Operation
The 8072A is designed to sample process air that is near
atmospheric pressure,
NOT
compressed air. If you are
attempting to monitor compressed air, consult IMS Company
for other model options.
NOTE: For best sensor life and response time, avoid sampling
ambient air of high humidity. Leave unit off when not
monitoring a dryer or hopper.
CAUTION: The carrying case is not heat resistant. It may melt
or distort if left resting on the hot parts of a heated dryer. If a
surface is too hot to touch, it is too hot for the 8072A!
Sample Tubing Connection
To enable testing of your process air, you must provide fittings
in your drying system that will accept the 8072A’s 3/16” ID
sample tubing. This can be a barbed hose fitting or a piece of
¼” copper tube that penetrates your dryer’s air hoses. This
point of attachment must be secure and leak-free. Some dryer
manufacturers provide a port for sampling. Check your dryers
owner’s manual for its location if available.
The sampling tubing supplied with the monitor can tolerate
temperatures up to 275
q
F (135
q
C). Higher process air
temperatures can be cooled to a safe level by sampling through
a few feet of ¼” copper tubing.
Select the sample locations based on your testing needs (refer
to diagram below). It is suggested that you have a permanently
accessible sample point. A barbed fitting with valve at the
output of the dryer is best.
