KFLB

Summary

The gage element is made of NiCr alloy, which exhibits excellent characteristics under low-temperature environments and is sandwiched between polyimde films. Thus, the KFLB series gages are suitable for strain measurement of tanks and vessels containing low-temperature liquids such as LNG and LPG.

Contents

Besides the silver-covered copper lead wire, KFLB strain gages with pre-attached lead cables are available on request.
When ordering, suffix the lead-wire cable code to the model number with a space in between.

E.g.
For the gage with a fluoroplastic-coated high/low-temperature 3-wire cable 5 m long pre-attached
