●Parameters: Resistance: 350 ohm (Resistance of strain gauge refers to resistance values measured by strain gauge at room temperature, and it does not install or force. ); Resistance to Nominal Tolerance: 350 ± 0.1 Ω; Resistance to Average Tolerance: ≤ 0.5 Ω; Applicable Temperature: Room Temperature (-30 ~ 80 ℃)
●Material: Substrate: Denatured phenol. Grid wire: Constantan (copper alloy containing 40% nickel, 1.5% manganes), fully sealed structure, simultaneous temperature self-compensation and creep self-compensation
●【Size】Base size: 6.6 x 3.4mm / 0.26 x 0.13 inch Wire Grid Size: 3.0 x 2.44mm / 0.1" x 0.01", Lead Specs: 3-5cm long enamel wire
●Operating Principle: When measuring with a strain gauge, stick it to the surface of the product being tested. When the object is measured by force, the distortion gauge will also be deformed, and the resistance value will be changed accordingly, and the conversion circuit converts to changes in voltage or current to produce distortion measurements
●Package Contents: Package contains 10 BF350-3AA strain gauges and 20 strain gauge terminals

Description
Description:
Resistance: 350 Ohm (Strain gauge resistance refers to resistance measurements taken at room temperature without having to install a strain gauge. )
Resistance to Nominal Tolerance: 350 ± 0.1 Ω
Resistance to average tolerance: ≤0.5Ω
Applicable temperature: room temperature (-30°C - 80°C).
Sensitivity factor and variations: 2.0±1%
Room Temperature Distortion Limit: 20,000 um/m
Mechanical hysteresis: 1.2 um/m
Insulation Resistance: 10000 MΩ
Note:
1. For strain-gauge models, N* is a creep label, different labels and creep values are different. Legal is: (+)N9>N7>N5>N3>N1>N0>N8>N6>N4>N2>T0>T2>T4>T6>T8>T1>T3>T5(-) Actual crepe value between adjacent labels vary from 0.01 to 0.015% FS/30 minutes
2. Resistance change in the strain gauge is very small, and requires a proper circuit to detect minor changes. Typically, a change of resistance in the strain gauge selects a circuit that can control the circuit, so that the output of the circuit is similar to the resistance change. Then, electrical signals (voltage or current) can be properly handled (amplified)
