| Y: Yielding type. For measurement of large strains ranging to plastic sphere. Designed not to cause stress concentration at the point where leads are soldered. | ||||
| C: For crack analysis. Gauge grids are arranged in parallel. Gauge resistance increases in the form of stairs when a crack takes place somewhere within the grids. | ||||
| X: For crack propagation detection. With the lengthy grid of this gauge, cracks propagating extensively can be sensed. | ||||
| P: For application to internal surface of pipes or threaded holes where gauges are difficult to install. The test object is perforated for installation of this gauge inside. Note, however, that application is considerably critical as the gauge is likely to be damaged when installed or its performance is affected by air bubbles introduced during installation. | ||||
| W: Waterproof-Molded Type Strain Gauge. Vinyl cable (2 parallel wires of 1 mm. in external diameter, respectively) is being connected with strain gauge and the gauge is molded with special Epoxy resins. No special protection for waterproofing is necessary after its having been installed on the test object. The feature can be applied to all versions in Nxx-FA Series of gauge length from 2mm. to 10mm., except N34, N35 and N51. | ||||
