INSPECTION & HANDLING
.
STAT-probes should be carefully inspected for damage prior to installation. Report damage to your Freight Department,
or contact delivery carrier. Almost any means of handling can be utilized depending on the length and width of the
probes. Probes may be handled while in any position; however, it is important not to drop or mishandle the probes such
that damage is done to the sensing holes, tubular members, signal connection fittings, end studs, or mounting plates.
ORIENTATION OF PROBES
.
Using the AIRFLOW directional arrow on the probe mounting flange to determine correct orientation, install STAT-
probes with sensing holes facing airflow.
INSTALLING STAT-probes
.
To achieve published performance standards, the location of STAT-probes in ductwork must comply with the
Minimum Requirements for Installation
(Page 4). Mounting hole sizes can be obtained using the dimensional
data shown on Page 3.
FASTENERS
. STAT-probe mounting plates and gaskets are predrilled for 1/4" mounting fasteners. For ducts
inaccessible from the inside, Air Monitor recommends Type AB 1/4" thread-forming tapping screws [use a No. 4
(0.209) drill for pilot hole]. If the inside of the duct is accessible, Air Monitor recommends the use of 1/4-20
bolts, nuts, and lock washers (or flat washers and lock nuts). Fasteners should be zinc coated carbon steel, or
better.
Gasket mounting surface should be clean and burr free. Probes should be mounted perpendicular to matting
surfaces. Fasteners need be tightened sufficiently to evenly compress gaskets to about 1/2 original thickness.
