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

- ?【Parameter】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)
- ?【Material】Substrate: modified phenolic; grid wire: Constantan (copper alloy containing 40% nickel, 1.5% manganese), fully enclosed structure, simultaneous temperature self-compensation and creep self-compensation.
- ?【Size】Base size: 6.6 x 3.4mm / 0.26 x 0.13inch; Wire grid size: 3.0 x 2.44mm / 0.1 x 0.01inch, Lead specification: 3-5 cm long enameled wire.
- ?【Working Principle】When measuring with a strain gauge, attach it to the surface of the object to be tested. When the measured object is deformed by force, the sensitive grid of the strain gauge is also deformed, and the resistance value changes correspondingly, and is converted into a voltage or current change by the conversion circuit, thereby realizing the strain measurement.
- ?【Package Content】The package comes with 10 x BF120-3AA Strain Gauge, 20 x Strain Gauge Terminal
