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, and the ND-100 is connected to a data logger for data transmission. Connection between the transducer and the ND-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.

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.

Leadwires dedicated to strain gauges

• Vinyl leadwires (standard length: 1m, 3m, 5m)

  Vinyl leadwires are widely used as strain gauge leadwires. They are available in various types and economical. Because the vinyl insulation can be colored, these wires allow color coding for each axis of rosette or multi-axial gauges. Each core is composed of stranded wires, making the leadwire flexible and easy to handle. The leadwire end can be easily processed for connection works.

  ・Small diameter vinyl wires (leadwire code LH, LHT)
  These leadwires feature very thin vinyl insulation and core wire, and are suited to wiring in tight spaces. Each core is composed of stranded wires to make the leadwire flexible and to minimize breakage due to repeated bending.

  ・Shielded vinyl wires (leadwire code LTSA, LTSB)These are 3-core wires with shield made of aluminium foil or braded copper wire. The outer sheath is made of vinyl. The shield has an effect on reducing influence of noise.

• Enamel leadwires (standard length: 0.3m, 0.5m, 1m)

  Enamel leadwires have a single core insulated with resin. Heat resistance and handling method vary depending on the type of resin. Because the mass and diameter of the wire are small, enamel leadwires are used for strain measurement in rotating specimens or measurement of multiple points located in close proximity.

  ·Polyurethane leadwire
  Polyurethane leadwires allow easy post processing because the resin can be removed with a soldering iron. Since the resin is not strong, it must be handled with special care.

  ·Polyester leadwire
  Polyester resin is harder than polyurethane resin. It cannot be removed with a soldering iron.

  ·Polyimide leadwire
  Polyimide resin is harder than polyester resin. It cannot be removed with a soldering iron.
