Amphenol 2% Wall, Duct and OSA Humidity Transmitters GEH2 Series

Amphenol 2% Wall, Duct and OSA Humidity Transmitters

 

The Amphenol Advanced Sensors Model GEH2 Series 2% Accuracy Humidity Transmitters are designed specifically for humidity measurement for commercial building automation systems, BAS, and HVAC applications. The room, duct and OSA transmitters use replaceable humidity sensor tips and switch selectable transmission including 4-20mA, 0-5 volt or 0-10 volt DC. The GEH also has an optional temperature transmitter output with selectable outputs (RH&T must be the same type). All duct and OSA enclosures are rated for IP42 or NEMA 3R applications.
