  • Analog Transmitter AT1000 AT1 - Technical Information

    AT1 analog transmitter is designed to be installed to the LT, and LTC
    series float level gauge. One of the main functions of the transmitter
    is to transmit the level gauge’s signals into voltage, electric current,
    and resistance output signals.
    Because this model has a variety of output signal types, it has an
    extensive connection compatibility with various level setting devices.
    In addition, the alarm and adjustment contact signals are equipped with
    up to six points, enabling the operator to direct the valves andpumps
    with this transmitter alone.

    Technical Information (TI)
  • Analog Transmitter AT1000 AT1 － Operating Instructions

    AT1 analog transmitter is designed to be installed onto LT and LTC
    series level gauging systems. The device transmits the level information
    into electric current, voltage, and resistance signals. It can also be
    equipped with a maximum of six alarm contact signals.
    In addition to transmitting the level, contact signals can be received
    by this transmitter alone, enabling easy control ofthevalve and pump.
