DESCRIPTION

The Amphenol Advance Systems Model GEH3 Series 3%

Accuracy Humidity Transmitters are designed speciﬁcally

for commercial building automation systems (BAS). The room,

duct, and OSA transmitters have replaceable sensor tips

and switch-selectable outputs of 4-20 mA, 0-5 VDC or 0-10

VDC. The GEH3 Series also has an optional temperature

transmitter, which has the same selectable outputs as

humidity. All duct and OSA units come in weather-resistant

enclosures rated for IP42 or NEMA 3R applications.

FEATURES

• ±3% accuracy

• Temperature compensated

• Field-selectable 4-20 mA, 0-10V, or 0-5V outputs

• Replaceable sensor

• Optional temperature transmitter
