General:

Magtech’s ABM Series Level Transmitters allow simple and reliable non-contact measurement of fluids in a tank, sump or other container. The microprocessor controlled circuit generates a pulse that is transmitted from the transducer face.
This pulse is reflected back from the fluid surface and the transit time is converted into a directly proportional current output.
Because the speed of sound through air changes as air temperature changes, each transducer has built-in-temperature compensation, thus increasing the accuracy of the output. Our proprietary circuit automatically filters out false echos that may be produced by peripheral obstructions in the tank. This unique feature allows the unit to work in a
standpipe over the full operating range.

OUTPUT:
The current output can power a load up to 750 ohms. The output may be proportional or inversely proportional (either 4-20mA or 20-4mA). The output is isolated on AC powered units. Lost echo hold time is 30 seconds then an output of 22mA.
