A strain gauge is a long length of conductor arranged in a zigzag pattern on a membrane.
When it is stretched, its resistance increases.
Strain gauges are mounted in the same direction as the strain and often in fours to form a full 'Wheatstone Bridge'.
The diagram above represents what might happen if a strip of metal were fitted with four gauges.
An downward bend stretches the gauges on the top and compresses those on the bottom.
A pressure transducer contains a diaphragm which is deformed by the pressure which can be measured by a strain gauged element.
All dimensions and specifications are nominal.
Due to our policy of on-going development, specifications may change without notice. Any modification may affect some or all of the specifications for our equipment.
