Honeywell's extensive line of DL4000 conductivity cells is compatible with the DL423 Sensor Module. These cells are ruggedly constructed for reliable, continuous measurement of electrolytic conductivity up to 140ºC and 250 psig.

The DL4000 line of conductivity cells are used with the DL423. An integral or remote configuration is available, depending on the process installation.
The integral conductivity cell design can be used for in-line and flow cell types of installations. For immersion or ball valve mountings, a remote cell design is required. The remote cell design employs a cable integral to the cell that is connected to the DirectLine® Sensor Module.

The conductivity cell bodies are constructed of PolyEtherSulfone (PES) for excellent corrosion resistance in a wide range of applications. Cell constants are available for applications ranging from ultrapure water to acid/base concentrations.

DL4000 Conductivity Cells have an EEPROM with the cell constant and cell calibration factor programmed into it.

These values are automatically uploaded into the DirectLine Sensor Module. This eliminates the need for the user to manually do this and reduces configuration errors.
