ElectroMechanical Level Measurement Working Principle
Electromechanical level Measurement Principle A sensing weight is let down on a measuring tape via a counter wheel. The tensile force of the weight is reduced as it hits the…
How Limit Switch Works ?
Presence Sensing is the act of detecting the presence or absence of an object with a contact or non-contact sensing device. The sensors then produce an electrical output signal that…
Microwave Barrier Level Switch Working Principle
Non-contact point level detection in bulk solids In many cases where contact methods are limited, microwave barriers are the appropriate solution. They avoid jamming, indicate point levels, solve positioning and…
DNP3 Communication Protocol Overview
The use of Open Standard communications for Supervisory Control and Data Acquisition (SCADA) is well established in an increasing number of utility and industry sectors across the globe. This has…
3 Port 2 Position Direct Acting Solenoid Valve Working Principle
The valve is 3/2 Direct Acting pressure balance design i.e. area at the Seat (Part-19) and balancing Plunger O Ring (Part- 80) are same, thereby air force acting on the…

Motor Inrush Current Measurements
Why inrush current important ? Inrush current, sometimes known as starting current or locked rotor current in motors, can be four to 10 times higher than a motor’s running current.…
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…
