Dew point or ppmV moisture content output Accuracy ±2 °C (±3.6 °F) dew point MiniDIN 43650 C, M12 electrical connectors Traceable 9-point calibration certificate Power supply 5...28 V DC Ultra-fast response to moisture change Low cost of ownership and easy maintenance with sensor exchange program KF40 Glove Box flange The SF82 is a fast-responding moisture sensor for control of dew-point and moisture content in compressed air dryers to maximize energy efficiency. Compressor rooms are often hot with temperatures reaching +50 °C (+122 °F). The SF82 is capable of reliably providing fast, accurate dew-point measurements down to -60 °C (-76 °F) dew point even in these challenging conditions. The SF82 industrial transmitter incorporates the latest Process Sensing Technologies advanced thick-film polymer moisture sensing technology to provide fast, stable and repeatable humidity measurements for all dew-point dryer applications. It is available with a range of process connections and electrical connectors for easy installation. SF82 dew-point transmitters are included in our service exchange program which reduces both downtime and the cost of maintenance. Suitable Applications Dew-point measurements for: Refrigeration dryers Membrane dryers Adsorption dryers Medical and surgical air Breathing air Additive manufacturing Plastic injection moulding
