Sensors have been widely used in the construction machinery industry. The sensor device can output various physical and chemical signals as electrical signals, such as gravity, temperature, sound, distance, etc., so that the staff can directly control or adjust the data detected by the sensor.

FST load cells offer wide capacity ranges for both mobile crane and stationary crane, acquire the real time monitoring of weighing data, and feedback to control system, guarantee safe operation of load and unload containers. MH position sensors acquire the real time monitoring for cylinder positioning, guarantee safe displacement of each moving parts. PT08 Pressure transmitters acquire the real time monitoring of pressure value of hydraulic oil in the system, guarantee hydraulic pump will work properly, if pressure range exceed the specified limit value, pressure transimitters will send the alarm signal to the system in time.

Production Process of load cellLoad cell instruments aim to highlight the actual mass of a material. They are produced based on the principles of mass measurement under fluid pressure, elasticity, magnetic effect, piezoelectric and zero environments. The two basic components of a load cell are the s

Materials of load cellLoad cells are made of various metallic parts, such as: alloy steel, stainless steel, aluminum, and tool steel. Each material offers something different in the way of properties; each is suited in one way or another to be used for load cells. Some of their various properties in

Modern load cells work using a combination of the Wheatstone bridge equation and the strain gauge. The Wheatstone bridge equation was developed in 1833 by Samuel Hunter Christie, and improved upon and popularized in 1843 by Sir Charles Wheatstone. Wheatstone bridge circuits illustrate the concept of a difference measurement. Today, load cells are usually made up of four strain gauges in a Wheatstone configuration.

Load cells have a specified load direction, do not apply side forces, bending or torsional movements on load cells. Inappropriate loading applications will risk reducing the life of load cells, plus distortion of correct measurement results.

The most popular type of force torque sensor is the six-axis sensor. This particular force torque (FT) sensor is capable of measuring forces in every direction. A six-axis FT sensor generally utilizes strain gauge technology; when pressure is applied, the resistance within the gauge increases or decreases proportionally to the force it receives. This is how the sensor measures the movement of its external frames in relation to one another. Six-axis sensors can be found in robotic arms at the “joint.”

The basic principle, it is a measure of the “force” being used (or attempting) to turn an element. This measurement is achieved by the use of strain gauges bonded to the shaft, measuring the strain, induced in the shaft by the applied torque or “force”.

① Ambient Conditions Humidity, pressure, temperature, etc. of the medium surrounding the load cell. ② Ambient Temperature The temperature of the medium surrounding the load cell. ③ Angular Load Eccentric A load applied eccentric with the primary axis at the point of application and at some angle with respect to the primary axis.

How to select the appropriate sensor When we provide sensing solutions, it is very important to choose the right products. There are so many kinds of sensors. Once the selection is not good, it will bring a lot of issues to the application.
