Ultrasonic Sensors in Agricultural Automation
In modern agriculture, sensors are used to reduce labor, increase production, and limit waste. Migatron offers intrinsically safe ultrasonic sensors for silos, grain elevators, chemical tanks and more.
Applications of Ultrasonic Level Sensors in Farming
Non-Contact Level Sensors for Grain Bins
Featured Ultrasonic Sensor: RPS-409A-IS2
Grain bins require continuous, accurate level monitoring to prevent overfilling, optimize storage space, and automate auger control. The RPS-409A-IS2 Intrinsically Safe Ultrasonic Sensor is ideal for this use.
Why RPS-409A-IS2
- Long-range capability (up to 216 inches) fits large storage bins.
- Intrinsically Safe approvals for Hazardous Locations and Explosive Atmospheres.
- Non-contact and durable—suitable for dusty and humid environments.
How It Works
- Mounted on the bin ceiling, the RPS-409A-IS2 monitors grain height in real time.
- Its analog voltage output is fed into a PLC or digital panel meter (e.g., PD6000) for continuous display and alarm settings.
- Calibration flexibility allows farmers to set high/low thresholds for alarms or automate unloading processes.
Stack Height Monitoring for Agricultural Materials
Featured Ultrasonic Sensor: RPS-4000
The RPS-4000 is a strong fit for long-range bulk material measurement because it is designed for level control of both liquids and bulk materials. It also includes signal conditioning to help distinguish real targets from false echoes and electrical noise.
How It Works:
- The RPS-4000 ultrasonic sensor is mounted above the material stack, bin, or storage area.
- The sensor emits ultrasonic pulse toward the material surface and measures the returning echo to determine distance.
- As the stack height increases or decreases, the 4-20mA analog output changes proportionally.
Why RPS-4000
- Up to 40 ft sensing range for larger agricultural storage and material handling applications.
- 4-20mA output works well with common industrial control systems.

Ultrasonic Success Stories in Agricultural Applications
See how Migatron’s ultrasonic sensors solve real-world challenges in agriculture and farming applications:
- A manufacturer wants to maintain a level in the main sugar cane carrier or conveyor.
- They need an ultrasonic sensor with a wide temperature range that can withstand rain, fog, wind, dust, mud, and small waste particles.
- A manufacturer needs to monitor the level of a sand/gravel mixture in a silo.
- They need a non-contact sensor that can be used in an extremely dusty environment.
