[[epsilon].sub.2] = -v([[epsilon].sub.1] + [[epsilon].sub.1]) represent the unit strain indicated by the transducer no.
[[epsilon].sub.4] = -v([[epsilon].sub.3] + [[epsilon].sub.3]) = -v([[epsilon].sub.1]-[[epsilon].sub.2]) represent the unit strain indicated by the transducer no.
Developed in the 1930s, these gauges can measure the unit strain at a specific board location.
The unit strains molecules too large to pass through it, blocking most contaminants.
