Energy and Power Generation Position Sensors
Power Generation Position Sensors for Steam and Gas Turbine Control
Alliance Sensors Group is the industry leader in power generation position sensing, delivering engineered solutions purpose-built for the demanding environments of steam and gas turbine control. Our PG Series LVDTs and S2A signal conditioner were developed specifically to meet the reliability, accuracy, and long-term stability requirements of power generation applications. Unlike general-purpose sensors adapted for turbine use, ASG products are designed from the ground up to support critical steam valve and turbine control functions, ensuring consistent performance, minimal downtime, and dependable operation in harsh power plant conditions.
The PG Series LVDTs set the benchmark for rugged, high-reliability turbine valve position feedback. Designed as direct replacements for GE and Westinghouse steam turbine LVDTs and inductive half-bridge sensors, PG and LA Series devices incorporate enhanced features including encapsulated cores, double shaft seals, and heavy-duty terminal connections for larger wire sizes. These design improvements provide superior protection against contamination, and vibration delivering extended service life and exceptional measurement stability. Available in single, dual, and tri-redundant configurations, ASG position sensor solutions support both new installations and critical retrofit applications, ensuring seamless integration with existing turbine systems.
Valve Position Feedback for Smart Power Plants and AI Data Center Energy Infrastructure
Accurate and reliable measurement of valve positions is critical for the safe and efficient operation of modern power plants, particularly as the industry moves toward AI-driven, data-centric energy management systems. ASG’s LVDT sensors provide precise, repeatable feedback on valve travel and actuator positions, ensuring that turbine, boiler, and process controls operate with optimal efficiency. This level of dependable measurement enables real-time monitoring, predictive maintenance, and data analytics that are essential for next-generation AI data centers and smart power plants, helping operators reduce energy waste, improve system responsiveness, and confidently plan for the future of energy infrastructure with maximum reliability.
Smart S2A Signal Conditioner with Cybersecure Lock to Prevent Tampering
Complementing the PG Series LVDTs is ASG’s S2A LVDT signal conditioner, engineered specifically for power generation control environments. The S2A provides precise excitation, amplification, and signal conditioning for LVDTs, half-bridge sensors, and GE gas turbine buck-boost LVDTs, delivering highly stable, low-noise outputs essential for accurate turbine valve positioning. Built for continuous-duty operation in high-temperature and high-vibration environments, the S2A ensures reliable signal integrity across long cable runs and harsh power plant conditions, making it the trusted choice for mission-critical turbine control systems.
Trusted Power Plant Position Sensing Solutions with Expert Engineering Support
With decades of application expertise, ASG goes beyond supplying components by delivering complete, application-driven sensing solutions. From direct replacements for GE and Westinghouse designs to custom-engineered configurations, ASG supports every stage of the project lifecycle with expert application engineering, fast response times, and proven field performance. This combination of industry-specific design, superior product reliability, and dedicated technical support has made Alliance Sensors Group, the trusted leader in power generation position sensing, helping plants worldwide achieve safer, more reliable turbine operation and more efficient.
ASG also offers GE gas turbine LVDTs (pt# 311A5178), GE steam turbine LVRTs (pt#s 119C9638, 119C9639, and 196C8768) and Westinghouse LVDTs (pt# 738J204).
