Strain Transducer

KM/KM-M Strain Transducer　±5000×10-6 strain

The KM series strain transducers are designed to measure strain in materials such as concrete, synthetic resin which undergo a transition from a compliant state to a hardened state. Their extremely low modulus (KM-M:25N/mm2) ,(others:40N/mm2) and waterproof construction are ideally suited for internal strain measurement during the very early stages of curing. They are totally impervious to moisture absorption, producing excellent stability for long-term strain measurement. Relative temperature measurement is also possible with the KM-B. The built-in thermocouple sensor of the KM-BT enable actual temperature measurement in addition to strain measurement. Adding to the above embedment use, surface strain measurement onto concrete, H-beam steel is also available with various optional fittings.
The new KM-M type small-diameter strain transducer has a smaller diameter than the conventional product and is suitable for measuring concrete with a thin cover thickness and surface strain. The KM series is compliant to CE marking except for KM-50F and KM-M.

Protection ratings : IP 67 equivalent for KM-30 / IP 68 equivalent for KM-50F to KM-100BT and KM-M

Coating Materials

Coating materials

The type of coating required and the application method differ depending on the environment in which the strain gauge is to be used. In general, if one type of coating is not sufficient, multiple coatings can be combined to protect the strain gauges. At TML, the coating applied directly to the surface of the strain gauge is referred to sequentiallyas the first coating, with subsequent coating layers referred to sequentially as the second coating, third coating, etc. Multi-layer coatings are recommended for strain gauge protection.
