Key points of maintenance of electronic crane scales, automobile weighbridges, electronic forklift scales, unique effect electronic scales, and the outer dial of Dongguan electronic weighbridge weight sensor:
Problem detection and analysis in the use of load cells, the common problems of the weighing appearance of automation technology have been the primary manifestation of the digital display appearance of the terminal equipment of the system software, and the primary performance of the common problem conditions, do not blindly dismantle the load cell, and should first identify which link of the measurement system the problem comes from. The following methods can be adopted:
1. Open the terminal of the central indirect wire, and use a digital multimeter to check the operation status of each inductor to distinguish whether a certain sensor has a common problem. Use the described method to narrow the scope of common problems, find out the problem sensor, understand the operation status of the problem in time, and diagnose the problem. Therefore, the problems caused by the sensor are often related to illegal operation or abnormal mechanical devices;
2. Check the installation status of the mechanical device of the Interface MBI shear load cell;
3. Clear the equipment problem and use the shake table to check whether the cable is injured.

How sensor detection avoids interference – ifm
Sensor detection is known to prevent disturbances. Once disturbed, the sensor may be damaged, the measurement system will be affected, the inaccurate data will affect the future use, the judgment will be biased, and the impact can be large or small, so anti-interference is very important. Today we're going to comment ...

Sensors, temperature sensors, RTDs and thermocouples – ifm
RTDs and thermocouples are the most commonly used temperature sensing elements for temperature sensors. The operating principle of thermocouple temperature sensor is that the two ends of the contact surface of two kinds of incompatible metals produce a weak and weak voltage when the temperature is inconsistent, and the temperature is measured by expanding the electric, which is not necessary to measure the high temperature. RTD Temperature Sensors ...

Considerations for the selection of load cells – ifm
1. Sensor scale:
(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 tool (test fixture) and so on.
