AUMA Launches Generation .2

The new Generation .2 multi-turn actuator range SA 07.2 – 16.2 and new actuator controls AC 01.2 have been launched by AUMA: the products will be ready for order and delivery from first quarter 2010.

Designed to cater for existing market needs, and next generation requirements, capabilities include the integration of field devices into Asset Management Systems. AUMA has introduced a number of enhanced features and expanded the functionality of its range, while retaining proven design principles. Commenting on incorporating modularity as a fundamental principle of the new products, and additional advancements, Peter Malus, the AUMA Product Manager for the actuators, said:

“The new Generation .2 devices, both actuators and controls, are fully compatible with our previous products: this ensures low-risk investment and guarantees that we will always be at the forefront of technological development.

“Mechanical enhancements improve positioning accuracy, the output speed range of modulating actuators and the extension of the expected actuator lifetime. These advancements are backed by improved corrosion protection.

“One focus of development was to improve device handling. As a result, the handwheel is now activated with one hand by simply pressing a button; valve connection is more flexible and a newly designed electrical connection facilitates the linking of cables with large cross sections. Operation is made easier by a new, enlarged and illuminated graphic display. The display texts are shown in plain text, available in a wide range of languages. Graphic display features are provided e.g. torque curves. Operation, setting, diagnostics and the memorisation of all actuator data is facilitated wirelessly via the AUMA PC ToolSuite.”

Joachim Rist, the Product Manager of the new AC controls, reports that the innovative developments are the result of an intensive exchange between valve manufacturers, consultants, plant operators and control/communication system manufacturers. It was recognised that standards should be followed as closely as possible for all developments outside of the products’ new intelligent functions. For example, the status signals of the AC 01.2 are classified in compliance with NAMUR recommendation NE 107. Consequently, the plant operator receives clearly interpretable signals from the actuators and all other field devices and new diagnostic features of the actuators are supported.

Temperature/vibration sensors and applied torque recording are used to continuously monitor all parameters which contribute positively to the actuator’s life. If an actuator is operated outside the specified operation conditions, for example with an impermissible high number of starts, the plant operator receives advance information enabling appropriate action to avoid malfunction.
In line with AUMA’s previous products, the new controls are available with different fieldbus interfaces, including the Profibus DP interface with V2 services.
