Technology

3S actuators are characterized by not only being powerful valve actuators, but by being the only products in the market specifically developed for buried applications. The actuator is installed in a watertight steel casing which is fixed on a patented rotationally locked support plate (“Berliner Kappe”). The whole system is connected via rods with the valve in or near the water pipe. Counter-torques are directly diverted into the surrounding soil an no force-fitting installation or chamber construction is needed on location. 

The core of the technology is the actuator, that comprises the drive unit to operate the valve, a telemetric unit that transmits data including internal control system and different supporting hardware. 

 

The drive, the telemetric unit and connected sensors are powered by a battery and equipped with the patented 3S Energy Save technology which manages power consumption and standby times while ensuring 100% availability of the system with a battery runtime of at least one year. If a valve should be closed the telematics unit receives commands from the SCADA system (supervisory control and data acquisition) of the utility either via a x-active server or directly via DNP3 interface. Due to the availability of the battery pack and telemetries unit, no cabling for power supply or data is needed, further reducing construction costs.

3S actuators feature a CPU capable of evaluating external sensor data (e.g. of the pressure sensors of Oasen), which the telemetric unit of the actuator can transfer to the control centre without additional, external components. Suitable components (hard- and software) need to be developed to interface with the required sensors with a power consumption making the battery-powered operation of the system feasible.

 

Further development of items during the project timeline will be hardware component design (interfaces, choice of micro controller, power supply of components, PCB design and test), software component design (firmware, communication protocols, interfaces), implementation of the 3S Energy Save concept (stand-by, wake-up, boot-up), actuator wake-up in case of sensor data threshold breach.
