Keller U.S.-Built High Accuracy Analog Digital Submersible Level Transmitters
DESCRIPTION
The Acculevel by Keller America provides standard features that far exceed those of comparably priced transmitters, including standard !à0.25% FS or optional !à0.1% Total Error Band (TEB) accuracy.The ability of the Acculevel to provide this level of sustained performance over a wide range of operating conditions, makes it ideally suited to environmental monitoring applications such as surface water, streams, and reservoirs. Keller America!ˉs 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 SS flush-diaphragm sensor standard - Optional titanium for severe ap-
plications. 2-year warranty covers defects in materials 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.
