AM-UST Direct Output Ultrasonic Level Transducer

The AM-UST ultrasonic level transducer is one of the most compact and cost-effective level transducers on the market. Inside a package about the size of a quarter DIN enclosure is a full feature ultrasonic transducer that outputs directly either a 4-20 mA analog signal or two Modbus over RS485 digital signals. The unit is powered by a 9 -36 VDC power supply.

Special microballoon radiating material couples the piezoelectric crystal vibrations into the air with perfect impedance matching. The result is a very narrow beam angle. The embedded software automatically locks onto the true level while filtering out false echoes. Combining impedance matching of the crystal produces a 3 degree effective beam angle.

Simply plug the sensor adapter into your computer and you can program the AM-UST ultrasonic level transducer. To calibrate simply set the empty level and span. This automatically sets the 4-20 mA output.

With no moving parts the AM-UST ultrasonic level transducer will provide years of maintenance-free operation.
