How to Stop Cyber Attacks on PLC or DCS?
As control system professionals, it is in our interest to ensure our measurement and control systems are secure from unauthorized access. It is helpful to regard system security similarly to…
Unbonded Strain Gauge Principle
These strain gauges are not directly bonded onto the surface of the structure under study. Hence they are termed as unbounded strain gauges. Description of the Unbonded Strain gauges: The arrangement of an unbonded strain gauges…
Semi Conductor or Piezo Resistive Strain Gauge Principle
These gauges are directly bonded (that is pasted) on the surface of the structure under study. Hence they are termed as bonded strain gauges. The three types of bonded strain…
Metal Foil Strain Gauge Principle
These gauges are directly bonded (that is pasted) on the surface of the structure under study. Hence they are termed as bonded strain gauges. The three types of bonded strain…
Fine Wire Strain Gauge Principle
These gauges are directly bonded (that is pasted) on the surface of the structure under study. Hence they are termed as bonded strain gauges. The three types of bonded strain…
Sling Psychrometer Principle
Sling Psychrometer is used to measure both the dry bulb and wet bulb temperatures at time. These temperatures are a measure of humidity content in air. Description of Sling Psychrometer…
Humidity Sensing Absorption Hydrometer Principle
A change in resistance with change in humidity is taken as a measure of humidity. This is type of Electrical Humidity sensing Absorption Hydrometer, know more about mechanical humidity sensing…
Hair Hydrometer Principle
Due to humidity, several materials experience a change in physical, chemical and electrical properties. This property is used in transducer that are designed and calibrated to read relative humidity directly. Hair…
Dew Point Meter Principle
Dew Point Meter Principle By Cooling at constant pressure if the temperature of air is reduced, the water-vapour in the air will start to condense at a particular temperature. This…
