Introduction to the Functions and Features of the External Force Gauge Push Pull

The external sensor force gauge push-pull is a small and simple test instrument for pushing and pulling force. It has the advantages of high precision, easy operation, and portability. It also has a peak switching operation knob, which can be used for peak load indication and continuous load value indication.

The digital push-pull gauge is suitable for push-pull load testing of electronic appliances, light industrial textiles, construction hardware, lighters, and ignition devices, fire fighting equipment, pen making, lock making, fishing gear, and power machinery, scientific research institutions, and other industries.

1. Function introduction of external sensor force gauge push-pull

The force gauge push-pull has a large LCD screen with clear display and easy reading. The metal housing of the force gauge push pull provides adequate protection for the sensor and circuitry. At the same time of measurement, the display screen of the force gauge push pull will display the pulling force or the pushing force respectively.

The battery power of the pull-push meter will be displayed, and an alarm signal will be issued when the force gauge push pull is overloaded. Users can choose the appropriate model and load range according to the application.

Equipped with a complete set of accessories including: force gauge push pull, hard plastic housing, five commonly used measuring probes, built-in battery and AC power supply. User-programmable upper and lower limits are measured notification functions.

2. The characteristics of the external sensor force gauge push pull

1) Repeatability: Repeatability refers to the degree of inconsistency in the characteristic curve obtained when the input quantity of the sensor force gauge push pull is continuously changed many times in the same direction over the full range.

2) Sensitivity: Sensitivity is an important indicator of the static characteristics of the digital push-pull force gauge. It is defined as the ratio of the increment of the output quantity to the corresponding increment of the input quantity that caused the increment. Use s to represent the sensitivity of the push-pull gauge.

3) Linearity: refers to the degree that the actual relationship curve between the output of the sensor force gauge push pull and the input deviates from the fitted straight line. It is defined as the ratio of the deviation between the actual characteristic curve and the fitted straight line of the force gauge push pull in the full-scale range to the full-scale output value.

4) Drift: The drift of the sensor force gauge push pull means that the output of the sensor force gauge push pull changes with time under the condition of constant input. This phenomenon is called drift.

There are two reasons for the drift of the force gauge push pull: one is the structural parameters of the sensor itself; the other is the surrounding environment of the force gauge push pull.

5) Hysteresis: The phenomenon that the input and output characteristic curves of the sensor do not overlap during the change of the input quantity from small to large (positive stroke) and the input quantity from large to small (reverse stroke) is called hysteresis.

For input signals of the same size, the positive and negative stroke output signals of the sensor force gauge push pull are not equal in size, and this difference is called the hysteresis difference.
