DESCRIPTION

The Amphenol Advanced Sensors Model GEH2 Series 2%

Accuracy Humidity Transmitters are designed speciﬁcally

for commercial building automation systems (BAS). The

room, duct and OSA transmitters use replaceable sensor

tips and switch selectable transmission including 4-20mA,

0-5V or 0-10VDC. 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.

FEATURES

• ±2% accuracy

• Temperature compensated

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

• Replaceable sensor

• Optional temperature transmitter

APPLICATIONS

• HVAC building controls

• Clean rooms

• Museums / archives
