Installation Instructions for the
AWM 5000 Series Microbridge Mass
Airflow Sensor
ISSUE 4
PK 88762
Sensing and Control
GENERAL INFORMATION
The AWM5000 Series Microbridge Mass Airflow Sensors
operate on the theory that airflow directed across the surface
of a sensing element causes heat transfer. Output voltage
varies in proportion to the mass of air or other gas flowing
through a given sensor's inlet and outlet ports.
CURRENT SINK/SOURCE
Maximum current ratings are 10 mA sinking and 20 mA
sourcing, governed by an LM224 operational amplifier in the
final stage of the instrumentation amplifier.
MEDIA CONTAMINATION
Media flowing through the sensor should be free of condensing
moisture and particulate contaminants. A 5 micron filter
upstream of the sensing element reduces the risk of damage
due to contaminants.
MOUNTING INSTRUCTIONS
Mount AWM5000 Series sensors with 6-32 screws. The use of
washers below the screw head is recommended. Mounting
torque is 1,1 N m (9.75 in lb) max. for steel screws, or
0,75 N m (6.75 in lb) max. for brass screws.
NOTICE
When making flow connections to a mounted sensor, the
AWM5000 must be supported at the flow adapter.
If end adapters are twisted with respect to the flow tube
during installation, the seal between O-ring and flow tube
will be broken, causing a small temporary leak. The leak
can be as high as 1 psi, or may remain within
specification. It will self-heal as the O-ring conforms.
About 85% of the leak will be gone within approximately
24 hours, with complete recovery within approximately
48 hours.
Do not expose ports to forces greater than 1 kg [2 lb] in a
direction perpendicular to the port centerline.
Torque on ports should not exceed 4,52 N m [40 in lb].
ELECTRICAL CONNECTION
The AWM5000 Series accepts a latch detente connector, such
as:
1. Amp part number 5-103956-3.
2. Sensing and Control part number SS-12143
Information and literature on the latch detente connector is
available from Amp Product Information Center,
1-800-522-6752 or the Customer Hotline, 1-800-722-1111.

Instruction Sheet for assembly procedure
TO MAKE ELECTRICAL CONNECTIONS
1. Remove (unlatch) the connector from the AWM5000.
2. Hand-crimp the interface wire to the appropriate pin on
connector. Suggested tool: AMP Hand-Crimp Tool, part
number 58074-1 and terminating head 58336-1.
3. Insert the terminal contacts into the connector housing after
the carrier strip (lead-frame) is removed.
4. Reconnect (latch) connector to the AWM5000 device.
CLEANING
CAUTION
PRODUCT DAMAGE
Do not use ultrasonics.
Do not use III Tri-chloroethane, methylene chloride, methyl
pyrrolidone or any oxidizing type acid such as formic acid.
Cover the ends of the tube during cleaning because certain
solvents may attack the epoxy which seals the chip tube to
the ceramic substrate.
Failure to comply with these instructions may result in
product damage.
A sevious iniuly.
