• OEM and End User
• High Accuracy
• Compact Package
• Wide Temperature Range
DESCRIPTION
The low cost US300 Series incorporates stainless steel isolation, and provides a wide choice of
standard pressure ranges and electrical outputs in a very compact package. This product uses MEAS’
UltraStable™ technology that provides stability over a wide temperature range, performance previously
available only in much higher priced sensors. The modular design is adaptable to a wide variety of pressure
ports and electrical connectors. Standard outputs include 0 to 10mV/V, 0.5 to 4.5V ratiometric, 1 to 5V regulated
and 4 to 20mA current loop.
