Hello,

I want to use strain gauges on the DT85 and CEM20 device. The strain gauges we will use have a quarter bridge. Does the DT85 device and the CEM20 device have a wheatstone bridge? Or will we use resistors ourselves to make the rest of the devices a full bridge?

Hi oacksz,

The logger does not have completion resistors to make a Wheatstone bridge for strain gauges. You must add external resistors; please use high-accuracy and low-temperature coefficient resistors.

If you aim to have a complete bridge, then three extra resistors are needed, but you can also aim to have a simulated bridge with only one resistor.

Best regards,
