1. Straightness The degree to which the practical connection curve between the sensor output (voltage) and the input (torque) deviates from the ideal straight line. General requirements: ≤ ±2%. 2. Hysteresis The difference in voltage between all test positions during the test stroke. General Requirements: ...
The load cell in the industry will be more understood, our load cell manufacturers or take a look at the elements of our force measurement stability, there are many factors that affect the stability of the load cell, which can be summarized as follows: 1. The structure of the load cell Load Cells ...
The selection of load cells mainly includes the following four aspects, namely, the sensitivity of the sensor, the accuracy of the sensor, the stability of the sensor, and the number and range of the sensor. 1. Sensitivity Usually, in the ...
The FS101 sensor with alphanumeric display continues the operation and commissioning of Turck's FS+ fluid sensor series, which Turck has added to its FS+ fluid sensor series. The new FS+ sensor has the same look and feel, with the same look and feel as all its ...
The first is pressure, and the transmitter can't afford to lose it. In this case, look at the pressure connector to see if it is leaking or clogged, if you admit that it is not, look at the wiring and see if the power supply is normal, simple pressure to determine if the output has changed, or if there is an output at the zero point of the sensor ...
Pressure sensors are used in all walks of life, especially in the industry, which uses a lot of pressure sensors, but the industry generally requires that the pressure sensor can be anti-corrosion, and the pressure sensor joint and cavity are made of imported stainless steel.
A linear displacement sensor is an electrical signal device that converts the linear mechanical displacement into a linear or arbitrary function relationship through the potentiometer element. In order to achieve the intention of measuring displacement, it is necessary to have a confirmation relationship between the change in displacement and the change in resistance. Usually...
Sensitive components Load cell: A component that directly senses the measured (mass) and outputs other quantities that are definitely related to the measured amount. For example, the elastomer of the resistance strain gauge load cell is to transform the mass of the measured object into deformation; The elastomer of the capacitive load cell will be tested ...
A tensile pressure sensor is a device that converts a physical signal into a measurable electrical signal output. Precautions for Nala pressure sensors: 1. The appearance of the equipment should be as flat as possible, without oil or film, and the equipment should have sufficient strength and rigidity, ...
As the main force measurement sensor, the force measurement scale of strain resistance sensors varies from muscle fibers to moon rockets, and the accuracy can reach 0.01%-0.1%. There are tensile types (in, tube, ring), zigzag and shear. Features of strain sensors: ...
Pressure sensors have been widely used in recent years, many products are in use, according to different types of test pressure, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors, what are the strain characteristics of pressure sensors? ...
Sensors are used in almost every profession in modern times, and these occupations can record according to the signals sent by the sensors, so how do they distinguish the authenticity of the output signals of the sensors? 1. Distinguish from the void voltage ...
LVDT displacement sensor has a very high measurement accuracy, mainly used for accurate measurement of displacement and position in use, so do you know what is the influence of temperature on LVDT displacement sensor? Effect of temperature change on the output signal ...
1. The scale of the sensor: (1) In normal use (static test or quasi-static test, the frequency of use is not high), the scale of the sensor should be selected to consider the force value of the measurement, but also to consider the weight of the auxiliary thing (test fixture) and so on.
1. Determination mechanism The commonly used torsional strain gauge is attached to the ductile shaft to be measured with strain adhesive and forms a strain bridge, which supplies power to the strain bridge. The electrical signal of torsion on the elastic shaft is immediately determined. After the strain signal is enlarged, it is changed to the positive and negative parts of the torsional strain after the voltage/frequency change.
Turck's linear displacement sensors have an additional measuring stroke of 100 to 4500 mm. It uses the magnetoelastic principle and non-touch measurement method, and provides a high accuracy of μm according to the 16-bit D/A conversion resolution. It can be changed according to the actual application needs through a very simple programming method.
1. Shielding skills Containers are made from metal materials. Wrapping circuits that require maintenance between them can effectively prevent the disturbance of electric or magnetic fields, and this method is called shielding. Shielding can be divided into electrostatic shielding, electromagnetic shielding and low-frequency magnetic shielding. 2. Electrostatic shielding ...
** is the pressure, the transmitter can't lose it. In this case, look at the pressure connector to see if it leaks or is clogged, if it admits not, look at the wiring and see if the power supply is normal, simple pressure to determine if the output has changed, or if there is an output at the zero point of the sensor, ...
1. Understand the circuit principle and determine the maintenance plan: when the electrical system of a piece of equipment has shortcomings, do not rush to disassemble it, first of all, it is necessary to understand the phenomenon, pass, planning and reasons for the shortcomings of the electrical equipment. Understand the basic operating principle of the equipment and electrical system, and analyze the details of the equipment.
1. The AC contactor can replace the DC contactor in an emergency, and the suction time can not exceed 2 hours (because the heat dissipation of the AC coil is worse than the DC coil, which is determined by their different structures).
(1) Whether the temperature of the measured target needs to be recorded, alarmed and automatically controlled, and whether it needs to be measured and transmitted at a distance. (2) The size and accuracy of the temperature measurement range. (3) Whether the size of the temperature measuring element is appropriate. (4) When the temperature of the measured target changes with time, the temperature measuring element lags behind ...
