PMF series Mold strain gauge
PMF series mold strain gauges are small gauges that are embedded in concrete or mortar for use in such applications as loading tests. They can also be embedded in smaller test subjects. The gauges employ super engineering plastics in their backing material, which provides water resistance. Our temperature-integrated model allows measurement of both strain and temperature. In addition to standard lead wire lengths, we can make lead wires to any length (made-to-order).
* Strain Transducer KM is suited to long-term use.
