Today Scanivalve Corporation is recognized as the world's
leading supplier of state-of -the art Ethernet-based intelligent
pressure and temperature measuring instruments.
It all began with our founder, JC Pemberton,
working at the Boeing wind tunnel in Seattle, Washington. His
development of a mechanical scanning valve that multiplexed many
pressure signals into one transducer revolutionized the data
acquisition of pressure measurement. At the same time, electrical
strain gauge transducers were being introduced for the first time.
In 1955, JC left Boeing and founded Scanivalve Corporation. News of
the Scanivalve product spread quickly throughout the wind tunnel
industry. Scanivalve also found its way into the gas turbine and
process control industry, expanding and establishing the Scanivalve
name and reputation.
In the following years, besides pressure scanners, Scanivalve
developed a comprehensive product line of more than 3000 items for
facilitating easy pressure & pneumatic connections. These
include small diameter plastic tubing and steel tubulations (.031
inch to .125 inch), as well as a wide selection of pneumatic
manifolds and connectors.
In the 1970's, Scanivalve developed the combination of
calibration valving applied to individual miniature silicon
sensors. The concept allowed computer correction of temperature
errors inherent in these small silicon pressure sensors.
Measurements of the individual sensors were now multiplexed
electronically rather than mechanically, thus allowing faster
sampling rates.They became known as ZOC pressure scanners (Zero,
Operate & Calibrate).
In 1982 JC Pemberton sold the company to his sons,
Addison and Jim. Shortly
afterwards, the PC came onto the industrial scene. Scanivalve
developed the Hyscan2000 pressure measurement system to stay in the
forefront of technology. The Hyscan2000 was a PC-based pressure
data acquisition system capable of sampling pressures up to 100,000
channels per second.
Scanivalve's innovative engineering and sales team looked
forward and saw Ethernet becoming one of the dominant communication
busses for physical measurement. In 1995, Scanivalve relocated to a
brand new manufacturing/headquarters facility located in Liberty
Lake (Spokane), Washington. That same year we introduced our first
Ethernet TCP/IP intelligent 16 channel pressure measurement system.
The model DSA3000 series incorporated not only 16 pressure sensors
but also an A/D, microprocessor, and auto calibration valving to
allow for EU data output.
The model DTS3250 Digital Thermocouple Scanner was a natural
spinoff with our technology. With this model, introduced in 2001, a
user could measure both pressure and temperature quickly,
accurately, and on the same LAN.
As the pace of technology has quickened, Scanivalve has kept
pace. In 2002, a miniature pressure measurement system that is low
cost and easy to use was introduced. It communicated USB and was
called the RAD3200 Remote A/D. As the decade continued this product
was upgraded in 2009 into the ERAD4000 Remote A/D with an Ethernet
100baseT network connection, thus eliminating the USB cable.
These successive new intelligent products have established
Scanivalve as a highly innovative company solving industry
problems. They have helped broaden the industry applications for
Scanivalves beyond just aerospace to include the power industry,
all turbomachinery testing, factory automation, and process
control. Besides company offices in two hemispheres, we have a
trained group of worldwide representatives who can assist you. We
will continue in the future to fulfill our mission, to provide
innovative state-of-the-art measurement solutions to our
