English version - 01/2014

New version available in English

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.
