Works with following sensors:

For operation with the following sensors:

Designed for operation with devices and mechanisms, where it is necessary to check the presence of swing (slope) of movable parts.

The composition has two sensitive elements for slope recording.

The switching device can be used in industrial enterprises, infrastructure of housing and communal facilities, in hard-to-reach places (wells, basements). The switching device gives a possibility to install control measuring instruments in places with no power supply, operates in difficult climatic and weather conditions.


The switching device is supplied with a 3.6 V power supply.

The power cell of the ROSSMA IIOT-AMS TILT COUNTER switching device is a built-in battery with  capacity of 1200/6000/9000/14000/19000/20000 mAh, designed for a service life of up to 10 years when counting readings and transmitting data once a day.

Counting and summing of tilts number is performed constantly. The package with the counted data is transmitted in wireless network with 1 minute period (it is not recommended to set the discreteness less than 1 minute for a long autonomous operation mode). The read data are stored in the switching device memory.

Data transmission period is configured using special commands in wireless network. By default, the manufacturer sets the data transmission discreteness to 1 time per 15 minutes. The data is transmitted according to the specified timer, which is installed in the internal memory of the switching device.

The switching device is powered by a built-in 3.6 V power supply. 20A/h cell capacity designed for 10 years.

When Prompt for Confirmation option is disabled, the switching device sends the current data to the network with the specified discreteness. There is no package delivery check in this mode. There are no untransmitted packages in the switching device memory.

The switching device communication time is controlled by LoRaWAN network server and can be set by command.
