Thunder proof for TML-NET NNZ-2A

The NNZ-2A is used for protecting TML-NET network measurement system from induced lightning. When the cable of instrument or network-module receives induced lightning, failure may be caused in the network driver and/or network module by the lightning surge. The NNZ-2A is connected to the connection cable of the network, and works to flow the surge current to the earth when induced lightning occurs. In addition, during standby of measurement, it automatically shuts off the network line to protect the network driver and network modules from the lightning surge.

• Specifications

  Type	NNZ-2A
  Surge tolerance	100A (8/20µs impulse)
  Available number for one system	NNZ-2A: up to 10 Low-comsumption network module: up to 100
  Rated power supply voltage	DC18 to 24V
  Standard used cable	Dedicated 2-conductor shielded cable Total extended distance: up to 2 km (at DC24V power supply voltage) up to 1 km (at DC18V power supply voltage)
  Display function	Drop of voltage in the network line  Over current of network module (Shuts off the network modules at over current)
  Environment	-20 to +60°C 85%RH or less (no condensation)
  Dimensions	50(W) x 28(H) x 100(D)mm (except projecting parts)
  Weight	Approx. 120g

DD series One-side strain gauge

These gauges are intended for measuring the bending and tensile strains separately by simply bonding the gauges on one side of a plate or beam. It works on the assumption that the strain distribution in the section of the specimen is linear along the height of the section when the section is subjected to both tensile and bending stress.  The gauges are effectively used for the measurement of a box　construction in structures such as bridges or pressure vessels, where the reverse side of the measurement object is not accessible for strain gauge installation. Optional (-F) lead-free solder specifications are also available.
