Load cell

STS load cell sensor type IPS works by converting mechanical force, such as load, weight, tension, compression, or pressure, into digital values that can be read and recorded.

IPS load cells are central-hole type sensors designed to measure the tensile force of tendons, strands, and threaded rods, as well as the compressive force acting on sensors in building structures.

The IPS sensor is designed to show how much load is left in real time in post-tensioned strands on the structure. An anchor plate with wedges is placed on the hollow sensor, and through it the force is transmitted to the bearing plate and the structure itself.

Such sensors are supplied to Nuclear Power Plants with a warranty period of 100 years.

STS Type IPS

 

The STS IPS sensor makes it possible to determine the actual tensile force of a reinforcement beam, the force during testing, and also to monitor changes in the beam tensile force during the lifecycle of a structure.

Features of IPS
  • Measuring range — 3 to 15 mN.
  • Protection — IP55.
  • Height and diameter — 236 and 405 mm.
  • Weight — 115 kg.
  • Absolute force measurement error limits in the operating temperature range — +-300 kN.
  • Warranty — 100 years.
