Keller U.S.-Built Preciseline High accuracy analog digital output pressure transmitter
DESCRIPTION
The Preciseline by Keller America pro-vides standard features that far exceed those of comparably priced transmit-
ters by combining proven piezoresistive silicon sensor technology with Keller!ˉs state-of-the-art signal conditioning cir-
cuitry. The result is outstanding !à0.25% FS standard (!à0.1% optional) Total Error Band (TEB) accuracy over a wide com-
pensated temperature range. The ability of the Preciseline 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. User-rangeable analog output ensures compatibility as requirements change. RS485 modified-MODBUS compatible allows up to 128 transmitters on a single bus. Standard dual (analog & RS485) outputs simplify interface to controls, data collection, and telemetry systems. Built in the U.S.A. ARRA Section 1605, Compliant. Standard 3-day lead time at no additional cost.
