The intelligently networked successor to the ARIS Tensor, which is widely used in plant engineering, offers a fantastic range of options. In the actuator segment, it radically alters the principle and scope of upgradability with additional functions for economical use in connected infrastructures.

In addition to maintaining the full range of functions of its popular predecessor, the Tensor 2 also features a CAN bus as a serial industrial connection to higher-level control systems and a Wi-Fi module for operation in areas of the plant that communicate wirelessly. The operation of the actuator has been thoroughly revised and simplified. In place of the classic 7-segment display, the Tensor 2 has an intuitive, graphics-based display with various operating modes and the option for user-specific, programmable operation. The range of functions offered by the Tensor 2 reflects the needs of industrial practice: based on more than 40 years of special-ised experience in actuators, ARIS has developed and produced the Tensor series from Troisdorf in close cooperation with plant manufacturers and operators.

CAN bus – Industrial Internet of Things
Each Tensor 2 is equipped with a CAN bus ex works for wired communication with the control system of the plant, which can optionally be activated to allow individual control. The tech-nology for data readout and communication with the control system is present onboard every unit and can also be purchased post-installation if required. No further hardware is required for activation and there are no transport times for additional modules with an activation code. This allows the Tensor 2 to be installed at a very low cost and means that it is prepared for any subsequent system upgrades right from the start.

Wi-Fi – Wireless control on the virtual network
The Tensor 2 is also suitable for wireless use in modern systems. If required, an optional Wi-Fi module can be plugged in to connect the actuator to its system via a virtual network. This al-lows for parameter changes to be made during operation, among other things, even in areas of the system that are difficult to access.

One of a kind for its size: Optional signal contact
The Tensor 2 can also transmit data about its operating status directly to a control unit via an optional signal contact, which allows the system to be more precisely regulated from the cen-tral control room. Using the reported data, it is possible to flexibly adjust the operation of the Tensor 2 over a period of time to ensure full functionality even if physical conditions change or the runtime is long.

Multi-faceted game changer for the IIoT
The actuator parameters of the Tensor 2 (torque and positioning time) can be adjusted by the user to suit specific applications. The compact design of the Tensor series actuators and their relatively low engine power make them particularly flexible: using a table, optimised value pairs that operate each direction of rotation separately can be selected for the Tensor 2. This allows for task-specific control loops to be optimally set up and adjusted. The ARIS Tensor 2 can operate on mains standards from 85-265 volts without the need for any further modification and is therefore internationally compatible. As an actuator for intelligently networked use, it is available on the market since the second quarter of 2021.
