To bond our strain gauges, please refer to the document of Bonding Procedure of BCM Strain Gauges.
You may also find this document in the documentation on each product page of strain gauges and adhesives.
Brief Introduction to Karma Strain Gauges
BCM SENSOR Karma strain gauge is a kind of metal foil strain gauge with the foil from Karma alloy. The main components of Karma alloy are copper, nickel, aluminum, and iron. This combination results in resistivity of 1.24~1.42 x 103Ω•m which is about three times higher than Constantan alloy, and has gauge factor of 1.86~1.98.
Advantages vs Disadvantages
Comparing with the Constantan strain gauges, the Karma strain gauges have the following advantages and disadvantages.
- Higher resistivity: about three times higher than constantan alloy;
- Higher operating temperature: up to 250°C;
- Capable of realizing E.M.C. (effective modulus compensation).
- It is more difficult to solder leads or wires onto solder pads of the Karma gauges.
Naked Solder Pads (SP) finishing vs Solder Dots (SD) finishing
The strain gauge with SP finishing is easier to be bonded. Therefore, if there is no difficulty in your application to solder leads onto the Karma gauges, the SP finishing is a good option.
As mentioned above, it is difficult to solder leads on solder pads of the Karma gauges. If you have no such experience, it is better to take use of the gauge with SD finishing although SD finishing makes the whole gauge less flexible and with less smooth than SP finishing.
Suggestion of Engineering Settings for Soldering Process
Before soldering the leads, you may use a sandpaper with 800 mesh to remove the oxide layer on the solder pads, and clean the solder pads with Ethanol.
To avoid the solder pads being oxidized again, it is better to solder the leads immediately after above-mentioned procedure of cleaning solder pads.
The suggested temperature set for the soldering iron is 300°C. Then solder the leads with the 2.5% flux and the solder, SD-705 or Sn60Pb40.
The above-mentioned engineering suggestions are based on BCM SENSOR experience. For more information, please contact us through Contact Form by choosing Technical Support.
The "Compare Product" function is aimed to bring you convenience to compare the different products which are interesting to you.
Once you click the "Compare Products" button on the webpage of the specific product, the key specifications of this product will be listed in a compare table on the "Compare Products" page.
You can review this compare table by clicking the "Compare Products" on the header.
The main difference is in the output signal.
The output signal of the transducers is same as sensors'. For the piezoresistive sensors and transducers, the output signal is in millivolt. The output signal of the transmitters is a conditioned and amplified signal, e.g., 4~20mA, 0~5Vdc, and I2C.
