The AquaMetrix AM-UST-mini ultrasonic level sensor is a rugged, compact, cost-effective level transducer. It is perfect for level measurement less than 13 feet. Inside the Mini 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 15-24 VDC power supply. The mini satisfies NEMA 4X and IP67 ratings and operates from - 20° C to 65° C with built-in temperature compensation.
With an RS 485 connection to any Windows computer the user can customize both the distance range, offset and span. The software (included) also allows one to adjust the Modbus signal for sampling rate, signal averaging, loss of echo time-out, set-point hysteresis and even view the signal waveform for diagnostic purposes. The multi-drop communication network allows up to 32 sensors to be connected in parallel.
The AM-UST-mini Ultrasonic Level Sensor is ideal for use in the following applications:
- Liquid Level Control
- Viscous or Corrosive Liquids
- Mechanical Positioning
- Automatic Filling Operations
- Paper/Plastic Film Monitoring
- Roll Diameter Measurement
