Pennsauken, NJ, United States, 24th Sep 2025 – H. G. Schaevitz LLC, Alliance Sensors Group (ASG), has announced the release of its new PG Series LVDT linear position sensors, specifically engineered for valve position feedback in turbine valve control systems used in electric power generation plants. At the same time, ASG highlights its S2A Smart AC-LVDT Signal Conditioner, an advanced signal processing solution designed to seamlessly pair with LVDTs and ensure precise, secure, and reliable operation in critical power generation environments.
PG Series: Purpose-Built for Steam Turbine Environments
Traditional LVDTs used in power generation are based on decades-old OEM designs or modified catalog parts that struggle under turbine vibration and heat. The new PG Series overcomes these issues with a rugged, field-driven design developed in close collaboration with power generation controls engineers.
Key PG Series Features:
- Captive core design prevents cores from ever separating from the operating rod
- Large 3/8″ operating rod with optional rigid or ball-joint couplings for easier alignment
- Double-contact shaft seals keep out contaminants in harsh environments
- Screw clamp terminals (No. 24–14 AWG) no fragile connectors to fail
- Continuous operation in ambient temperatures up to 350 °F (175 °C)
The PG Series is available in six full-scale ranges from 0–3 to 0–16 inches (75 to 405 mm). Two construction styles are offered: the PGHD Heavy Duty model (1-1/16″ body diameter) and the PGSD Super Duty model (1-5/16″ body diameter), with optional radiation-certified builds.
S2A Signal Conditioner: CyberSecure and Smart Setup
The S2A Smart AC-LVDT Signal Conditioner is engineered for the power generation sector to deliver fast setup, cybersecurity protection, and extensive diagnostics. It works with a wide range of LVDTs, RVDTs, and inductive half-bridge sensors, including legacy GE 3-wire LVRTs and gas turbine LVDTs.
Key S2A Features:
- Cybersecurity tamper prevention and system notification of tamper attempts
- Color-coded plug-in connections and hot-swap capability
- Extensive self-diagnostics: detects over 11 fault conditions
- Two-year warranty
S2A Operating Benefits:
- Push-button calibration completes setup in minutes
- RS-485 digital communications for remote configuration
- Enhanced fault diagnostics for nuclear- and turbine-grade reliability
The S2A’s built-in microprocessor automates calibration. Operators simply press the front-panel Zero and Full Scale buttons, or use RS-485 for remote setup, reducing setup time by up to 90%.
Designed to Work Together
When paired, the PG Series sensors and the S2A signal conditioner provide a complete valve position feedback solution for steam turbine control systems. The combination delivers rugged mechanical durability plus smart electronic control, ensuring accurate, reliable, and secure operation in demanding power generation environments.
