Wire Production
Manufacturing at Omega starts near the
bottom of the supply chain. The company actually produces its own
thermocouple wire at a manufacturing operation that turns out tens
of millions of feet per year. Starting with bare wire stock in a wide
range of compositions and diameters, finished cable is made for a myriad
of Omega products. Specialized machines turn out braided, extruded,
glass-wrapped, shielded, single conductor, multi-conductor, twisted
shielded pairs, Kapton coated, and PFA coated cable in both solid and
stranded styles. The smallest size used is 40 gauge, which is much finer
than a human hair. Such small gauge sizes are used in many temperature
and pressure sensors, and Omega production personnel have become experts
in handling these super fine wires. If you can think of a wire type, it
is probably made in the Omega facility.
Automation
Omega is a strong advocate of process
automation for both its productivity and quality benefits. It is
used extensively throughout the various manufacturing locations. Where
commercial equipment is used, the input and output processes are often
objects of in-house automation. Omega has some of the most talented
automation engineers around and has invested in the model shops and
labs needed to support them. Working with a talented staff of software engineers,
they produce a wide range of custom automation equipment.
Interestingly, Omega makes extensive use of its own components and
instrumentation products in these automation projects; products that are
also purchased and used by other manufacturers worldwide. This includes
temperature and pressure sensors, load cells, actuators, heaters,
and instrumentation.
Temperature Probes
Omega boasts an automated probe
manufacturing facility that is unequalled. Starting with coils of flat
metal stock and a wide range of wire types, a highly automated
production line fabricates probe sheath, with wiring enclosed, in coils
which can be hundreds of feet in length. Sheath sizes range from an
incredibly thin .010 inches up to a robust .375 inches. While other
manufacturers make the probes individually to a specific length, Omega
can make any desired length by simply cutting it from the probe coil.
The temperature sensor (thermocouple or RTD) is then added to one end,
leads added to the other and the unit is sealed, tested, calibrated, and
ready to go.
Thin Film Fabrication
RTD elements used in temperature sensors
and probes are made in Omega’s own thin film fabrication facility
located in a class 10 clean room. Here the RTD elements are created on
substrates, 2000 at a time, using the latest vacuum deposition and
photolithography equipment and processes. After leaving the clean
room, the elements are laser trimmed to the correct resistance,
assembled into completed sensors with leads attached, tested, and
sorted. While many of these processes are automated, a highly skilled
production team carries out those steps that are best done manually.
From here the completed RTD sensors are routed to other manufacturing
locations for incorporation into a wide variety of end products.
Benefits of In-House Manufacturing
Omega products are used in many critical
applications in manufacturing, food processing, medicine, aerospace, and
science, to name a few. By making the individual components within the
company, Omega can achieve a measure of control not possible when
critical parts are supplied by a variety of vendors with a variety of
reliabilities. Through extensive use of automation and in-process
quality testing, the uncertainties that can be associated with
outside vendors have been eliminated. This is key to the high esteem
Omega enjoys among its customers and its reputation for highly
consistent, top quality products. And, in the event of a problem, you
are dealing directly with the manufacturer who can resolve it.
