Gauge Protector

Gauge protector

This rubber protector is designed to protect gauges which are bonded onto metal surface from the environment for long-term measurement. The strain gauge is packed inside together with the applied adhesive and overcoating materials. The protector is also provided with a hole for cable intake. It allows the entire area to be isolated from ambient conditions which may affect reliable measurement, and further increases the coating performance.

After completing the 1st and 2nd overcoating layers, epoxy resin is injected to provide mechanical protection.

Strain Transducer

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

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.
