    K1800 Digital Tachometer
    Also, this device can be called: K 1800, K-1800, k1800, k 1800, k-1800.
    K1800 digital tachometer is used to measure rotational speed and determine the direction of rotation of the shaft of a gas turbine power plant.

    This instrument K1800 tachometer includes:
    - Tacho G111;
    - The device showing V1500;
    - Meter tachometer digital SCH1480;
    - The direction arrow P161.
           
    The device consists of showing V1500 meter magnetoelectric system V1500 / E and additional device P1820 / P converting the frequency of the generated voltage converter G111 constant current which is proportional to the speed.

    Measuring ranges V1500 and the corresponding frequencies generated tachometer G111 are shown in Table.

    Parameters of the output signals encoded meter load current of 5 mA:
    - A logical "1" corresponds to the voltage 8 ± 0,8 V;
    - A logical "0" corresponds to the voltage less than 0.6 V.
    The devices tachometers K1800 is powered by the AC voltage 127 V and 50 Hz.
