Model ADHT-Ex

Intrinsically Safe 4-20mA Dewpoint Transmitter.

Ranges available between -110 °C to +20 °C (-166 °F to +68 °F) dewpoint

The Alpha Moisture Systems Model ADHT-Ex is a 3 wire, 4-20 mA, 24V powered

dewpoint transmitter. The unit is fully self contained in a robust stainless steel

casing with weatherproof protection to IP65, making it ideal for use in heavy

industrial environments.

Designed with the operator in mind, Model ADHT-Ex is extremely easy to use and

the digital dewSMART™ technology ensures accurate and reliable readings with

little or no maintenance.

Fast Response - Stable - Reliable - Accurate -

Easy to Install.

Model ADHT-Ex is certiﬁed intrinsically safe to

for use in hazardous areas using a signal isolator PR5104BB2A (recommended) for 100 to

240 VAC (24 VDC to special order). See illustration below.

Various ranges are available covering an overall range from -110 °C to +20 °C dewpoint. The Model

ADHT-Ex derives its power directly from the signal isolator and it is conﬁgured to give a linear 4-20 mA

signal for the chosen range.
