1. Introduction: Why Does “Inversion” Happen? Inversion Is Not a Sensor Failure—It’s a Misalignment of Conventions In industrial automation, determinations such as “object present/not present” and “in position/not in position” are typically implemented using discrete (switching) sensor outputs and connected…

1. Introduction: With the Same Ultrasound, Why Can the Ranging Results Differ So Much? When engineering teams evaluate ultrasonic ranging solutions, they often notice something surprising: even when the sensors/transducers are all based on ultrasound, the results can differ significantly…

1. Introduction: Why Frequency + Blind Zone + Crosstalk Decide AGV Obstacle-Avoidance Reliability For AGVs, “seeing an obstacle” isn’t enough—what matters is whether the system can detect it early and consistently, especially in the near field where the safety margin…

1. Introduction Accurate liquid level measurement is essential for many industrial applications, including storage tanks, water tanks, chemical tanks, slurry tanks, wastewater systems, and wet-dry feeders. Whether the goal is to prevent overflow, protect pumps, monitor material consumption, or improve…

Ultrasonic transducers are the core components that enable ultrasonic measurement and detection. Through electroacoustic conversion, they establish the link between electrical signals and ultrasonic waves in a medium.In this guide, the ISSR engineering team explains (from an applications-and-design perspective) what…

1. Introduction What Short-Range Detection Is “After” “Short-range detection” is often misunderstood as “since the distance is not far, the requirements are not high.” But in parking and blind-zone assistance scenarios, it is the opposite: the challenges often concentrate in…

Wind speed and direction data are indispensable environmental parameters in meteorological monitoring, wind power generation, marine navigation, bridge safety, highway early warning systems, smart agriculture, and industrial safety systems. Over the past few decades, mechanical cup-type anemometers have been the…

Introduction In the field of industrial automation, silos, storage tanks, conveyor lines, packaging equipment, and water treatment systems all require precise control of one core piece of information: where is the material right now? Traditional liquid level meters or material…
