Keller U.S.-Built Valueline High Accuracy Pressure Transmitters
DESCRIPTION
The Valueline by Keller America provides standard features that far exceed those of comparably priced transmitters by combining proven piezoresistive silicon sensor technology with Keller! state-of-the-art signal conditioning circuitry. The result is outstanding !à0.25%. FS standard (!à0.1% optional) Total Error Band (TEB) accuracy over a wide compensate temperature range. The ability of the Valueline to provide this level of sustained performance over a wide range of operating condi-
tions makes it ideally suited to pressure monitoring applications such as tank level measurement, pump control, and
VFD control. Plus, guaranteed lightning protection makes this transmitter ideal for installation in areas prone to chronic
damage due to transients caused by lightning.
FEATURES
4...20mA models include guaranteed lightning protection at no additional cost. 16-bit internal digital error correction for
cost-effective low Total Error Band (TEB)316L stainless steel construction 2-year warranty covers defects in mate-
rials and workmanship. Standard outputs simplify interface to controls, data collection, and telemetry systems.
Various electrical connections for easy integration into new and existing systems.
Cabled versions are rated IP68 and suitable for submersion.
Built in the U.S.A. ARRA Section 160 Compliant.
Standard 3-day lead time at no additional charge.
