CAUTION: USE THE PROPER PRESSURE MEDIUM. USE ONLY CLEAN,
DRY NON-CORROSIVE GASES. THIS INSTRUMENT IS NOT DESIGNED
FOR OXYGEN USE.
WARNING: NOT EXPLOSION PROOF!
Installation of this instrument in an area requiring devices rated as intrinsically
safe is not recommended.
WARNING: POSSIBLE INJURY!
The tubing, valves and other apparatus attached to the gauge must be adequate
for the maximum pressure which will be applied, otherwise physical injury to the
operator or bystanders is possible.
WARNING: HIGH SOUND LEVELS!
Pressures from 600 psig and up can generate sound levels above 100 db for brief
periods when they are exhausted directly to atmosphere. If no muffling devices are
attached to the EXHAUST port, then ear protection is advised for personnel in
the vicinity of instruments that will be operated under such conditions.
WARNING: HIGH PRESSURE!
High pressure gases are potentially hazardous. Energy stored in these gases can be
released suddenly and with extreme force. High pressure systems should be assembled
and operated only by personnel who have been trained in proper safety practices.
CAUTION: ESD PROTECTION REQUIRED. The proper use of grounded
work surfaces and personal wrist straps are required when coming into contact
with exposed circuits (printed circuit boards) to prevent static discharge to
sensitive electronic components.

MENSOR BACKGROUND
HISTORY: Mensor is an ISO-9001:2000 certified manufacturer of precision pressure products. Mensor
was established in 1969 in Houston, Texas as an independent spin-off from the Texas Instruments (TI)
Pressure Instrument Group. As a private corporation, Mensor’s objective was to design and produce high
accuracy, high quality, easy to use pressure instruments. In 1978 Mensor moved to its present location in
San Marcos, on Interstate 35 (the Austin-San Antonio corridor). Two and a half years after the move, the
plant was destroyed by fire on Friday, February 13, 1981. Mensor resolved to come back, and almost
before the ashes had cooled, construction of a new building began on the same site. Six months after the
disaster, Mensor moved into its present facility and began shipping products to customers who had waited
patiently for the recovery.
PEOPLE: The key to Mensor’s strength in the marketplace is the concentration of experienced people in
the field of precision pressure measurement and control. The company’s founders previously worked in
various capacities in the Pressure Instrument Group of Texas Instruments, including engineering,
production and marketing. These founders were involved in the design of the original quartz bourdon
pressure gauge at TI. Mensor’s CEO, Jerry Fruit, is co-holder of the patent on using a fused quartz bourdon
tube to accurately measure pressure. Mensor employees have an average tenure of sixteen years. That’s a
lot of pressure experience!
PRODUCTS: Mensor’s portfolio of products consists of an extensive line of precision pressure instru-
ments, including digital gauges, pressure controllers, transducers and pressure calibrations systems. All
of these products feature computer interface capability. These products are used in metrology labs,
calibration labs, research facilities, engineering offices, production test stands, and in other environments
were high accuracy pressure measurement and/or control is required. Many of these products include
customized features to meet a customer’s specific requirement. Mensor products range from about $900
to $30,000.
CUSTOMERS: Typical Mensor customers are pressure sensor manufacturers, aerospace firms, jet engine
manufacturers, electric utilities, nuclear power plants, pharmaceutical firms, calibration laboratories,
government agencies and research organizations.
APPLICATIONS: In many facilities the highest accuracy pressure measuring or pressure controlling
instrument is a Mensor product. A typical application for these Mensor instruments is the calibration of
other pressure devices, such as sensors, transducers, transmitters, gauges and pressure switches. The
Mensor product is used as the pressure standard to verify pressure calibrations or outputs of the device
being produced, checked, tested or certified.
