Strain Gauge Pressure Sensor Principle
Strain Gauge Pressure Sensor Principle : When a closed container is subjected to the appilied pressure, it is strained (that is, its dimension changes). Measurement of this strain with a

Types of Load Cells
Load Cell A strain gauge – elastic member combination arrangement used for the measurement of load or weight is called load cell. It utilizes an elastic member as primary transducer
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
Basics of Pressure Measurement
A major portion of all industrial measurement relates in some way to pressure in its several forms. Flow, for example, is often measured by determining the pressure that exists at
Basics of Differential Pressure Transmitters
One of the most common, and most useful, pressure measuring instruments in industry is the differential pressure transmitter. This device senses the difference in pressure between two ports and outputs
Pressure Transmitter Manifolds
Pressure Transmitter Manifolds An important accessory to the DP transmitter is the valve manifold. This device incorporates manual valves to isolate and equalize pressure from the process to the transmitter,
Pressure Transmitter Vent fittings
Before removing a pressure transmitter from live service, the technician must “bleed” or “vent” accumulated fluid pressure to atmosphere in order to achieve a zero energy state prior to disconnecting
