Lab equipement for loading and measurement

[Grunf]

Dear members,

I'm looking for laboratory equipment that will be used for loading and measuring during the dynamical testing of structures and soil.

I'd appreciate much any information regarding the web sites of manufacturers/ producers of such equipment and any information about (approximate) price of e.g.:

• bender element
  
• pore pressure transducers
  
• accelerometers
  
• strain gauges
  
• load cells
  
• displacement transducers
  
• other apparatuses/instruments needed to connect above-mentioned to a computer
  

Which manufacturer/producer of such equipment is fair in prices and provides good equipment?

I will be grateful for any help you can provide.

With regards,
Grunf
