KM strain transducers available in Australia and New Zealand from Bestech Australia
are designed to measure strain in concrete and synthetic resin while undergoing a transition from a compliant state to a hardened state.
Manufactured by TML, Japan, the KM series of strain transducers features extremely low modulus and waterproof construction, making them suitable for internal strain measurement during the early stages of curing.
Impervious to moisture absorption, KM strain transducers produce excellent stability for long-term strain measurement. This series also includes models that can measure actual temperature simultaneously with strain.
KM strain transducers are self-temperature compensated when performing a linear thermal expansion coefficient similar to concrete.
The rated outputs of KM strain transducers range from 2.5mV/V to 5mV/V, and non-linearity is 1% of the rated output. The capacity of KM series strain transducers is ±5000 x 10-6 strain.
