Strain gauge sensors are generally made of four wires (except shielded wires). As far as sensors are concerned, they are usually red, black, green and white. Red and black for power positive and negative (excitation). Green and white signal positive and negative (output). Use a multimeter to measure the impedance between the red line and the black line, and the impedance between the gree...
The choice of weighing sensor mainly depends on the weighing type and installation space. On the other hand, we should consider the manufacturer's suggestion. For the load cell manufacturer, the stress state, performance index, installation form, construction form and material of the elastomer are generally specified. In electronic scale, table scale, box scale, etc., steel cantilever sensor is su...
Torque sensors are used in a wide range of applications. Torque force is determined by two points: measuring torque sensor force and measuring speed. Torque sensors are not common in our daily life, but their application is very important. A reaction torque sensor in the car checks the torsion of the torsion bar and converts it into an electrical signal. This electrical signal is transmitted to th...
1、The material of the elastomer The elastomer material of the force sensor is usually made of metal. Most of the available materials are aluminum alloy material, alloy steel material and stainless steel material. The alloy material not only has stiffness to ensure deformation consistency and deformation recovery, but also has good weather resistance and corrosion resistance. The main requir...
The general parameters of the force sensor are the technical parameters of the sensor, including the most important range, sensitivity, accuracy index, excitation voltage, input and output resistance, wiring definition and so on. For a user who has never used a force transducer, how to do post signal processing? In general, the principle of strain type sensor is wheatstone bridge. From the wiring ...
Force sensors can have problems if they are exposed to manufacturing conditions beyond the limits specified by the supplier during storage or assembly. 1. The temperature High ambient temperature is one of the common causes of many problems in pressure load cells. Because the pressure sensor has many components which can only work properly within a specified temperature range. Exposing in environm...
The separation of three concepts of activity, accuracy and resolution of force sensor: Usually, we often refer to the activity, accuracy and resolution of pressure sensor. However, many people are not very clear about the difference between these three parameters, leading to big and small problems in application. Below, we give a brief introduction to the differences between the activity, accuracy...
Torque sensors can be mounted horizontally or vertically. Power equipment, torque transducer, load equipment should be installed on a stable basis to avoid excessive vibration, otherwise there may be data instability, reduce the measurement accuracy, and even damage the sensor. We try to use elastic pin couplings or rigid couplings during installation. During installation, the concentricity of the...
