CM14-AAK Endress-Hauser Việt Nam - Tăng Minh Phát Việt Nam

• • Application

    Liquiline CM14 is a 4-wire transmitter with a compact design for mounting in control panels or cabinets. Possible areas of application are wastewater treatment, water preparation and monitoring of drinking water, ion exchangers and surface water monitoring.

    Function

    Sensors for pH/Redox, conductivity and oxygen record the measurement values at the site. These are transmitted digitally to the Liquiline CM14 transmitter using Memosens technology.
    The transmitter converts the signal into an 0/4 to 20 mA signal. In addition to this, temperature can be output as a second current signal. Two limit relays enable monitoring of signals for minimum,
