The Omega CDTX680 Series Contacting Conductivity Two-wire Transmitter is a loop-powered device that uses a CDE680 series enhanced performance contacting conductivity sensor to measure conductivity in solutions. It can be used with sensors that have a 0.05, 0.5, or 10.0 cell constant. The measuring range of this transmitter is factory-set to a user-specified range, but can be changed in the field if desired. Some of the features of this transmitter include:

• Automatic temperature compensation from 32 to 212°F (0 to 100°C) with an adjustable slope from 0 to 4% per °C
• 0.1% of span sensitivity and 0.1% of span or better repeatability
