This high-precision dew point sensor is ideal for all types of adsorption dryers, featuring a wide measuring range of –80 to +20 °Ctd. It provides gas-independent measurement, making it suitable not only for compressed air but also for other non-corrosive gases.
Its compact design allows easy integration into dryer installations, while the robust IP66-rated housing ensures reliable operation in harsh industrial environments. The sensor element is condensation insensitive, offering excellent long-term stability and drift resistance, which helps optimize calibration intervals and reduce maintenance effort.
Fast response times—especially during transitions from dry to wet conditions—ensure accurate and dependable monitoring of dew point levels. Multiple thread and output options support flexible system integration.
