Why Piezo Sensors Struggle in the Field: The Engineer’s Guide to Agricultural Sensing
Electrostatic ultrasonic sensing gives agricultural equipment one rugged transducer for boom height control, tank level, and grain bin monitoring: detecting soft crop canopy, holding accuracy from -40°C to +85°C, and surviving chemical spray, in conditions where piezoelectric ultrasonic sensors lose the signal.

What Determines How Close an Ultrasonic Sensor Can Detect: Inside the Dead Zone
Minimum range is not a fixed property of a sensor. It is set by the blanking interval the electronics impose — and by whether the transducer stops ringing fast enough to let you shorten it.

How to Measure Snow Depth Accurately in the Field with Ultrasonic Transducers
Electrostatic ultrasonic transducers measure snow depth reliably in unattended installations for weather stations, avalanche monitoring, ski slopes, and hydrology networks — resolving faint echoes off loose powder, […]
