  • 2. 

    The type 86(7)92/86(7)93 features a transfer element which implements 3 different characteristics.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because it states that the type 86(7)92/86(7)93 features a transfer element that implements 3 different characteristics. This implies that the type 86(7)92/86(7)93 has a transfer element and this element has the capability to perform three different functions or exhibit three different properties.

    What type of characteristic might be best used for liquid level or flow loops?

    • Equal Percentage

    • Linear

    • Quick opening

    Correct Answer
    A. Linear
    Explanation
    Linear characteristics are best used for liquid level or flow loops because they provide a consistent and proportional response to changes in the input signal. This means that as the liquid level or flow rate increases or decreases, the output signal will change in a linear and predictable manner. This is ideal for maintaining accurate and precise control over liquid levels and flow rates, as it allows for easy calibration and adjustment of the control system.

    It is not possible to customize a characteristic.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is incorrect. It is possible to customize a characteristic. Customization allows for the modification or adaptation of a characteristic to fit specific needs or preferences.

    Rate this question:

  • 5. 

    A typical application of an equal percentage characteristic might be:

    • Temperature and pressure control

    • Liquid level control

    • Frequent on/off service

    • DeviceNet control

    Correct Answer
    A. Liquid level control
    Explanation
    Equal percentage valve (most commonly used in valves):
    • Temperature and pressure control loops.
    • Used in systems where large changes in pressure drop across
    the valve are expected.
