KFLB Series
Low-temperature Foil Strain Gages

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
When ordering, suffix the lead-wire cable code to the model number with a space in between.
E.g.
KFLB-5-120-C1-11 with a fluoroplastic-coated high/low-temperature 3-wire cable 5 m
long pre-attached
→ KFLB-5-120-C1-11 F5M3
If no lead-wire cable code is suffixed, the gage is delivered with gage leads only.
(Silver-covered copper wires 25 mm long)
