Hi there I am hoping to attach a large number of strain gauges toa concrete surface, I need to know the compatibility with these strain gauges and a CR1000 series data logger

Asked by: Rodney99
Rodney, thank you for reaching out to us, the strain gauge will be bonded to the concrete and you will need to complete your bridge first. It appears the CR1000 IS A CAMPBELSCI Data logger, you may have to check with them, on whether it can complete a bridge and log full bridge circuits. If you have more questions please email

Are these strain gauges good for composite materials like carbon fiber? I would like to do some beam bending testing on a carbon fiber rod, but I'm not sure if these gauges are applicable to such an application.

Asked by: EthanL
Ethan, we have had customers use these strain gauges with composite materials in the past with success, please note that we do not however carry the adhesives that are compatible with composite materials.

Hi, id like to know what type of wire do you use to make the connection between the dataloggers and the strain gauges? Thank you.

Asked by: Vincent Dubé
Typically you use 4 conductor shielded cable to attach the strain gage bridges to the data logger. Description is as follows. 24 AWG Tinned Copper Wires , PVC Insulation, Aluminum-Polyester Shield with #24 Drain Wire, PVC Jacket Overall.
