DESCRIPTION
The Amphenol Advanced Sensors VaporStat Model
9002 is an absolute humidity transmitter that measures the
amount of water vapor in the air with adversity to temperature
variations. The moisture level is then calculated as dew point
and transmitted simultaneously as 0-10 VDC and 4-20 mA.
A display and keyboard are incorporated for local indication
and parameter adjustment. A contact closure is also
incorporated with keyboard entries for set point and
differential. The Model 9002 is wall-mounted and available
with accessories for duct and OSA applications.
APPLICATION
The Model 9002 sampling chamber measures the infrared
light absorbed by the moisture in the air and processes
it as dew point or grains of moisture per pound of dry air.
The 0-10 VDC or 4-20 mA output ranges are selected at
the keyboard and displayed on the LCD readout. A control
contact energizes at the set point entered on the keyboard.
The Model 9002 is ideally suited for local alarm and signaling
for clean room controls, desiccant system controls, paper mill
controls, and textile process controls as well as condensation
prevention.
