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.
Reconfiguration is simple with the self-contained Easidew and Pura communications kit.
