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 [...]
Enclosure Ratings
Enclosure Ratings When it comes to an enclosure rating a good standard rating system needs to be utilized to define the types of environments in which certain kinds of enclosures cane be used (such as electrical). A rating system also identifies whether a fixed enclosure can stand up to certain environmental conditions. Users as well as manufacturers benefit when quality standards are in place. Overall communication, economics, and safety are improved between the seller and the buyer. Below we will be looking at the National Electrical Manufacturers Association’s (NEMA) rating scale for enclosures. NEMA defines the standards used in [...]
What is Calibration, and Why Is It Important?
Calibration Calibration in measurement technology is the evaluation of measurement values that is delivered by a device that can deliver a calibration standard of known accuracy. Think of this standard as another measurement device of known accuracy. This device would generate the quantity that would be measured, such as voltage. The outcome of the comparison can result in three possible outcomes: no significant error is noted on the device that is being tested, a significant error was noted but no adjustments were made, or an adjustment was made to correct the error to an acceptable level. BIPM The International [...]
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 [...]
