Strain gauge type coding

Gauge Series		Compensation material (3)(4)		Lead wires preattached (4)
Code	Gauge type	Code	Material	Code
F	General purpose	3	Composite materials	002LE	2 cm, parallel, polyimide
WF	Waterproof construction	5	Composite materials	005LE	5 cm, parallel, polyimide
PF	Polyester foil gauge	8	Composite/glass materials	1L	1 m, parallel, vinyl, 2-wire
P	Polyester wire gauge	11	Mild steel (ferritic)	3L	3 m, parallel, vinyl, 2-wire
MF	Magnetic field use	17	Stainless steel (austenitic)	5L	5 m, parallel, vinyl, 2-wire
PM	Polyester mold gauge	23	Aluminium	3LT	3 m, parallel, vinyl, 3-wire
YF/Y	Post yield foil/wire gauge	50	Plastics (only for GF series)	5LT	5 m, parallel, vinyl, 3-wire
LF/L	Low elastic modulus	70	Plastics (only for GF series)
GF	For plastic material use	Self-temperature compensation (S-T-C) in ppm/K. Selectable for use on structural materials having a specific thermal expansion coefficient as listed above.		Indicates length and connection of lead wires.
BF	For composite material use
CF	Cryogenic-temperature use
QF/ZF	High-temperature use	(1) not always coded (2) not indicated for 120 ohms (3) indicated only for self-temperature compensated gauges, while the QF/ZF/AWn series without suffix code is temperature compensated only for mild steel between +10 to +100°C (4) applicable specification of compensation material and per-attached lead wire depends on gauge series
SF	Stress measurement
AW	Weldable capsulated gauge
BTM	Bolt stress measurement
FTP	Protected gauge
DD	One-side gauge
FAC	Crack detection
TF	Temperature measurement
KM	Concrete embedment use
