What Are the Different Types of Force Dynamometer?

Dynamometer A portable measuring instrument used to measure various force values or loads. Also called dynamometer. There are various classifications, which are divided into working dynamometer and standard dynamometer according to the object. The main indicators for evaluating the accuracy level of the dynamometer are repeatability R and stability Sb. R reflects the change of the data obtained by adding (unloading) multiple times during a complete test; Sb reflects the difference between the test data and the previous data after a period of time. ^[1]

Standard dynamometers for static weight, lever, hydraulic, and superimposed dynamometers are mostly force sensor types, and their accuracy is divided into three levels of 0.01, 0.03 and 0.05. Various types of force sensors are equipped with appropriate electric measuring instruments to form a sensor type force gauge or an electronic force gauge. Standard dynamometers are still mainly resistance strain sensors with a wide range, high accuracy and strong adaptability. Standard dynamometers used for the verification or calibration of various materials testing machines are mostly dial gauges, and their accuracy is divided into three levels of 0.03, 0.05 and 0.1. ^[1]

Classification

Divided into digital dynamometer and mechanical dynamometer

Dynamometer introduction:

The dynamometer, also called dynamometer, is divided into two types: digital dynamometer and mechanical dynamometer (pointer type).

Digital dynamometer

The large display can accurately measure the maximum amount of information obtained; the current value, maximum value, minimum value, etc. At the same time, a progress bar can be used to indicate whether the test force is close to the maximum range. If necessary, the backlight can be used to make readings more convenient and comfortable.

Digital Force Gauge

Force Gauge Point Force Gauge

Featuring a large 2.25-inch dial, for enhanced resolution and readability, the peak hold button has an ergonomic shape and. Improved 5% full scale accuracy.

Mechanical dynamometer

Use of dynamometer

When using the digital display dynamometer, pay attention to check whether the battery voltage is normal, and charge it in time to avoid deviation. When selecting the range, it is the same as the pointer type. Selecting the appropriate one will cause damage to the dynamometer sensor. Charge the dynamometer regularly if not in use for a long time. At the same time, when the weather is humid in summer, you should pay attention to the storage environment of the instrument to prevent the instrument from rusting.

Electronic dynamometer

Use of dynamometer

The dynamometer has a wide range of applications and can measure tension and pressure.

Electrical: wire end test, switch force test, screw torque test, peel test, circuit breaker test, wrench force test, contact switch test, etc.

Packaging: peeling force, cap opening, cap torque test, capping machine control test, film hole, load test, etc.

Automotive industry: operating force test, assembly force test, shock absorption test, screw torque, etc.

Food processing: fruit hardness, sticking strength, bottle opening force, peeling force, vertical pressure, quality inspection

Medical: Force measurement in physical therapy, prosthetic correction, syringe test, suture test, stroke test
