Your Name (required) Your Email (required) Feedbacks +971 4 2261890; sales@antdubai.com; 0. My load cells have 4 wires and the load combinator has only 3 inputs for the "load sensors" that a "Typical bathroom scale" uses. If you open up an electronic bathroom scale, you’ll find a large rat's nest of wires. Use a multimeter to measure the resistance between the three wires. A PCB to combine four individual strain gauges or load sensors into the standard wheat bridge configuration and 4-color wiring found on load cells. The Load Sensor Combinator was created to combine the 12 wires found in a bathroom scale into the standard four-wire Wheatstone bridge configuration. Availability: 22 in stock (can be backordered). I'm interested in understanding how the wheatstone configuration was implemented in this board. Thank you for swift, trouble free delivery. This allows the user to gather the temperature of the scale in case there is a large variance between the scale and the amplifier. The SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration. Please help! If your amplifier and supporting electronics are more than a few inches away from the scale, an RJ45 footprint is provided. Please use the link in the banner above, to get started with posting a topic in our forums. You may have noticed that the HX711 library isn't in our Github repository. These three pins are accessed through the RJ45 connection as well, allowing remote temperature readings to be gathered over one twisted pair Ethernet cable. can this combinator combine for load cells (cells with 5 cables like tas606)?? This allows the amplifier board to be placed many feet away from the scale itself. SparkFun Load Sensor Combinator, The SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration . Is it possible to connect them with this combinator and using only one amplifier? $59.95. The four Wheatstone pins (E+/E-/S+/S-) as well as the shield pin are connected to twisted pairs within a standard cheap Ethernet cable. 2 years ago by Member # 1403595 verified purchaser supporting electronics are more than few.
