LY: Linear Strain Gauges with 1 Measuring Grid

Series LY is the first choice for strain measurements in only one direction. With types LY1, LY2, LY4, LY5, LY6, LY7 and LY8 we offer you linear strain gauges (SGs) in various geometries and sizes, each available with temperature responses adapted for steel, aluminum or to customer specification. Strain gauges are available with nominal (rated) resistances of 120, 350, 700 and 1000 ohms.

The measuring grid consists of constantan; the material of the measuring grid carrier is polyimide. While we offer a wide selection of products, they all have one thing in common: the excellent properties of HBM Y series strain gauges:

  • Universal strain gauge with excellent properties
  • Various connection configurations available, including version with practical connection cable
  • Flexible and easy to work with.

LY4 strain gauges also come with a connection cable!

The following temperature matching codes (1 … 9) apply to all types

1 = Ferritic steel (10.8 ppm/K; 6.0 ppm/°F)
3 = Aluminum (23 ppm/K; 12.8 ppm/°F)
5 = Austenitic steel (16 ppm/K, 8.9 ppm/°F)
6 = Silica/composite (0,5 ppm/K; 0.3 ppm/°F)
7 = Titanium and gray cast iron (9 ppm/K; 5.0 ppm/°F)
8 = Plastic (65 ppm/K; 36.1 ppm/°F)
9 = Molybdenum (5.4 ppm/K; 3.0 ppm/°F)

Remarks on Y Series

1) Strain gages are available in various temperature matches.
Insert the code in place of the placeholder “” to get the ordering number of the strain gage you need

2) Only available in matches for aluminum, ferritic and austenitic steel

3) Maximum permissible effective supply voltage (specified for steel)

4) Preferred types (available from stock) with the temperature matches specified in the column

5) With application aid (cut-to-size polyimide adhesive strip for easy positioning)
