This high-precision dew point sensor is specifically designed for refrigeration dryer applications, offering an accuracy of ±1 °C within a measuring range of –20 to +50 °Ctd. The sensor provides gas-independent measurement, making it suitable not only for compressed air but also for other non-corrosive gases.
Its compact and robust design makes it ideal for integration into dryer installations, even in demanding industrial environments. The sensor features a condensation-insensitive sensing element, ensuring reliable operation and long-term stability with minimal drift, thereby extending calibration intervals and reducing maintenance costs.
Fast response times—particularly during transitions from dry to wet conditions—ensure accurate and timely measurement. Multiple process connections and output options allow seamless integration into existing systems.
