Preciseline High Precision Pressure Transmitter

Be the first to review this product

Availability: <1 Week


Quick Overview

±0.2% FS or ±0.1 FS total error band, 316 SS construction, custom pressure ranges up from 2 to 15,0000 PSI, with RS485 output.

The Preciseline by Keller America combines a stable, media-isolated sensor with the most advanced error correction electronics available in such a compact envelope. True 16-bit error correction, updating the analog output at 200Hz, provides real Total Error Band performance that delivers consistent results over a wide range of operat- ing conditions. As well as the analog output, the standard Preciseline provides an RS485 interface, affording the user the ability to monitor both pressure and temperature from up to 128 transmitters on a single bus, in addition to providing a means by which the analog output may be rescaled. Keller America’s guaranteed lightning protection makes this transmitter ideal for installation in areas prone to chronic damage due to transients caused by lightning.
