Acculevel - High Accuracy Submersible Level Transmitter
The Acculevel high accuracy level transmitter incorporates microprocessor-controlled signal conditioning to provide outstanding accuracy over temperature. It provides dual outputs, one analog (current or voltage) and one digital RS485. The RS485 connection allows users to retrieve both level and temperature data, interface with a PC, and rescale the analog output from 10% to 110% of the basic range (converter cable and KELLER software required).
This exceptional instrument has been certified to NSF/ANSI 61 and 372 standards for use in drinking water applications. And, on models equipped with 4...20mA analog output, the Acculevel submersible level transmitter also includes guaranteed lightning protection. This internal circuit is included at no additional cost and provides a lifetime warranty against damage from voltage surge.
The Acculevel is assembled in the U.S to customer specifications, including custom pressure ranges and cable lengths.
