Displacement Measurement
Types of Displacement Measurement Run-Out/Vibration There are many ways to measure run-out/vibration including the type of measurement system, run-out or vibration (direction), and environment where the system is being installed. Choosing the wrong kind of equipment can lead to drastic consequences. You can run into issues such as increased man-hours during production and issues with insufficient precision. Example Applications Run-out measurement of HDD surface Laser displacement sensors are very helpful in measuring the oscillation at a single point on a specific target’s exterior. The further away that vibration amplitude is from the center of rotation from a target, [...]
Measurement List
Measurement List Displacement sensors/measurement systems make many different types of measurements possible. Typically the application environment and the measurement target determines the type of measurement method that should be used for optimum results. There are several types of measurement systems that you should become familiar with: Dimension Measurement Thickness Width Height/Step Outer Diameter Angle Radius / Inner Diameter Displacement Measurement Run-out/Vibration Eccentricity Stroke Positioning Edge Position Gap/Clearance Profile Measurement Warpage and Flatness 2D Shape 3D Shape Thickness For those searching for Thickness Measurement Systems If you’re searching for the best method of measuring thickness, the process may not be [...]
Inline/Offline Measurement
Inline and Offline Measurement: Key Differences and Applications Inline and offline measurements are two distinct types of measurements used in manufacturing and production. Inline measurements are typically automatic and integrated directly into the production process, while offline measurements are manual, often conducted after production. Understanding the differences between these two types of measurement is crucial for optimizing production workflows and ensuring high-quality standards. Inline Measurement Inline measurement refers to the real-time monitoring and inspection of products as they move through the production line. Sensors or instruments are embedded directly into the manufacturing process, automatically collecting data on dimensions, [...]
Fiber Optic Sensors
Fiber Optic Sensors MTI Instruments provides high-performance fiber optic sensors and probes engineered for applications requiring large measurement ranges and extended standoff distances. These non-contact, modular sensor systems feature interchangeable probes and dual-channel capability, allowing for simultaneous measurements of displacement, position, or vibration at two points. Designed for precision and flexibility, they excel as fiber optic position sensors, motion sensors, and optical displacement sensors in environments where conventional technologies are limited by physical contact or EMI interference. Our advanced fiber optic probes automatically compensate for significant variations in surface reflectivity, enabling accurate monitoring across a dynamic reflectance [...]

Important Terminology for Measurement System Selection
Important Terminology for Measurement System Selection Mounting conditions / Mounting mode – to properly measure an object/target with the aid of a laser displacement sensor, you must reflect the light from the object to the receiver. Measurement systems that use a triangulation method for measurement, along with variable surface conditions of the object, have sensor heads that are installed at an angle so that light can be reflected and received in the proper manner. Opaque targets – both the sensor head and the target must be installed parallel to each other so that a portion of light hit the [...]
History of Measurements
The History of Measurements Measurement, loosely defined is the length, amount, or size of something that is measured. Long ago, the idea of a universal measuring system didn’t exist. That was, until the 18th century where measurement became a cohesive system. Before this period, countries such as France had measuring systems for nearly every profession. In 1795 the number of measurements in France alone numbered well over seven hundred. The names for many units of measurement were borrowed from human morphology. For example, the foot, the hand, the pace, etc. Still, however, these units of measurement were not standardized. [...]
Electronic & RF / Radio Frequency Noise
What is RF Noise? RF noise (radio frequency noise) is unwanted electromagnetic interference that appears across the frequency spectrum in electronic systems. Understanding what is rf noise is crucial for anyone working with electronic equipment, as it directly affects system performance and signal quality. Radio frequency sound and noise frequency characteristics vary significantly depending on the source and application. RF noise manifests as random fluctuations that can mask desired signals, cause data errors, and limit overall system capabilities. Understanding Noise Frequency Characteristics Frequency Noise Types and Their Spectrum Noise frequencies are categorized based on their frequency distribution patterns: White [...]
Capacitor Characteristics
Capacitor Characteristics Capacitors are often defined by their many characteristics. These characteristics ultimately determine a capacitors specific application, temperature, capacitance range, and voltage rating. The sheer number of capacitor characteristics are bewildering. Furthermore, it can be very difficult to interpret and understand the information printed onto the body of a capacitor. Capacitors come in various types or families, and each of these groups has their own identification system and characteristics. Some of these systems are easy to interpret. However, other systems are inundated with symbols, letters, and colors that can be confusing to comprehend. Identifying a capacitor's characteristics typically [...]
