H3 nickel plated alloy steel S-type load cell

H3 nickel plated alloy steel S-type load cell

S-type load cells derive their name from their shape which, of course, is the shape of the letter “S”. The S type beam is normally used in tensions applications. They are primarily used for mechanical-to-electronic scale conversions and specific weighing applications like cranes, big bags etc. This model is providing wide range from 25 kg to 30 ton.

  • Nickel plated alloy steel IP67 “S” type load cell.
  • Tension and compression applications.
  • Also available in imperial capacities and dimensions.
  • Suitable for hanging, hopper and other weighing devices.
  • OIML approved.
  • NTEP Certificate no. 06-099A1
  • ATEX Optional

DESCRIPTION

The S Beam Load Cell is one of the most popular types of load cells. It was originally designed for in-line applications to convert mechanical scale to digital by replacing the spring or other in-line hardware. The S Beam Load Cell is available in variety of load ranges with both English & Metric threads. It is very popular due to its high precision, low price, and ease of installation. But since S Beam Load Cells are strictly designed for in-line applications they are very sensitive to extraneous load, torque, and moments. Off center loading must be avoided for the best performance & longer service life. Please refer to the pancake type load cell for applications requiring off center loading or extraneous load, moment and torque capabilities.
