KHC High Temperature Encapsulated Weldable Strain Gauge

Measurement Environment: Dynamic 550ºC, Static 500ºC
Applications: Uniaxial, 2-element Temperature compensdated

KYOWA encapsulated weldable strain gauges are hermetically sealed. They consist of a sensing part and a cable to transmit output signals from the sensing part. The sensing part is composed of a metal tube and a flange. The highly heat resistant metal tube has strain-gauge element(s) and insulation material sealed in. The flange is spot-welded to the measuring point. The cable is a mineral-insulated metal sheathed cable (Ml cable) filled with heat-resistant insulating powder in which the leadwires are embedded.

This structure enables these strain gauges to measure strain under harsh environments affected by high temperature, high pressure or high humidity. High-temperature models can be applied to strain measurement in fields including nuclear/thermal power generation, automobiles and aircraft. The normal-temperature model features waterproof construction and long-term stability, and thus is suitable for outdoor strain measurement in the automobile, civil engineering, architectural and many other fields.
