High Endurance Strain Gauge

DSF series High Endurance Strain Gauge

These gauges are designed for fatigue tests, and can reach a fatigue life of over 10 million times at a strain level of ±3000 με. Compared to previously (1 million times at ±1500με), these are gauges of exceptionally high durability.
In aviation and other areas, repeated load tests of large elongation of composite materials are conducted. However, it had been necessary to adhere a new strain gauge frequently as a gauge reached its fatigue life. The DSF series greatly reduces time and cost of adhering gauges.

High Endurance Strain Gauge
Applicable specimen Metal, Composite materials
Operational temperature(°C) -60 to +200°C
Temperature compensation range(°C) -
Applicable adhesive CN, EB-2B, C-1
Backing Polyimide
Element Special alloy
Strain limit 1% (10000×10-6 strain)
Fatigue life at room temperature 1×107 (±3000×10-6 strain)

* Because this strain gauge is not self-temperature-compensated, it is recommended to preliminarily measure thermal output of this strain gauge using a dummy specimen which is made of the same material as the test specimen.

Magnetic field strain gauge

MF series Magnetic field strain gauge

These non-inductive strain gauges are designed for strain measurement in magnetic fields. Two strain gauge elements are overlapped to cancel out electromagnetic induced noise occurring in the gauge, and the twisted lead wire also similarly works to cancel out induced noise. Their structure makes them less sensitive to induced noise from alternating fields.

Applicable specimen Metal, Concrete
Operational temperature(℃) MFLA:-20 to +80℃
Temperature compensation range(℃) -
Applicable adhesive CN, CN-E, RP-2
Backing MFLA:Special plastic
Element Ni-Cr
Strain limit 1% (10000 x 10-6 strain)
Fatigue life at room temperature 1 x 106 (±1500 x 10-6 strain)

TML-NET Compatible Transducers

TML-NET Compatible Transducers

This is a strain gauge based transducer with a built-in network module. It is connected to a network driver ND-100/NDR-100, and the ND-100/NDR-100 is connected to a data logger for data transmission. Connection between the transducer and the ND-100/NDR-100 is available using an exclusive two-core cable since the data transmission is made in degital form. Additional TML-NET compatible transducers can be cascaded using the two-core cable.

Features
  • Built-in digital conversion module for TML-NET
  • Not influenced by lowering of insulation resistance and no sensitivity decrease
  • Easy wiring
  • Insulation check feature

Low elastic strain gauge

GF series Low elastic strain gauge

These strain gauges are suited for the measurement on materials such as plastics, which have low elastic modulus compared to metals. The specially designed grid pattern reduces the stiffening effect of strain gauge on the specimen. This series is available with self-temperature-compensation for materials having coefficient of thermal expansion of 50 or 70 ×10-6 strain/℃.
New series of strain gauges named GOBLET are added to this series.  They are compliant with RoHS 2 Directive 2011/65/EU and supplied with CE marking.  Even though lead-free solder is used in the GOBLET gauges, they show better performance than conventional strain gauges owing to the adoption of unique gauge pattern.  Extension leadwires with CE marking are also available.
