Attaching Leadwires to Unbonded Strain Gauges
Ғылым және технология
It is generally considered that bonding strain gauges before attaching leadwires is technically superior, but in some instances pre-attached leadwires are essential. By learning this technique, customised leadwires can be added quickly and easily. This applies in situations where gauges must be installed but access with a soldering iron is not possible or allowed, such as restricted spaces, down-hole, on-site (to minimise time at site), heat sensitive materials or in explosion risk environments.
This short video shows the process from start to finish in real time. Our most common and class-leading CEA-series Advanced Sensors strain gauge and 330-DFV leadwire is demonstrated here, but the technique can be used across the majority of our extensive product range.

Great tutorial! Thank you for taking the time to upload!
How much temperature do you use for soldering?

Your solder pencil tip temperature varies based upon which solder you are using (361°F, 430°F, 450°F, 570°F, etc) and the heat sink of the substrate to which your strain gage is bonded. Most commonly for 361 solder on a great heat sink like aluminum, we teach in our workshops to have a solder pencil tip temperature of 650°F or so. This is dependent upon dwelling no more than one second so as not to thermally damage the strain gage nor the strain gage adhesive. This is also why high thermal capacity tips are used for strain gaging to transfer enough of that heat energy so as there is no need to dwell longer nor set the pencil tip temperature higher - which can cause damage from thermal shocking of the foil.
