Digital conductivity sensor with IO-Link

October 2018 Sensors & Transducers

Jumo digiLine is the bus-compatible connection system for digital sensors in liquid analysis. The digiLine sensors for conductive (CR) and inductive (Ci) measurement of electrolytic conductivity are new to the range, supplied in a unique variant with an IO-Link interface.

The digiLine range allows for operation of up to six digital sensors on the Jumo Aquis touch S (P) transmitter or up to 62 on the mTron T measurement, control and automation system. Both the operation of individual measuring points, as well as the setup of extensive sensor networks, is possible. Automatic integration into the digiLine sensor network with the intelligent plug and play software tool makes start up easy.

The conductivity measurement devices supplement the Jumo digiLine sensor range, which up until now covered measurements for pH, redox, temperature, dissolved oxygen, turbidity, as well as water disinfection variables such as free chlorine.

The applications are universal with versions available for all water qualities, ranging from ultrapure in pharmaceutical applications, to injection (WFI) quality with conductive values from 0.05 μS/cm to measurements in highly concentrated liquids of up to 2000 mS/cm. Tried and tested analog sensors in the hygienic or standard design type are enhanced with Jumo digiLine electronic components to become intelligent smart sensors.

The Cr/Ci sensors are available with integrated electronic components or detached electronic head and cable connection. The detached version can easily master problematic installation situations, such as heat emission or vibration.

An RS-485 interface with extended Modbus protocol serves as the digiLine interface allowing integration into standard Modbus RTU networks. This is one of the first electrolytic conductivity measurement devices to be integrated in machines and plants with IO-Link infrastructure.
