Floating Vs. Grounded Voltage
In electrical circuits, voltage is always measured between two points: a point of high potential and a point of low or zero potential. The term “reference point” denotes the point…
Importance of Magnetic Flow Meters Grounding
Proper installation and grounding of magnetic flow meters is important for accurate, reliable, and measurement of volumetric flow rate.
Why we use Cable Shielding with Ferrites ?
Electromagnetic interference problems can arise anywhere since electromagnetic energy can unpredictably couple into systems, producing unwanted effects. Electromagnetic interference occurs when three elements come together: a source of interference a…
Basics of Total Organic Carbon (TOC) Analyzers
Carbon content is one of the most important parameters measured in various types of solutions, from commercial drinking water to industrial wastewater. Total organic carbon (TOC) analyzers are devices used to…
Input-Output Relationships of Transmitters
Have you ever had that actually forget something simple? And generally forgotten it was in the form like a formula. For example, the formula to convert temperature unit of degrees…
Catalytic Gas Detectors Principle
Catalytic gas detectors are based upon the principle that when gas oxidizes it produces heat, and the sensor converts the temperature change via a standard Wheatstone Bridge-type circuit to a…
Gas Detectors Installation Techniques
When considering the design of a combustible gas detection system, it is important to select the correct product for the purpose intended. It is likely that a combination of point…
Comparison of IEC & NEC Area Classifications
National Electric Code (NEC) Class I Any location in which flammable gases or vapors are or may be present in the air in sufficient quantities to produce an explosive or…
Standard Gas Detection Definitions
Volume CH4: The percentage by volume of combustible methane gas in an area. At 5% volume the mixture of methane is at 100% LEL and will explode if combined with…
Infrared Gas Detectors Working Principle
The Infrared (IR) detection method is based upon the absorption of infrared radiation at specific wavelengths as it passes through a volume of gas. Typically two infrared light sources and…
