PROFINET ACTUATOR RETROFIT IMPROVED PLANT SUSTAINABILITY
How a series of modern actuators were installed in Stockholm’s largest combined heat and power plant
A
uma’s service team has installed 241 modern Auma actuators in Stockholm’s largest
combined heat and power plant, Kraftvärmeverk 1, thus contributing
to sustainable energy generation in the Swedish capital. The high- performance actuators equipped with Profinet interfaces ensure reliable, efficient plant operation and reduced operating costs. The plant was originally built in
1976 for fossil fuels. In 2022 plant operator Stockholm Exergi initiated a large-scale retrofit project to modernise the plant and extend its service life by a further 20 years. Auma’s experienced retrofit experts
helped Stockholm Exergi find the most suitable electric actuation solution for each application. Using Auma actuators with integral Profinet communication brought major advantages: high reliability thanks to integrated redundancy, easy and flexible integration, and advanced diagnostic options.
TRANSDUCER COMES
Technology manufacturer Sensor Technology has updated its TorqSense SGR521 transducer, an enhancement to the company’s TorqSense rotary strain gauge series. In addition to standard digital outputs such as RS232 and USB, the TorqSense SGR521 now features an optional Ethernet output, providing users with enhanced connectivity and data transfer capabilities. It claims that this allows for seamless integration
with various systems and facilitates real-time monitoring and analysis. The SGR series
transducer uses non- contact technology, effectively eliminating the common drawbacks associated with slip rings, and employs modern strain gauge signal conditioning techniques to deliver a remarkable torque measuring solution. With a broad array of
capabilities, the SGR521 transducer offers:
The Auma service team took care of
the entire project management: from a detailed analysis of the requirements, through the selection and sizing of suitable actuators from Auma’s broad actuator portfolio, to installation and commissioning on site. According to the company Auma
offers comprehensive retrofit services, helping plant designers and operators upgrade their existing plants with ‘best-in-class, high-performance valve actuation technology’. A retrofit may become necessary when a new control system is introduced, when new requirements for actuator diagnostics arise, or when manually operated valves need to be automated.
