The 2-wire M420 transmitter platform is now extended to inductive conductivity measurement, thus combining the benefits of the proven inductive conductivity sensors of the InPro7250 series with the successful M420 line. The robust InPro7250 inductive conductivity sensors are the ideal solution for demanding industrial applications.
The M420 series features the most advanced measurement technology for operation in hazardous areas, combined with Intelligent Sensor Management functionality for predictive real-time diagnostics. Furthermore, the M420 offers communication capabilities over HART, up to two configurable output signals and a mixed mode input as well as a wide backlit display and a high degree of protection (IP67). Also available are versions for resistive conductivity as well as pH and oxygen measurement.
