The FA 515 Ex is a robust pressure dew point meter specifically designed for use in hazardous environments. Its exceptionally wide measuring range from -112°F to 68°F makes it perfect for various industrial applications, including the monitoring of compressed air systems, gases like nitrogen and hydrogen, or environments with high moisture contexts.
This device is engineered not only with precision in mind but also for longevity in harsh environments, certified with an IP 65 protection class and meeting strict intrinsically safe standards for Zones 1 and 21. This makes it an ideal choice for operations in both gas and dust explosion-risk areas.
Specialized Sensor Technology
The FA 515 Ex utilizes advanced humidity sensor technology that has been tested and proven for long-term stability and accuracy across a broad range of temperatures and pressures. Its output, a stable 4-20 mA signal, is compatible with most monitoring systems and ensures reliable and continuous monitoring.
Safe and Robust Construction
Designed to operate safely under potentially explosive conditions, the FA 515 Ex meets all necessary ATEX directives for equipment used in explosive atmospheres. Its robust stainless steel construction prevents corrosion and other wear, ensuring a long service life even in extreme conditions.
