    Principle of actuation


    The detection part of digital flow sensor utilizes rotation of the rotor (turbine) installed in the passage. The measuring part detects, by means of the external magnetic sensor, the rotational speed of the permanent magnet mounted on the circumference of the rotor.
    You can select NPN output or PNP output optionally.

    • Seizure can be avoided by flow control of lubricating oil for the spindles and bearings of machine tools, printing machines, presses and speed reducers.

    • Tool damage and fire can be prevented by control of coolant flow to machine tools.

    • This sensor is used to check if the filter is clogged or not.

    • Coolant flow control.

    • This sensor has a seven-segment LED digital display to make you read flow rate value easily.

    • You can select one of two different kinds of output types: PNP output or NPN output.

    • This sensor is used with a connector (M12×4-pin).

    • You can use the digital flow sensor with an input power supply of from 12 to 24 V DC (permissible voltage fluctuation ±10 %).

    • The amplifier protection structure conforms to IP67 equivalent.

    • You can set the lower limit of the flow rate. If the flow rate falls below this limit, the red LED lamp (NG) turns on, and contact signal output is given to notify the operator of the critical situation.

    • In the case of low pressure specifications, you can check the flow of fluid by observing the rotor rotation.

    • You can use the sensor at the desired installation position (horizontal, vertical, or tilted position) and in the desired inflow direction.

    • Rotor can be cleaned by air removing the cap from the front of the main body.
