The temperature will make the strain signals (resistance) of the four strain gauge change in the same direction and degree. Because two positive strains and two negative strains ar

Two or four strain gauge are pasted on the cylinder wall, one half of which is pasted on the solid part as the temperature compensation gauge, and the other half is used as the mea

The measured force causes corresponding displacement of elastic bodies (such as springs, beams, corrugated pipes, diaphragms, etc.), and the force signal is obtained through displa

A voltage converter is a rectifier circuit that converts alternating current in the power grid into direct current, and then converts a three-phase bridge inverter circuit into adj

In industrial control and many sensor application circuits, when simulating signal output, it is generally output in voltage. When transmitting analog signals over long distances t

The transmission wire itself has resistance, and the voltage signal generates a voltage drop on the wire, which means there is an error between the input signal of the amplifier an

If the input signal is a voltage source. And it needs to be transmitted to a distant load. The load current depends on the series resistance between the input signal and the load.

General requirements: Sensors or systems composed of sensors and secondary instruments should be equipped with user manuals, input and output wiring diagrams, and concise.

In the verification work of load sensors, it is common to experience strong temperature changes, external additional loads, and environmental changes during use, resulting in unsta

Sensitivity: 100-1000kg 1mV/V; 1.5mV/V above 1000kg; Non linearity: ± 0.5% RO

The instruments and equipment used for in-situ calibration mainly include DC stabilized power supply, DC amplifier (KWS3020B), standard weight (F2 level), etc. Computer data collec

The load on the load sensor (the force acting on the sensor) must be applied as much as possible in the measurement direction. Torque and bending moment, eccentricity and lateral l
