DY应变片有两个平行排列的测量栅丝。这些应变片(SG)的典型应用包括弯曲梁的测量

DY1 和 DY4应变片提供各种几何形状和尺寸的应变片(SG),每种应变片的温度响应都适合以下材料:

  • 铁素体钢(10.8 ppm/K; 6.0 ppm/°F);温度匹配代码:1
  • (23 ppm/K; 12.8 ppm/°F);温度匹配代码:3
  • 奥氏体钢(16 ppm/K,8.9 ppm/°F);温度匹配代码:5
  • 石英玻璃/复合材料(0.5 ppm/K; 0.3 ppm/°F);温度匹配代码:6
  • 钛和灰铸铁(9 ppm/K; 5.0 ppm/°F);温度匹配代码:7
  • 塑料(65 ppm/K; 36.1 ppm/°F);温度匹配代码:8

在占位符“x”处插入温度匹配代码,以获取所需应变片的订购号。标有#符号的应变片仅适用于铝、铁素体和奥氏体钢

350欧姆应变片测量栅丝由康铜制成,基底为聚酰亚胺。优选应变片的快速交货 — 现货供应!

Simplified Documentation and Parameterization

To optimize the measuring point documentation each strain gauge includes two stickers which can be placed next to the measuring point and near the measuring amplifier. Benefit from the parameter information directly in the measurement setup:

  • QR code that directly links to the data sheet of the respective strain gauge
  • The product and production batch numbers
  • The k-factor and a additional space for your notes
  • QR code containing the values of the individual strain gauge to simplify computer-aided parameterization or documentation with a scanner

Please note: newly produced strain gauges all come with the sticker in stock, strain gauges still in stock do not have this feature yet.
