What Is Ultrasonic Snow Depth Measurement? Electrostatic ultrasonic sensors measure snow height by emitting a 40 kHz acoustic pulse downward toward the ground, detecting the return echo from the air–snow interface, and converting the round-trip travel time into a distance measurement. Snow depth is then calculated by subtracting that measured distance from the known reference […]

Electrostatic ultrasonic sensors and transducers deliver performance advantages that piezoelectric sensors cannot match—particularly in applications that require long range, soft-target detection, small-object recognition, or stable operation across temperature changes. By leveraging a lightweight electrostatic membrane rather than a heavy ceramic disk, these sensors achieve up to 40 dB higher sensitivity, and maintain consistent performance in conditions

When most engineers think about in-air ultrasonic sensing, they picture a cheap, ceramic “hockey puck” — a piezoelectric transducer. But piezo is not the only option, and not always the right choice. Electrostatic ultrasonic sensors use a different transduction mechanism that delivers higher sensitivity, wider bandwidth, and more stable performance in demanding in-air applications. How

SensComp is proud to announce that one of its electrostatic sensors passed the rigorous testing criteria to be qualified as a component of an upcoming NASA mission to Titan, Saturn’s largest moon. This mission will launch an 8-bladed rotorcraft over 740 million miles to study the fundamental components of organic life on Titan. SensComp’s electrostatic

Electrostatic devices have a higher sensitivity and bandwidth than piezoelectric devices. Electrostatic devices have a relatively flat response over a wide frequency range, and because they are non-resonant, have very low ring-out characteristics. Such devices are more sensitive than their piezo counterparts, typically by 40 dB or better. The increased sensitivity translates into longer-range capabilities
