KELLER Launches 20SX Series: Precision-Optimized for Industrial & Energy OEMs

The KELLER 20SX series pressure transmitter heads, engineered with threaded connections, are purpose-built to excel in demanding OEM environments where reliability and precision are non-negotiable. By merging the robust 20S pressure transmitter design with KELLER’s cutting-edge X-line electronics, this hybrid innovation delivers unparalleled accuracy, exceptional long-term stability, and resilience against extreme overpressure conditions—all hallmarks of KELLER’s commitment to industrial excellence.

Unlike competitors that reserve advanced features for premium tiers, KELLER integrates cutting-edge capabilities as standard across its 20SX lineup. The compact, fully hermetically sealed construction houses state-of-the-art digital compensation electronics, enabling real-time calibration of thermal and mechanical inaccuracies via a sophisticated mathematical model. This approach ensures ultra-tight total error bands (TEB) and measurement precision that redefines industry benchmarks.

Tailored for industrial automation, oil and gas extraction, and process control systems, the 20SX series extends KELLER’s OEM portfolio with a modular design philosophy. 

Dual-Interface Flexibility: Seamless integration of RS485 digital communication with analog output, allowing hybrid system integration without hardware redesigns.

Dynamic Scalability: Analog range adjustments via RS485 (turn-down ratio up to 10:1), enabling real-time configuration for evolving process demands.

Modbus RTU Integration: Bidirectional process data exchange and parameter tuning via standardized Modbus protocol, streamlining system integration.

Zero-Drift Stability: Proprietary drift-compensation algorithms ensure consistent accuracy over 10+ years, reducing maintenance cycles and lifecycle costs.

"The 20SX series embodies KELLER’s philosophy of delivering future-proof technology as standard," said [Spokesperson Name], Head of Industrial Solutions at KELLER. "By embedding advanced diagnostics and scalability into our core design, OEMs can now deploy systems that adapt to tomorrow’s challenges—today."

With its compact footprint, plug-and-play Modbus compatibility, and decade-plus longevity, the 20SX series positions KELLER as a leader in empowering industries to transition toward smarter, more resilient automation networks.
