# MEGE 应变仪培训设备

## 創新系統

The Strain Gauge Training Unit, "MEGE", designed by EDIBON, studies the strain gauges and their application in the measurement of strain.

## 一般說明

The Strain Gauge Training Unit, "MEGE", provides an introduction to the fundamentals of measurement with strain gauges, to compare how resistance strain gauges work and how they measure strains in different structures (torsion, tension and bending systems).

The unit consists of a frame, which allows to place several measuring specimens quickly and precisely.

Three test specimens (bars) for torsion, tension and bending are each fitted with four strain gauge measuring points. The bars are loaded incrementally, allowing for the strain reading to be monitored.

The strain gauges are inside a transparent cover that protects them and make them clearly visible for the visualization of the process.

The unit includes a set of weights, two weight holders to give each specimen (bar) a range of stress, and a console with an amplifier and a digital display to show all readings.

Three additional tension bars are available as accessories, made of aluminum, copper and brass, to determine the elasticity modulus (Poisson's ratio and Young's modulus) in the exercises.
