NEW: level data-logger by KELLER

This data sheet specifies the additional conductivity measurement function which distinguishes the CTD version from the standard DCX-22 product line. The pressure and temperature specifications are set out in detail in the data sheets for the DCX-22 AA and DCX-22 (SG/VG).

Conductivity is increasingly being monitored in conjunction with depth measurements, in which changes in water quality and depth are required to be detected simultaneously. Thus it is possible to detect contamination caused by salt water infiltration, waterborne particles or general pollutants when measuring groundwater levels.

KELLER''s Logger 5.1 programming and readout software is used to select a conductivity range (0…0.2 mS/cm, 0…2 mS/cm, 0…20 mS/cm or 0…200 mS/cm) and set the temperature coefficient for the medium. This process produces compensated conductivity measured values standardised at 25 °C

New KELLER transmitters for automation technology with IO-Link and CAN-Open interface

For smooth integration and operation in automation systems

The compact pressure transmitters of the 21Zio series can be used both as a pressure measuring instrument and as a pressure switch. Thanks to the universal IO-Link interface according to IEC 61131-9, the sensor is flexible and easily and quickly integrable into intelligent automation and other systems. The switching functions and other parameters can be called up and con...
