Feature

●High precision, good stability and easy to use, suitable for 0.02-level sensors. (Output error is in the range of plus or minus 0.02 at full scale.)
●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.
●The resistance strain gauge can be used as a sensitive component and directly used for strain measurement of the tested part;
●It can also be used as a conversion element, and the sensor is constructed by an elastic element for indirect measurement of any other physical quantity that can be converted into strain of the elastic element.
●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.

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

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).

Note:
The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully!
Manual measurement, with small error. Please check size in detail before purchase.
Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.
