2400 Transmitter

Analog Float & Tape Tank Gauge Transmitter

The GSI 04-20 Transmitter converts level measurement from a standard mechanical tank gauge to a 4-20 mA analog signal compatible with any industrial grade receiver. The GSI 04-20 Transmitter was designed for simplicity of installation and calibration. Its design utilizes only reputable subsystem components to enhance system stability, increase quality, and reduce the number of required replacement parts.

Basic Functionality:  The basic purpose of the GSI-04-20 analog transmitter is to convert the internal rotational motion of a mechanical tape and float level gauge into a 4-20 mA signal representing product level. This rotational motion is available from the mechanical level gauge's output shaft.

Mounting & Application:  The GSI-04-20 analog level transmitter will mount directly to your GSI-2570, or most manufacturers' mechanical gauge heads. When coupled to the gauge head's output shaft the GSI-04-20 utilizes the shaft's rotation to turn a standard 10 turn potentiometer through a precision gear set. The potentiometer's resistance value is then used to establish a variable amplifier gain and thereby derive a 4-20 mA signal. It is housed in an explosion proof (NEMA 7) enclosure and comes with many range options to match a tank height.
