Strain Transducer

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: 

• IP67 equivalent for KM-30
• IP68 equivalent for KM-100B to KM-100BT / KM-M
  
   

• Features
