Witt Solutions GmbH

WITT SMM 200 is a mobile device to determine the setting/hollow position for up to 5 sleepers. The result is displayed in a LCD and the data is stored internally for subsequent evaluation.

Up to 5 sensors are placed on the sleepers to be evaluated and connected to the device. After the initialization of the device it is in stand-by mode and will wait for a train passage. The setting of each sleeper will be measured as the maximum deviation in the vertical axis in relation to the rest position.

The display always shows the measured maximum of the vertical displacement since the last power on. By pressing the reset button the display can be set to zero and the device is ready for another measurement.

The data is stored internally and can be transferred subsequently via an USB interface and can be evaluated.

WITT SMM 200 calculates from potentiometric voltage values the displacement with an accuracy of 0.1 mm (internally 0.01 mm).

The basis for the sensor mounting is a 40 cm long chisel fixed in the gravel bed. The sensor mounting can be very quickly positioned via a one-button fixture on the respective sleeper. The up to five sensors are individually calibrated end linked with the device via connectors which are associated with a sensor to prevent mix ups. The standard length of the cable is 4 m; other cable length are available on demand.
