mistakenly be displayed as defective No more mistaken removal of faultless joints The SICO 2046 does not indicate a faulty joint with colored LEDs or dial pointers as older rail joint testers do, but it indicates the authentic resistance of the insulated rail joint It can store the measured results in the tester According to already existing insulated rail joint testers, the joint is defective when the displayed resistance is <10 Ohm

In comparison to older testers the Insulated Rail Joint Tester SICO 2046 offers an innovative solution providing true resistance measurements from insulated rail joints. The solution is a current measurement with a separate current sensor, which is wound around the rail joint. Only the current through the rail joint is measured. Parallel current paths close to the insulated joint won’t distort the current measurement. Thanks to its elaborate measuring principle the tester separates the current flow from external portions, e.g. current from the impedance bond, connecting line or ballast, and distinguishes between the actual resistance of the joint and parallel loads. The voltage is measured contactless, too; the resistance of only the rail joint is identified. Even in case of rail to rail short circuits the SICO 2046 displays a result of >50 Ohm, when the joint is not faulty.

The SICO 2046 displays a result of >50 Ohm even in case of parallel short circuits, when the joint is not faulty. Furthermore, bridged rail joints can easily be tested without the removal of connecting lines.

The user can easily simulate the measuring result with help of a test resistor. Always the result of the test resistor in Ohm is displayed.

The SICO 2046 can be operated at any type of signal plant and insulated rail joint.

Tester The tester is the main part of the system SICO 2046. It has a graphic display, which reports measuring results and instructions for the user in different languages. The robust plastic housing with its large keys ensures a convenient operation during all outdoor measurements. A display heating ensures the operation of the tester also at temperatures below -15 °C. To save energy the tester shuts itself down automatically after some minutes of inactivity.

Generator and C-sensor The generator supplies the measuring object with energy. It shuts itself down automatically after a few minutes of inactivity. The C-sensor provides the measuring system with the current result of the tested insulated rail joint.

V-sensor Bottom The V-sensor provides the measuring system with the voltage result of the tested insulated rail joint. It measures the voltage contactless. Magnets in the high insulating plastic film help to have a good permanent mechanical contact to the rail.

Installation Quick installation: Place the V-sensor in the middle of the insulated rail joint, Loop generator and C-sensor around the rail, Connect V- and C-sensor with the tester and Switch on the tester. The measuring result is displayed immediately.

Installation of the C-sensor 1. Plug connection of C-sensor 4. Ready to operate C-sensor 2. Pull one end of the C-sensor under the rail 3. Plug together both ends of the C-sensor

Positioning the C-sensor Wrong Correct The C-sensor must be located before the next conductor branches off (view right picture above). The C-sensor shall only be bent around the rail or the joint (view right picture at the bottom) and must not include further conductors (view left picture at the bottom).

The direction in which the handles of the two coils are pointing is irrelevant for the measurement. They can either be placed on the rail head or pointing to the side (view pictures).

Test Resistor With help of the test resistor 33 Ohm the user can prove the correct display of the measuring result. Thus, the measuring result can be referred to a reliable reference.
