About our Potentiometers:
- Aside from stringent customer requirements, the basic design criteria for our potentiometers
is the military specifications - Mil-PRF-12934 for wirewound potentiometers and
Mil-PRF-39023 for conductive plastic potentiometers. ZERO DEFECTS is the norm rather
than the exception.
- Our potentiometers have continuously supported the defense of the free world. We
could list all the aircraft, missiles, ground vehicles and vessels on which we have
been qualified but this list would be extremely long. In order to offer some insight
to our support of military programs, our potentiometers guide missiles as far back
as Nike to present "black" programs. Aircraft support from F-4, P-3, F-22,
Stealth, C-130, C-135, C-141 and more recently the C-17 and futuristic development.
Helicopters include CH-46, 47, 53, Blackhawk, SOWA, Apache and the Comanche. Our
potentiometers are in space and recon camera controls as well as several commercial
- In the commercial aircraft area, our potentiometers have been certified on the newest
aircraft - C-717 (formerly MD-95).
- Virtually all commercial and general aviation aircraft to some extent utilize our
- We are also a major supplier for segments to the automotive industry, the construction
industry and the agriculture industry.
- Obviously many of our customers have restricted our use of their names as well as
the programs and, as can be understood, we have to keep this confidentiality.
About our Manufacturing and Test:
In order to control our manufacturing schedule and to afford our customers the most
economical product, our machine shop is continuously being upgraded with computerized
equipment. Also our manufacturing and test departments utilize computer controlled
equipment. This equipment allows Servo Instrument to offer expeditious deliveries
for the short run, or proof units to facilitate customer's needs. All the potentiometers
manufactured by Servo Instrument are 100% tested by manufacturing prior to Quality
Control. Quality Control also performs 100% inspection. All first manufactured potentiometers
have an internal First Article test performed prior to completion of additional
units. Where required by the customer a First Article report is supplied with the
first shipment. Many customers require testing to be performed in accordance with
Mil-Std 202, NAS-710, Mil-Std-810 which is also accomplished. It is not out of the
ordinary for some of our potentiometers to be 100% tested at extremely low temperature
which is accomplished and the units are supplied with quantitative data. All inspection
data is retained for a minimum of 10 years. When required, our system has been set-up
to provide complete traceability. This is especially critical for space applications.
As previously indicated, our Quality System is in strict accordance with Mil-I-45208A.
Our system also meets ISO 9001 and AS 9100 requirements. We have also been certified by the FAA.
This is necessary in order that we may continue to maintain our FAA-PMA status for
over 40 different potentiometers. Servo Instrument has been licensed by the OEM's
to support the "after market". There is an FAA designated DMIR on premises
to ensure proper adherence to FAA regulations. The Quality System is under constant
Government as well as internal serveillance to ensure complete compliance with all
applicable quality standards.
