    Product Features

    ACS135 conductivity sensor with measurement range up to 350 mS/cm
    ACS135 conductivity sensor with PTFE housing for chemical-resistant industrial applications

    Conductivity Measurement up to 350 mS/cm

    The ACS135 provides a specified measurement range of 0–350 mS/cm for applications requiring measurement at higher conductivity levels.

    PTFE Housing with Two Electrode Options

    The sensor combines a PTFE housing with either 316L stainless steel or graphite electrodes. This choice allows the electrode material to be evaluated against the process chemistry. Compatibility must account for chemical composition, concentration, temperature and cleaning agents, including all wetted components of the supplied assembly.

    Temperature Measurement for Compensation

    The ACS135 is available with a PT100 or PT1000 temperature element. A compatible transmitter can use this temperature signal to compensate conductivity readings.

    Typical Applications

    • Salt Solution and Brine Monitoring
    • Chemical Process Solutions
    • Industrial Wastewater
    • OEM Equipment and Process Skids

    FAQ

    Should I choose 316L stainless steel or graphite electrodes?

    Choose according to the liquid composition, concentration, temperature and cleaning conditions. Share these details with ARTang to confirm material compatibility.

    Does the ACS135 automatically compensate for temperature?

    The PT100 or PT1000 element provides the temperature signal. Temperature compensation is performed by the connected transmitter using its configured compensation method.

    Can the ACS135 measure salt concentration directly?

    The ACS135 measures conductivity. Converting conductivity into concentration requires a relationship appropriate to the specific solution, temperature and concentration range, together with suitable transmitter or control-system functions.

    Is the ACS135 suitable for pure-water measurement?

    The ACS135 is positioned for applications requiring a high conductivity range. For pure-water or ultrapure-water monitoring, provide the expected conductivity and accuracy requirements so that a suitable sensor and transmitter can be selected.

    Can I connect the sensor directly to a PLC?

    It normally connects to a conductivity transmitter or controller. The transmitter provides the measurement output or communication interface required by the PLC.
