BF series Composite strain gauge Composite Strain Gauge

BF series Composite strain gauge

BF series composite strain gauges are developed for measurement on composite materials, and are designed with a proprietary special grid pattern to reduce the stiffening effect of the strain gauges. Models are available for materials with coefficients of thermal expansion of 3 × 10-6/℃, 5 × 10-6/℃、8 × 10-6/℃ allowing use with ceramics, carbon, composite materials, etc. 
A new series of strain gauges bearing the CE mark, GOBLET, has been added. This CE-compliant series of products is compliant with RoHS directives. These gauges exceed the capabilities of conventional strain gauges with lead-free soldering as well as a unique tab design. CE-compliant extension lead wires are also available.

Slip-ring Type Slip-ring type SLW-NC 6-Component Wheel Force Transducer

Slip-ring type SLW-NC 6-Component Wheel Force Transducer

This is a load cell which measures an external force passed to the tire from the road surface while the car is running, by breaking the force down into orthogonal three-component force and three moments around the force axes. Highly precise measurement is possible in every driving condition owing to its load detecting part with reasonably arranged strain gauges, slip ring and rotary encoder assembly with improved vibration resistance, and waterproof structure. This transducer is used together with the exclusive 6-component force analyzer MF-660. The 6-component force is indicated in a coordinate system based on the car body.

Slip-ring type SLW-NC 6-Component Wheel Force Transducer
Features
  • High precision
  • Light weight
  • Installation possible to various vehicles using exclusive rim and hub adaptor
  • Easy installation to an actual car
  • Running in the rain possible by the waterproof structure

Strain Gauge Clamping Jig PRESSEE PM-19

PRESSING JIG - PRESSEE PM-19

When adhering a strain gauge to a specimen, it is necessary to press the strain gauge until the adhesive hardens.　PRESSEE not only applies pressure (PRESS) on the strain gauge, but is also a pressing jig allowing a strain gauge to be checked visually (SEE) from the clear pressing portion. Using PRESSEE saves time in having to keep pressing with the fingers, and a constant pressure on a strain gauge allows stable adhesion quality. The position of the strain gauge, flow of the adhesive, and other aspects can also be checked visually while pressure is applied.

PRESSEE
Features
  • Magnetic method stabilizes the pressing force and adhesion quality
  • As the pressing part is clear, you can check the bonding status with your eyes
  • Spring mechanism enables easy attachment and removal with weak force
  • Work efficiency is improved because other work can be carried out during pressing

  • Specifications
    Type PM-19 (PRESSEE)
    Applicable gauge Gauge length 6 mm or less (backing within ø15 mm)
    Pressing method Magnetic method by permanent magnet
    Object to be bonded Flat surface of magnetic body (such as steel plate with thickness of 1mm or more)
    Shape of pressing surface Φ19 mm (adhesive clear cushion material)
    Release film Polyethylene sheet (suplied to the strain gauge or optional)
    Operating temperature range +5 to +50℃ (within curing temperature of used adhesive)
    External dimensions Φ29xApprox. 30 mm *
    Weight Approx. 30 g

    * It shrinks by pressure because of spring mechanism.

UBF series Composite strain gauge Composite Strain Gauge

UBF series Composite strain gauge CE

These are strain gauges developed for measurement on composite materials, and are designed with a proprietary special grid pattern to reduce the stiffening effect of the strain gauges. Owing to the development of gauge backing with better compliance, the number of repetitions in thermal cycling tests and creep characteristics have been significantly improved compared to conventional strain gauges (Tokyo Measuring Instruments Laboratory comparison). Optional (-F) lead-free solder specifications are also available.

High Temperature Use Strain Gauge QF series

QF series strain gauges for high temperature use

These are foil strain gauges having a polyimide resin backing.  Strain measurement in high temperature is easily performed by bonding the strain gauge with room temperature curing adhesive NP-50B.  Strain gauges for stress concentration measurement or torque measurement are also available in addition to general use gauges in this series. 
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.
