DAOKAI 10 Pcs BF120-3AA 120ohm High Precision Pressure Resistance Foil Strain Gauge for Pressure Sensor, Load Cell with 20 Pcs Strain Gauge Terminal

About this item

• •Description:
• •Resistance: 120 ohms (resistance of the strain gauge refers to the resistance value measured by the strain gauge at room temperature, without installation and without force.)
• •Resistance to nominal tolerance: 120 ± 3 Ω
• •Resistance to average tolerance: ≤ 0.5Ω
• •Applicable temperature: normal temperature (-30 ° C -60 ° C)
• •Sensitivity coefficient and dispersion: 2.1±1%
• •Room temperature strain limit: 20000 um/m
• •Mechanical hysteresis: 1.2 um/m
• •Room temperature insulation resistance: 10000MΩ
• •Note:
• •1. In the strain gauge model, N* is the creep label, the label is different, and the creep value is different. The law is: (+)N9>N7>N5>N3>N1>N0>N8>N6>N4>N2>T0>T2>T4>T6>T8>T1>T3>T5(-) The actual creep value between adjacent labels differs by 0.01- 0.015% FS/30min
• •2. The resistance change of the strain gauge is very small, and there must be a proper circuit to detect the slight change. We usually choose a circuit in which the change of the strain gauge resistance can control the circuit, so that the output of the circuit can be similar to the resistance change. The electrical signal (voltage or current) can then be properly processed (amplified).
• •Package Included:
• •10 x BF120-3AA Strain Gauge
• •20 x Strain Gauge Terminal
