Trusted distributor of VPG and global brands
Wide range of load cells and sensors
Proven accuracy, durability, and reliable performance
The Load Cell 7 Wire is a specialized configuration designed to ensure greater accuracy, enhanced noise immunity, and stable signal transmission in weighing applications. While most load cells are available in 4-wire or 6-wire configurations, a 7-wire load cell includes an additional lead that serves as either shielding (drain wire) or an extra sense connection, making it ideal for environments where electrical noise, long cable runs, or temperature variations can affect weighing performance.
At Sensors and Gauges, we supply a wide range of load cells with advanced wiring configurations, helping industries achieve unmatched reliability in their measurement systems.
A 7-wire load cell is a strain gauge-based transducer where the cable has seven distinct conductors instead of the typical 4 or 6.
4 Wire β Excitation (+/-) & Signal (+/-)
6 Wire β Excitation (+/-), Signal (+/-), Sense (+/-)
7 Wire β Excitation (+/-), Signal (+/-), Sense (+/-), Extra (Shield or Ground)
This extra wire plays a crucial role in reducing signal noise, ensuring more accurate readings, and improving system stability β especially in industrial and outdoor weighing environments.
βοΈ Improved Noise Immunity β Extra shield reduces electrical interference βοΈ Stable Signal Transmission β Less drift over long cables βοΈ Higher Accuracy β Compensates for voltage drops and temperature changes βοΈ Reliable for Harsh Environments β Ideal for industrial and outdoor weighing βοΈ Flexible Integration β Works with advanced weighing indicators & controllers
