Digital conductivity transmitter sensor technology

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. Jumo is cur­rent­ly the only man­u­fac­tur­er in the world that can sup­ply a vari­ant with an IO-Link interface.
The dig­i­Line allows for oper­a­tion of up to six dig­i­tal sen­sors on the Aquis touch S ℗ trans­mit­ter or up to 62 on the mTron T mea­sure­ment, con­trol, and automa­tion sys­tem. Con­se­quent­ly, 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 thanks to the intel­li­gent Plug and Play soft­ware “DSM Tool” makes start­up child’s play.
The con­duc­tiv­i­ty mea­sure­ment devices sup­ple­ment the dig­i­Line sen­sor range. Up until now it cov­ered mea­sur­ands for pH, redox, tem­per­a­ture, dis­solved oxy­gen, tur­bid­i­ty, as well as water dis­in­fec­tion vari­ables such as free chlorine.
The appli­ca­tion area is uni­ver­sal. Ver­sions are avail­able for all water qual­i­ties rang­ing from ultra­pure water in pharmaceutical/for injec­tion (WFI) qual­i­ty with con­duc­tance val­ues from 0.05 µS/cm to mea­sur­ands in high­ly con­cen­trat­ed liq­uids of up to 2,000 mS/cm. Tried-and-test­ed ana­log sen­sors in the hygien­ic or stan­dard design type will be enhanced with JUMO’s dig­i­Line elec­tron­ic com­po­nents to become intel­li­gent, smart sensors.
The dig­i­Line 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 (heat emis­sion, vibrations).
An RS485 inter­face with extend­ed Mod­bus pro­to­col serves as the dig­i­Line inter­face. As a result, the sen­sors can be inte­grat­ed into stan­dard Mod­bus RTU networks.
The Mod­bus ver­sion will be made avail­able at the same time as a dig­i­tal ver­sion with IO-Link inter­face. This is the first elec­trolyt­ic con­duc­tiv­i­ty mea­sure­ment any­where in the automa­tion indus­try that can be inte­grat­ed in machines and plants with IO-Link infra­struc­ture. The com­pa­ny has there­fore devel­oped a clear strat­e­gy for the expan­sion of the IO-Link sen­sor range. Sen­sors for tem­per­a­ture and pres­sure are already available.
