A Comprehensive Guide to Non-Contact Sensors and Their Applications
Sensors, both contact and non-contact, are crucial devices that allow the monitoring, detection, and reaction to conditions in an environment or within a process or piece of equipment. While myriad types of sensors exist and are designed to monitor varying conditions, all of them can be characterized as being one of two types — contact sensors and non-contact sensors. We’ll focus on the latter, diving into different technologies, types, and applications of non-contact sensor technology; but first, let’s explore what differentiates contact and non-contact sensors. Contact vs. Non-Contact Sensors: What’s the Difference? Measuring, monitoring, or detecting a particular condition [...]

How Capacitive Measurement Can Help Reduce Packaging Waste
Product packaging is often made of lightweight polymeric foams or plastic sheets and films. These materials are relatively inexpensive, but manufacturers still want to minimize waste and maximize yields. Across high volumes of low-cost materials, even a small per-unit savings can become significant, especially as the price of petroleum – a key ingredient in many polymers – continues to rise. For companies with environmental sustainability efforts, there are other important considerations as well. The excessive use of packaging materials can contribute to environmental pollution, especially with polymers that are slow to degrade. Yet, materials such as plastic sheets and [...]
Non-Contact Displacement Sensors for Detection and Measurement
Non-contact displacement sensors are designed to detect or measure physical properties such as linear displacement, thickness, proximity, and distance without physically touching the target. By emitting various forms of energy, such as capacitance, fiber optic, or laser triangulation, these sensors capture highly accurate readings without physically touching the object. This contrasts with traditional contact sensors, which rely on direct mechanical contact to gauge displacement or other physical properties. Benefits of Non-Contact vs. Contact Displacement Sensors Compared to contact sensors, non-contact displacement sensors offer faster response times, higher sampling rates, and minimal interference with the object being measured. They are [...]

Advantages of Measuring Semiconductor Thin Film Thickness with Capacitance
Thin Film Thickness Measurement Using Capacitance in the Semiconductor Industry In the semiconductor industry, the precise measurement of thin film thickness is crucial for ensuring the quality and functionality of wafer coatings. Thin films are deposited onto silicon and other wafer materials one atomic layer at a time, and the thickness of these coatings significantly impacts the wafer’s electrical, optical, and mechanical properties. Thin film thickness measurement is particularly important for semiconductor wafers, which may have either conductive metallic films or non-conductive metal oxide films deposited onto them. Common deposition methods include chemical vapor deposition (CVD) and physical vapor [...]
